CT Scans Increase Cancer Risk in Children



A new study estimates that CT scans performed on children this year will result in almost 5,000 new cases of cancer.


 

CT SCANS INCREASE CANCER RISK IN CHILDREN

As I discuss in my book, A Cancer Prevention Guide for the Human Race, exposure to medical x-rays has only recently been linked to a significant increase in cancer risk, particularly with the use of CT scans that expose patients to relatively large radiation doses at one time.  In fact, the prestigious Institute of Medicine has estimated that as many as 2 percent of all cancer cases are caused by exposure to medical x-rays.

Although cancer is more common during late adulthood, children are also at risk of developing cancer.  Moreover, due to ongoing rapid growth, children are more sensitive to the cancer-causing effects of radiation exposure than adults.

A newly published study, in the journal JAMA Pediatrics, further raises concerns about the current use of CT scans in children.

In this study, the use of CT scans between 1996 and 2010 in children under the age of 15 was analyzed.  Additionally, actual radiation doses were calculated for 744 CT scans performed on children between 2001 and 2011.

Between 1996 and 2006, the use of CT scans doubled among children younger than 5 years of age, and tripled among children between 5 and 14 years of age.  Between 2006 and 2007, the number of CT scans remained stable, and then began to decline somewhat after 2007.

After calculating the radiation dose associated with individual CT scans, the authors of this study calculated that one new case of cancer would be induced in girls for every 300 to 390 CT scans of the abdomen performed, and for every 330 to 480 CT scans of the chest.

When considering the estimated 4 million CT scans performed on children every year in the United States, the authors of this research study estimated that 4,870 children will go on to develop cancer as a result of having undergone a CT scan.  At the same time, they also estimate that reducing the highest 25 percent of CT scan radiation doses to lower levels could prevent at least 43 percent of these radiation-induced cancers.

CT scans can provide enormously important information to treating physicians, but many CT scans performed (on both adults and children) are of questionable clinical value.  Therefore, as a first step in reducing radiation exposure, CT scans should only be ordered when necessary, and only when other types of scans (e.g., plain x-rays, ultrasound or MRI scans) will not suffice.  Secondly, as I have discussed previously, both in A Cancer Prevention Guide for the Human Race and on my website, there is great variability between hospitals, and even within individual hospitals, in the amount of radiation that is used to perform otherwise identical CT scans; and as the authors of this study note, simply reducing excess radiation levels when performing CT scans may cut the number of cancers induced by CT scans nearly in half!

Why We Eat Far More Calories than We Think



A new study shows that we greatly underestimate how many calories we consume.


 

WHY WE EAT FAR MORE CALORIES THAN WE THINK

As I discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, it is critically important to avoid diets and foods, and other lifestyle choices, known to increase the risk of cancer.  As I also discuss in my book, the human body was not designed for the supra-normal calorie content of the typical “western diet.”  The enormous number of calories packed into the highly processed foods that most people favor, when combined with our increasingly sedentary lifestyle, has led to an epidemic of obesity and obesity-related diseases, including cancer, diabetes, high blood pressure, heart disease, stroke, gallstones, liver disease, and accelerated arthritis, among other preventable serious illnesses.  Another point that I make in my book, and in discussions with my patients, is that almost all of us greatly underestimate the number of calories that we are consuming while, at the same time, we tend to overestimate the number of calories that we are burning through physical activity.

A newly published public health study, which appears in the current issue of the British Medical Journal, provides compelling data regarding our predisposition towards underestimating just how many calories we consume on a daily basis.

In this study, 1,877 adults, 1,178 adolescents, and 330 school-age children were asked to estimate the approximate number of calories that they were consuming while eating at fast food restaurants.  Specifically, these surveys were performed at McDonalds, Burger King, Subway, Wendy’s, KFC, and Dunkin’ Donuts.

