Fish Oil May Increase Prostate Cancer Risk



A new study suggests that high levels of fish oil in the blood may increase prostate cancer risk.


 

FISH OIL MAY INCREASE PROSTATE CANCER RISK

As I discuss in my book, A Cancer Prevention Guide for the Human Race, there is research evidence available suggesting that omega-3 fatty acids, which are abundant in fatty fishes and fish oil supplements, may potentially decrease the risk of breast cancer and other types of cancer.  Indeed, in a recent column I reviewed a new study that strongly suggested a role for fish oil supplements in the prevention of breast cancer (Fish Oil May Decrease Breast Cancer Risk).  Now, a newly published clinical research study suggests that fish oil may increase the risk of prostate cancer, and aggressive forms of prostate cancer in particular.  This newly published study appears in the current issue of the Journal of the National Cancer Institute.

In this study, 834 men diagnosed with prostate cancer were compared with 1,393 age-matched men without prostate cancer. All of these men underwent measurement of the levels of fish oil-derived omega-3 fatty acids (EPA, DPA and DHA) in their blood.  After measuring and comparing the levels of fish-derived omega-3 fatty acids in the blood of these research volunteers, the researchers found that the volunteers with the highest levels of these omega-3 fatty acids were 44 percent more likely to be diagnosed with favorable forms of prostate cancer, and 71 percent more likely to be diagnosed with more aggressive forms of prostate cancer, when compared to the men with the lowest levels of fish-derived omega-3 fatty acids in their blood. Overall, men with the highest levels of fish-derived omega-3 fatty acids in their blood were 43 percent more likely to be diagnosed with any form of prostate cancer when compared to men with the lowest levels of fish oil-derived omega-3 fatty acids in their blood.  On the other hand, men with the highest blood levels of fatty acids derived from plants (omega-6 fatty acids) actually had a 23 percent lower likelihood of developing any form of prostate cancer.

As I have pointed out often before, studies such as this one can point out potential associations between specific lifestyle habits and the risk of cancer (or other diseases).  However, they cannot truly prove a “cause-and-effect” relationship between individual lifestyle factors and disease risk.  To arrive at this higher level of proof, a large prospective, randomized, placebo-controlled, blinded clinical research trial is necessary.  However, given that this is not the first research study to link high levels of fish-derived omega-3 fatty acids with an increase in prostate cancer risk, I have recently cut back on my own intake of both fish and fish oil supplements.  (Like millions of other people who take fish oil supplements and who regularly eat fish, I long ago added these items to my diet in the hope that I would significantly reduce my risk of cardiovascular disease.  However, a recent prospective, randomized, placebo-controlled clinical study of fish oil supplements in patients at elevated risk for cardiovascular disease showed no apparent reduction in the risk of heart attacks or strokes, or other cardiovascular disease events, among the research volunteers who were randomized to receive fish oil supplements.)

Until a large-scale prospective, randomized, blinded, placebo-controlled study is performed to validate the findings of this “case-cohort” public health study, it would seem prudent to cut back on daily fish oil supplements, which I myself have done.

Coffee May Reduce Prostate Cancer Risk



A large new study strongly links coffee consumption to a decreased risk of developing prostate cancer.


 

COFFEE MAY REDUCE PROSTATE CANCER RISK

An estimated 240,000 men will be diagnosed with prostate cancer in the United States in 2013, and nearly 30,000 American men will die from this form of cancer in 2013. As is the case with breast cancer in women, prostate cancer is the most common type of cancer (other than skin cancer) in men and the second most common cause of cancer death in men. (Sadly, lung cancer, an almost completely preventable form of cancer, remains the #1 cancer killer in both men and women.) As I discuss in my cancer prevention book for lay readers (A Cancer Prevention Guide for the Human Race), in the chapter dedicated to prostate cancer, there are multiple modifiable lifestyle factors that have been linked to prostate cancer risk.

Coffee consumption, like many other dietary factors potentially linked to prostate cancer risk, has been evaluated in several previous public health studies, but the data from these mostly small-scale studies has been contradictory. However, a newly published large-scale prospective public health study suggests that coffee consumption may, indeed, be associated with a significant reduction in the risk of developing prostate cancer. This important new study appears in the current issue of theBritish Journal of Cancer.