The actual calories count, on average, for each meal was 836 calories for adults, 756 calories for adolescents, and 733 calories for children.  When asked to estimate the numbers of the calories they had just consumed, the adults underestimated their caloric intake by an average of 175 calories, the adolescents by 259 calories, and the school-age children by 175 calories.  Perhaps more important was the observation that the degree of underestimation of calorie content of fast-food meals actually increased with increasing actual meal calorie counts.  That is to say, the more excessive calories that people consumed at these fast-food restaurants, the more they underestimated their actual caloric intake.  Another interesting finding of this public health study was that adults and teens who ate at Subway underestimated the calorie counts of their meals to a greater degree (20 and 25 percent, respectively) than people who ate at McDonald’s, suggesting an inaccurate perception that Subway meals contained fewer calories (and were, therefore, healthier) than McDonalds meals.

As I discuss in my book, excess body weight has been linked to 7 to 10% of all cancer cases, as well as many other life-threatening obesity-related illnesses.  Therefore, instead of underestimating the calorie content of our diets and overestimating how physically active we are, we would be much better off by sharply reducing the calories we consume and increasing our physical activity levels.  Take an important first step towards living an evidence-based cancer prevention lifestyle now by reading A Cancer Prevention Guide for the Human Race.

Helping Others Reduces Heart Disease Risk Factors



A new clinical study reveals that performing acts of kindness can lower our personal risk of heart disease.


 

HELPING OTHERS REDUCES HEART DISEASE RISK FACTORS

Booker T. Washington once said, “Those who are happiest are those who do the most for others.”  Certainly, most of us would agree that lending a helping hand benefits both the person in need and the person who has volunteered to help.  Other than the satisfaction of knowing that you have made a positive difference in the life of another person, however, are there other potential benefits associated with altruistic behavior?   Well, a newly published prospective randomized clinical research study suggests that volunteering to help others may actually improve the heart health of those who lend a helping hand to others in need.  This study appears in the current issue of the journal JAMA Pediatrics.

A total of 106 tenth grade students agreed to participate in this prospective randomized clinical research study. The student volunteers were divided into two groups. The first group was assigned to volunteer to work with elementary school children on a weekly basis, while the other group (the “control” group) did not participate in any volunteer activities. At the beginning of this clinical study, measurements of the following cardiovascular disease risk factors were performed on all study participants: C-reactive protein level, interleukin 6 level, total cholesterol level, and body mass index. These same heart disease risk factors were measured again 4 months later.

The findings of this study were quite interesting. The results of testing at the beginning of this study revealed no significant differences in the measured cardiovascular disease risk factors between the two groups of study participants. However, 4 months later, significant differences in these established cardiovascular risk factors were observed between the two groups of high school students. Specifically, interleukin 6 levels, total cholesterol levels, and body mass index (a measure of weight versus height) were all significantly improved within the “volunteer group” when compared to the control group. While marginally significant, blood levels of the inflammatory C-reactive protein were also noted to be lower in the group of teens that had been randomized to work with elementary school children. Most interesting was the observation that the greatest decrease in these cardiovascular risk factors occurred, over time, among the teens in the volunteer group who also demonstrated the greatest increase in empathy and altruistic behaviors, and the largest decrease in negative mood, during the course of this study.

The findings of this very novel prospective randomized clinical study suggest that engaging in acts of empathy and altruism may directly lead to a reduction in several well known cardiovascular disease risk factors, although this study did not follow its very young volunteers long enough to determine whether or not the act of volunteering to help others actually reduced the incidence of cardiovascular disease.  However, based upon this innovative study’s findings, it certainly appears that helping others is a definite win-win situation.  The persons being helped obviously benefit from the acts of empathy and altruism bestowed upon them by others.  At the same time, not only does it feel good to help others in need, but the person who voluntarily reaches out to another may very well reap, in turn, the benefit of improved health!  (Another positive finding of this study is that this very positive phenomenon apparently works on teenagers!)

As I discuss in A Cancer Prevention Guide for the Human Race, living an evidence-based cancer prevention lifestyle not only reduces your risk of dying from cancer, but also reduces your risk of dying from cardiovascular disease as well!

Acts of Kindness Improve Social Acceptance Among Pre-Teens



A new study confirms that acts of kindness improve happiness and social acceptance among pre-teens.


 

ACTS OF KINDNESS IMPROVE SOCIAL ACCEPTANCE AMONG PRE-TEENS

Some have observed that “nice guys finish last,” and, indeed, there is some data to suggest that, in the corporate world at least, the arrogant are, ironically, often viewed as more motivated, more goal-oriented, and more deserving of advancement when compared to their less aggressive peers.  However, most of us would like to believe that a kind and caring heart will be rewarded in life, and rewarded by others.  But, is there any objective evidence that kindness really does beget happiness and kindness?  According to a newly published clinical study from Canada, kindness really does appear to increase our personal sense of well-being, as well as increasing the likelihood that others will regard us kindly in return.  Moreover, the social benefits of being kind towards others appear to begin relatively early in life, as this newly published study in the journal PLOS ONE reveals.

For teenagers, and for those on the cusp of adolescence, being accepted and being liked by one’s peers is of the utmost importance.  Indeed, young people who feel excluded from social groups at school often end up feeling like outcasts, and may suffer considerable long term injury to their self-confidence and self-esteem.  In this newly published clinical study, 415 children between the ages of 9 and 11 years volunteered to participate in this study for a period of 4 weeks.  These young volunteers were randomly assigned either to perform 3 acts of kindness or, instead, to visit 3 places on a weekly basis.  At the end of week, each student was asked to report on their activities during the previous week.  

At the end of this 4-week study, both groups of students experienced measurable improvements in their sense of well-being.  However, the students who were assigned to complete 3 acts of kindness per week experienced a significantly greater improvement in acceptance and approval by their student peers (based upon confidential classroom surveys) when compared to the student volunteers who had been randomized to visit 3 places per week.

The authors note in their conclusion that, based upon the findings of this study, “doing good” for others benefits not only the recipients of kind acts, but also the person who is performing the kind acts as well.  Furthermore, in view of the importance of being accepted by one’s peers, and of being happy, during the pre-teen and teenage years of our lives, the finding that simple acts of kindness increase both acceptance by social peers and internal happiness are very important findings, indeed.  Other important findings from this study include the observation that children who are well-accepted by their peers are more inclusive in their actions towards others, and are less likely to engage in exclusionary behaviors towards others, including bullying (or worse…).  At the classroom level, the authors of this study also note that the absence of both favored and marginalized children is associated with improved overall classroom mental health.  Based upon the findings of this intriguing study of pre-teen children, the authors suggest that teachers and parents should strive to introduce a culture of regular “acts of kindness” and inclusion within classrooms, which sounds like a very good idea to me.

Obese Fathers (Not Obese Mothers) Increase Their Children’s Risk of Obesity






A new study finds that paternal obesity significantly increases the risk of obesity in children, but not maternal obesity.


 

 

OBESE FATHERS (NOT OBESE MOTHERS) INCREASE THEIR CHILDREN’S RISK OF OBESITY

The incidence of obesity has skyrocketed over the past 10 years, and at this time, nearly two-thirds of Americans are either overweight or obese.  Moreover, fat- and sugar-packed foods, combined with sedentary lifestyles, have resulted not only in an epidemic of obesity among adults, but even our children and teens are heavier than ever before.

A newly published prospective public health study, the Longitudinal Study of Australian Children, has reported a rather interesting finding regarding obesity patterns in Australian families.  This study, which appears in the current issue of theInternational Journal of Obesity, followed more than 3,000 men, women and children in two-parent families between 2004 and 2008.  Height and weight data was collected on all family members during this 4-year study.

Not surprisingly, obesity was more common, in general, among the children of obese parents.  However, a very interesting phenomenon was observed in that childhood obesity was significantly associated with having an overweight or obese father and a mother of normal weight, but not with having a normal weight father and an overweight or obese mother.  In this study, children with an overweight or obese father (but a normal weight mother) were nearly 15 times more likely to be obese than children without obese parents.  (Once again, however, having an overweight or obese mother, and a normal weight father, was not associated with an increased risk of childhood obesity when compared to children with normal weight parents.)