This Japanese study recruited 18,853 men between the ages of 40 and 79 to participate in this very large prospective public health study. A previously validated survey was given to all of these men, and questions about dietary habits, including coffee consumption, were included in this survey. This very large group of middle-aged and elderly men was closely followed for an average of 11 years, during which 318 of these nearly 19,000 male volunteers were diagnosed with prostate cancer.

Compared with the men who did not drink coffee at all, men who drank coffee occasionally (i.e., less than one cup per day, on average) were 19 percent less likely to develop prostate cancer, although this finding did not quite reach statistical significance. As would be expected if coffee truly played a role in reducing prostate cancer risk, increasing levels of coffee consumption were associated with greater reductions in prostate cancer risk. For example, men who drank 1 to 2 cups of coffee per day were, on average, 27 percent less likely to develop prostate cancer (compared to nondrinkers), while men who drank 3 or more cups of coffee per day were 37 percent less likely to be diagnosed with prostate cancer. (These latter two findings were found to be statistically significant.)

While I frequently caution readers that the findings of most small-scale public health studies on disease prevention are not definitive, larger prospectively conducted public health studies, such as this one, and particularly studies with long-term follow-up (such as this one), are much more likely to generate valid observations and conclusions. Since there is little apparent downside to moderate coffee consumption, the findings of this study would appear to support the consumption of coffee (again, in moderation…) as a component of what I call, in A Cancer Prevention Guide for the Human Race, an “evidence-based cancer prevention lifestyle.” So, go ahead and have a cuppa joe, or two, each day, men!

Hold the Bacon: Processed Meats Linked to Early Death



A new study links the consumption of processed meats with a significant risk of early death.


 

HOLD THE BACON: PROCESSED MEATS LINKED TO EARLY DEATH

As I extensively discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, red meat and processed meats (such as bacon, sausages, and luncheon meats) have been directly linked to an increased risk of multiple different types of cancer, including cancers of the breast, prostate, esophagus, stomach, pancreas, kidney, bladder, colon, and rectum. Moreover, diets rich in these meat products are also associated with a higher risk of that other great killer of mankind, cardiovascular disease.  Now, a newly published public health study puts the impact of a meat-rich diet into stark perspective. This important new clinical study appears in the current issue of the journal BMC Medicine.

Nearly 450,000 men and women between the ages of 35 and 69 have participated in a huge ongoing prospective public health study, the European Prospective Investigation into Cancer and Nutrition (EPIC), making this one of the largest prospective clinical research studies ever undertaken. All of these study volunteers were without clinical evidence of cancer, stroke, or cardiovascular disease at the time they entered into this clinical study. At the time when data from the EPIC study was collected for this analysis, after almost 13 years of follow-up on average, 26,344 study volunteers had died since enrolling in the study.

Following extensive statistical analysis of the huge amount of data collected in this study, the increased consumption of processed meats was linked to a 44 percent increase in the risk of death from all causes, including cardiovascular (heart) disease and cancer. Red meat was also associated with an increase in the risk of death due to all causes, although not to the same extent as was observed with processed meats. (As with multiple previous studies, this study also found no association between the consumption of poultry and an increase in the risk of death from any cause.)

Based upon their analysis of the data, the researchers who conducted this gigantic public health study concluded that more than 3 percent of the deaths observed in this study could have been prevented if all study volunteers had decreased their processed meat intake to less than 20 grams (0.7 ounces) per day.

As I discuss in A Cancer Prevention Guide for the Human Race, our dietary and other lifestyle choices can have an enormous impact on our overall health, including our risk of cancer and cardiovascular disease. If you seek to minimize your risk of these two great killers of modern mankind, and you wish to begin living an evidence-based cancer prevention lifestyle now, then get your copy of A Cancer Prevention Guide for the Human Race from your favorite bookstore!

Resveratrol May Reduce Cancer Risk and Cancer Cell Growth



 

A new study suggests that resveratrol may reduce cancer risk and cancer progression.



 

 

 

RESVERATROL MAY REDUCE CANCER RISK AND CANCER CELL GROWTH

As I discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, resveratrol, a plant-derived phenol, has been found, in laboratory studies, to potentially reduce the risk of both cardiovascular disease and cancer, and may increase longevity as well (at least in laboratory animals…).

Resveratrol’s anti-cancer effects have been observed in multiple laboratory studies using cancer cells grown in culture and in laboratory animals.  (Unfortunately, there is very little clinical data available regarding the effects of resveratrol in humans.) However, the precise mechanisms whereby resveratrol may inhibit the development and growth of cancer cells remain unclear at this time.  Now, a newly published study, which appears in the journal Cancer Prevention Research, sheds some important scientific light on at least one mechanism whereby resveratrol may inhibit cancer cell development and growth.

In this two-part laboratory study, resveratrol was found to increase the production of the enzyme SIRT1, which appears to play an important role in suppressing cancer cell growth and survival.

In the first part of this study, human prostate cancer cells were exposed to resveratrol, which resulted in an increase in the production of SIRT1, and an associated decrease in tumor cell growth and survival.

In the second part of this study, a strain of mice predisposed to developing prostate cancer had their food supplemented with resveratrol.  When compared to similar mice that did not receive resveratrol supplements, exposure to dietary resveratrol resulted in a significant decrease in prostate gland size, and, more importantly, a significant reduction (54%) in precancerous changes (high-grade prostatic intraepithelial neoplasia, or HGPIN) within the prostate gland.  When the prostate glands of the resveratrol-supplemented mice were tested, increased levels of the SIRT1 enzyme were also confirmed.

This study showed that resveratrol increases SIRT1 levels, which may, in turn, reduce the development of precancerous changes that can lead to the development of prostate cancer (and, potentially, other types of cancer as well).  This study also showed that resveratrol may also be able to reduce the growth and survival of human prostate cancer cells.

There are a couple of very important caveats to mention with regards to this study.  First of all, as I have repeatedly noted before, what works on cancer cells growing in a laboratory dish, or in genetically altered laboratory animals, often fails to work on human beings.  Secondly, there is no long-term clinical data looking at the effects (either good or bad) of resveratrol supplementation in humans.  Finally, resveratrol is poorly absorbed in humans, and relatively high (and frequent) oral intake of this compound is required to achieve blood levels comparable to those concentrations used in most laboratory studies. Fortunately, at this time there are approximately a dozen human research studies underway that are assessing the impact of resveratrol supplementation on cancer risk and cancer-associated survival.  Hopefully, some of these ongoing clinical studies will shed additional important scientific light on the potential of resveratrol to prevent and treat cancer in humans, although the findings of these studies are still years away.

Multivitamins and Cancer Risk: Reading Between the Lines





 

A new study in the Journal of the American Medical Association claims that a daily multivitamin supplement reduces cancer risk….


 

 

MULTIVITAMINS AND CANCER RISK: READING BETWEEN THE LINES

As I discuss in my book, A Cancer Prevention Guide for the Human Race, recent high-level studies of common vitamins, including antioxidant vitamins, has dimmed the prior enthusiasm that these micronutrients can reduce the risk of cancer, or cardiovascular disease, in otherwise healthy individuals who eat a balanced diet.  Moreover, recent prospective, randomized, placebo-controlled clinical studies have actually suggested that taking supplements of Vitamin E and Vitamin A (including beta-carotene) may actually be harmful to our health, while recent similar studies of Vitamin C supplements have shown neither apparent benefit nor harm.

Despite the almost uniformly discouraging recent research findings regarding most nutritional supplements and their alleged ability to decrease our risk of cancer and other serious illnesses, many people (as well as nutritional supplement manufacturers…) continue to hold out hope that popping a daily vitamin pill, or other nutritional supplement, will protect them from cancer and other dreaded diseases.  (Meanwhile, most people still tend to ignore the evidence-based cancer prevention lifestyle and diet practices that I describe in A Cancer Prevention Guide for the Human Race, and which have been linked, by hundreds of reputable clinical research studies, with a 40 to 60 percent reduction in cancer risk.)  So, it is not surprising to see the extensive and favorable media coverage that is being given to a newly published clinical study looking at the potential impact of daily multivitamin supplements and cancer risk, and which appears in the current issue of the Journal of the American Medical Association.

The Physicians’ Health Study II is a large, ongoing, prospective, randomized, placebo-controlled study of 14,641 male physicians in the United States.  All of these men were at least 50 years of age when they entered into this public health study (the average age of all study participants when they entered into this study was 64 years of age).  This study has observed health outcomes in this very large group of male physicians for an average of 11 years now, and the study’s authors have now reported on the impact of taking a daily commercial multivitamin supplement upon cancer risk and cancer-associated death rates.