While this study was not designed to explain why paternal obesity appeared to increase the risk of childhood obesity, while maternal obesity apparently did not, this unexpected finding suggests that either behavioral or genetic factors (or both) linked to obesity in fathers have a particularly strong impact on their children’s risk of also becoming overweight or obese.  The results of this study also suggest that interventions to prevent childhood obesity may be especially important in families with overweight or obese fathers.

As I discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, the incidence of obesity has skyrocketed over the past 10 years, and obesity is known to significantly increase the risk of multiple types of cancer, including cancers of the breast, esophagus, pancreas, kidney, uterus, colon, rectum, and other organs.  In fact, even conservative estimates suggest that at least 10 percent of all cancer cases are directly linked to obesity.  If you are overweight or obese, please consult with your doctor about safe, evidence-based approaches to weight loss.

Cell Phone Use in Children and Teens and Brain Tumor Risk

Welcome to Weekly Health Update


New research suggests that the risk of brain tumors in children and teens associated with routine cell phone use is probably quite small.



 

CELL PHONE USE IN CHILDREN AND TEENS AND BRAIN TUMOR RISK

A possible link between cell phone use and brain tumor risk continues to cause concern among cancer experts.  However, because it would be unethical to intentionally expose human research subjects to prolonged periods of cell phone radiation exposure, it is not possible to perform a prospective, randomized, blinded study to completely resolve this important potential health issue.  Because of this human research limitation, we are left with retrospective research studies that have attempted to estimate potential health risks associated with cell phone exposure (based primarily upon self-reported cell phone use among patients with brain tumors and those without brain tumors).  Therefore, it is not surprising that there are conflicting research results on this topic, with some studies suggesting an increased risk of brain tumors associated with prolonged cell phone use and other studies finding no apparent increased risk of brain tumors with cell phone use.  (I discuss much of this available research in my book, A Cancer Prevention Guide for the Human Race.)

Because cell phone use clearly exposes the head and brain to some level of microwave radiation (and particularly when cell phones are used without hands-free devices), there has been particular concern about the possibility of brain injury and brain tumor formation among children and adolescents who use cell phones, as not only are their skulls thinner than those of adults, but their rapidly growing brains are thought to be more sensitive to any insults that might increase the risk of brain injury or brain tumor formation.

A newly published clinical research study, which appears in the current issue of the Journal of the National Cancer Institute, represents an important advance in our understanding of the impact of cell phone use on brain tumor risk in children and adolescents. This European study is a case-control study, which compared children and adolescents (ages 7 to 19 years) who were diagnosed with brain tumors with “control subjects” (i.e., healthy children of the same age, sex, and geographical region, and who did not have brain tumors). In this case-control study, interviews were conducted with 352 children and adolescents (and their parents) who had been diagnosed with brain tumors, as well as 646 children and adolescents (and their parents) without a history of brain tumors. A novel approach in this particular clinical research study was the use of mobile phone records, in an attempt to improve the accuracy of self-reported cell phone use by the research volunteers.

The results of this study failed to find any association between the amount of cell phone use and brain tumor risk. Furthermore, there was no apparent association between the location of tumors in the brain and the areas of the brain that are known to receive the highest levels of microwave radiation from cell phone handsets.

The findings of this case-control clinical research study offer some reassurance that routine cell phone use probably does not significantly increase the risk of brain tumors in children and adolescents. However, I would caution readers that other similar studies have suggested an increased risk of at least benign brain tumors among people who extensively use cell phones over long periods of time. Moreover, recent research has shown that metabolism significantly increases in the areas of the brain that are exposed to the greatest amount of radiation during cell phone use, thus proving that brain exposure to cell phone radiation does indeed alter brain function during cell phone use.

In the absence of high-level clinical research data from a prospective, randomized, double-blinded clinical research study, my wife and I limit cell phone use by our two younger children to no more than 5 minutes at a time, and this is my recommendation to readers and patients as well.