To summarize the findings of this very large public health study, the male physicians in this study were secretly randomized to receive either Centrum Silver (a commercial multivitamin and mineral supplement) or a placebo (sugar) pill.  At the time of their entry into this study, 1,312 of these male volunteers were noted to have a prior personal history of cancer.  Following more than 11 years of observation, 2,669 of these physician volunteers were subsequently confirmed to have developed cancer, including 1,373 cases of prostate cancer and 210 cases of colorectal cancer.  When compared with the men who were randomly (and secretly) assigned to the placebo group, the men who were assigned to the multivitamin supplement group experienced an observed, and modest (8 percent), but still significant, reduction in the risk of being diagnosed with cancer.

While this 8 percent reduction in overall cancer risk has been widely trumpeted by other media sites, it is important to note several significant caveats before you run out to the drugstore and buy a case of Centrum Silver.  When one looks at the statistical analysis of the data that resulted in the claimed 8 percent reduction in cancer risk, one immediately notices that the so-called “confidence interval” for this claim extends to 0.998, which is right up against the limit of 1.0 that would render these findings statistically insignificant.  Therefore, the single, sole positive finding in this study of a modest decrease in overall cancer incidence is, itself, at the very borderline of what most statisticians would consider to be a statistically significant finding.

In addition to the single modest (and only barely statistically significant) positive finding of this study, as I have noted above, there was no significant correlation between multivitamin use and the risk of developing prostate cancer, colorectal cancer, or, indeed, any other individual type of cancer.  The absence of any identifiable decrease in the risk of any individual type of cancer in this study, likewise, further calls into question the validity of this study’s single, and statistically borderline, positive finding of an 8 percent reduction in overall cancer incidence among the group of men who were randomized to receive a daily multivitamin tablet.  Moreover, this study also failed to reveal any detectable reduction in the cancer-associated death rate among the men who received a daily multivitamin tablet.

The rather breathlessly favorable media reaction to this study’s conclusions vividly illustrates how the superficial reporting of seemingly favorable clinical research findings can mislead the public into accepting overblown or invalid conclusions, such as those made by the authors of this particular research study.  As I discuss in A Cancer Prevention Guide for the Human Race, most of the published research in the area of cancer prevention research is of relatively low quality in terms of the methods used to conduct such research.  Moreover, as this particular prospective, randomized, placebo-controlled study shows, even clinical studies that actually utilize higher level methodologies still require both a careful and critical analysis of their findings and claims, and the conclusions of such studies should not be simply accepted at face value.  While this multivitamin study makes the very simple and straightforward claim that taking a commercial multivitamin and mineral supplement “significantly” reduces the incidence of cancer (at least among middle-aged and elderly male physicians), even a cursory evaluation of this study’s data and conclusions confirms that there is likely to be little or no overall health benefit, in terms of cancer risk and cancer-related death reduction, associated with taking a daily multivitamin and mineral supplement in otherwise healthy and well-nourished adults.  As the old saying goes, if something seems too good to true, it probably isn’t…..

Aspirin Dramatically Reduces Prostate Cancer Death Rate






 

A new study shows that aspirin reduces the risk of death from prostate cancer by 60 to 80%.


 

ASPIRIN DRAMATICALLY REDUCES PROSTATE CANCER DEATH RATE

 

Prostate cancer is the most common of all major cancers in men, and the second most common cause of cancer-associated death in men.  Based upon data from the American Cancer Society, 242,000 men will be diagnosed with prostate cancer in the United States in 2012, and more than 28,000 American men will die of this disease this year.

 

As I discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, there are multiple evidence-based strategies available for men to decrease their risk of developing prostate cancer.  However, one area where prostate cancer prevention research in humans has been lacking is in the assessment of non-steroidal anti-inflammatory (NSAID) medications for the prevention and treatment of prostate cancer.  There is abundant scientific evidence that this class of medications (which includes aspirin, ibuprofen, naproxen, and other common anti-inflammatory drugs) can significantly reduce the risk of other types of cancer, including, notably, colon and rectal cancer.  Now, a new study involving nearly 6,000 men with prostate cancer indicates that the humble aspirin tablet appears to dramatically reduce the risk of cancer-associated death in men diagnosed with prostate cancer.

 

The prospective Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) Study enrolled 5,955 men with early-stage prostate cancer.  All of these men underwent either surgery (prostatectomy) or radiation therapy as primary treatment for their prostate cancer.  Among these nearly 6,000 patient volunteers, 2,175 were taking one or more blood thinning medications for other illnesses, including aspirin, Coumadin (warfarin), Plavix (clopidogrel), or Lovenox (enoxaprin).  The outcomes of these nearly 6,000 prostate cancer patients were carefully monitored over an average follow-up period of 70 months.  Importantly, throughout the course of this large prospective clinical study, patients were required to provide updated health information on a quarterly basis.  Moreover, their Urologists also separately provided ongoing clinical updates on these patients.  This unique study design, along with its prospective nature and its large cohort of patient volunteers, provides a very high level of clinical evidence for this study’s findings.

 

The results of this study were striking.  While the non-aspirin blood thinners appeared to have minimal impact on the death rate due to prostate cancer, the regular use of aspirin was associated with a whopping and highly significant 57 percent reductionin the risk of death due to prostate cancer among these nearly 6,000 patient volunteers.  Even more impressive was the finding that men with high-risk forms of prostate cancer were almost 5 times less likely to die of prostate cancer if they took aspirin (i.e., 4 percent risk of death versus 19 percent risk of death at 10 years, respectively), which equates to a nearly 80 percent reduction in the risk of dying from prostate cancer.

 

The findings of this study have significant public health implications.  For men already diagnosed with prostate cancer, and especially men who have prostate cancer with high-risk features, aspirin appears to dramatically reduce the risk of cancer-associated death for a period of at least 10 years, based upon the findings of this ongoing study.  Additionally, this finding that aspirin dramatically reduces the risk of cancer-associated death in men diagnosed with prostate cancer also strongly suggests that there may also be a role for aspirin as a prevention agent for prostate cancer, much as it is currently used to prevent colorectal cancer in high-risk patients.  I consider the findings of this clinical study to be of very high significance, and it should, in my opinion, compel a new randomized, placebo-controlled, double-blinded prospective study to validate these extremely impressive and encouraging findings.

 

Although favorable data supporting aspirin as a powerful cancer prevention agent continues to accumulate, the regular use of aspirin can be associated with serious, and even life-threatening, side effects, including ulcers of the GI tract, GI tract bleeding, kidney injury, and allergic reactions, among others.  Therefore, if you are thinking of adding aspirin to your list of medications, then I urge you to first discuss this with your doctor!

Vigorous Exercise Activates Cancer Prevention Genes





 

New research shows that at least 3 hours per week of vigorous exercise improves the function of multiple cancer-preventing genes.


 

VIGOROUS EXERCISE ACTIVATES CANCER PREVENTION GENES

As I extensively discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, moderate-to-vigorous physical exercise has been repeatedly shown to reduce our risk of developing cancer, as well as reducing the risk of recurrence of breast cancer and other types of cancer.  Moreover, there is research to suggest that this cancer-prevention benefit of exercise is independent of whether or not a person is overweight or obese.  However, the exact mechanism, or mechanisms, whereby exercise reduces cancer risk has not been clear, thus far.  Now, a newly presented research study offers some fascinating insights into potential biological links between exercise and cancer risk reduction.  This new study was just presented at the American Society of Clinical Oncology’s 2012 Genitourinary Cancers Symposium, and has been published in a supplement to the Journal of Clinical Oncology.

In this study, 70 men underwent biopsy of their prostate glands, which revealed normal prostate tissue.  These normal prostate tissue samples were then subjected to extensive genetic analysis.  These 70 men also completed detailed questionnaires regarding their exercise habits, which included questions that asked if they engaged in any vigorous physical activity at all, and whether or not they engaged in at least 3 hours of vigorous activity per week.

Genetic testing of these prostate gland biopsy specimens revealed that the function of 184 different cancer-related genes was significantly affected by vigorous exercise for at least 3 hours per week.  Among these observed changes in gene function was an increase in the function of the genes BRCA1 and BRCA2, which are known to reduce the risk of developing cancer (i.e., tumor suppressor genes).  In fact, inherited mutations of these BRCA genes are known to dramatically increase the risk of breast cancer (in both men and women), ovarian cancer, and prostate cancer in patients affected with these “deactivating” BRCA gene mutations.  Moreover, the function of genes which are involved in the normal growth and division of cells, and in the repair of damaged DNA, also improved in the men who reported at least 3 hours of vigorous physical activity per week.  Another important finding of this very impressive research study is that the men who reported engaging in vigorous physical activity forless than 3 hours per week did not show any improvement in cancer-suppressing gene function when compared to men who indicated that they did not engage in any vigorous physical activity.

The findings of this innovative research study are hugely important, in my view, as it is one of the first studies to identify specific genetic mechanisms that may potentially explain why vigorous exercise reduces cancer risk.  While many other clinical studies have indirectly linked increased levels of physical activity to a reduced risk of developing cancer, this intriguing research study has identified multiple actual cancer-suppressing genes whose function appears to be significantly improved, or “upregulated,” in response to vigorous, frequent exercise.  The finding that at least 3 hours of vigorous activity per week is necessary to improve the function of these critical anti-cancer genes is particularly important, and may serve as a guide as to how much exercise we need to engage in to significantly lower our risk of developing cancer.  Additionally, knowing which cancer-suppressing genes respond favorably to frequent and vigorous exercise may also help scientists to develop new strategies to manipulate these anti-cancer genes, in an effort to further reduce our risk of developing cancer.

This study is a crucial advance in our understanding of the biological mechanisms whereby higher levels of physical activity appear to reduce the risk of developing cancer.  Although this is a rather small study, its implications with respect to cancer prevention are likely to be huge!

Heart Disease May Also Increase Prostate Cancer Risk

Welcome to Weekly Health Update




New research strongly suggests that coronary artery disease may significantly increase prostate cancer risk.


 

HEART DISEASE MAY ALSO INCREASE PROSTATE CANCER RISK

As I discuss in my recent bestselling book, A Cancer Prevention Guide for the Human Race, many of the same lifestyle and dietary habits that increase our risk of developing cardiovascular disease (including coronary artery disease, heart attacks, peripheral vascular disease, and stroke) also increase our risk of developing certain types of cancer.  However, the data linking lifestyle and dietary factors with prostate cancer risk has, so far, been both weak and contradictory.  Now, a newly published study has found an apparent link between coronary artery disease and prostate cancer risk.  These findings appear in a new update of the ongoing REDUCE (REduction by DUtasteride of prostate Cancer Events) clinical trial, which I previously reported on in 2010 (), and these updated findings appear in the current online issue of the journal Cancer Epidemiology, Biomarkers & Prevention.

Among the 6,390 men enrolled in this prospective, randomized prostate cancer prevention trial, 547 men were known to have coronary artery disease at the time that they entered into this research study.  Not surprisingly, this group of men with heart disease had a greater number of risk factors for cardiovascular disease when compared to the men without coronary artery disease, including obesity, high blood pressure (hypertension), diabetes, and elevated cholesterol.    What was surprising, however, is that over the 4 year course of this clinical study, the risk of prostate cancer in this group of men with coronary artery disease was significantly higher than what was observed among the men without heart disease.  Two years into the REDUCE study, the men with a history of coronary artery disease were 24 percent more likely to be diagnosed with prostate cancer when compared to the men with healthy hearts.  After four years of participation in this clinical study, the men with known coronary artery disease were 74 percent more likely to be diagnosed with prostate cancer!

While this particular research study was not designed to determine which risk factors for cardiovascular disease were specifically involved with prostate cancer risk, as I discuss in A Cancer Prevention Guide for the Human Race, both obesity and smoking have previously been linked to an increased risk of death due to prostate cancer, and these two lifestyle factors are also strongly linked to cardiovascular disease risk.

 

Prostate cancer is the second most common cause of death due to cancer (following lung cancer) in men, and is associated with nearly 35,000 deaths each year in the United States alone.  In many ways, prostate cancer is the male counterpart of breast cancer (which is also the second most common cause of cancer-associated death in women), although prostate cancer has yet to receive the same level of attention and research funding as has breast cancer.  In my view, we men have a lot to learn from our female counterparts about raising cancer awareness, and advocating for increased research funding, when it comes to prostate cancer. Therefore, I urge all men to explore opportunities to actively support prostate cancer awareness, and improved research funding, in their local communities.
