A new clinical study suggests that performing CT scans during childhood may significantly increase the risk of leukemia and brain cancer.
CT SCANS AND CANCER RISK IN CHILDREN As I discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, exposure to medical x-rays, and particularly exposure to radiation from CT scans, is an under-appreciated cancer risk factor. Based upon even conservative estimates, exposure to medical radiation is thought to cause at least 1 to 2 percent of all new cancer cases, and most of this medical x-ray exposure comes from CT scans. Additionally, as I also discuss in my book, there is enormous variation in the amount of radiation exposure associated with CT scans between different hospitals, and even within individual hospitals. Now, a newly published clinical study suggests that the risk of cancer in children due to medical x-rays may be of particular concern. This new paper appears in the forthcoming issue of the journal The Lancet. In this study from the United Kingdom, nearly 180,000 patients who underwent CT scans as children, between 1985 and 2002, were followed. The incidence of cancer in this very large group of patients was then monitored. In this study, CT scans that delivered a cumulative radiation dose of at least 30 milligray were associated with three times the subsequent risk of leukemia as was observed in patients who received radiation doses less than 5 milligray. The incidence of brain cancer was also three times higher among patients who received a cumulative radiation dose of 50 milligray or more from CT scans, when compared to patients who received less than 5 milligray. Now, it is important to mention that these increases in cancer risk were increases in relative risk. Since both leukemia and brain cancer are rare diseases, the absolute increase in cancer risk was actually quite small (one excess case of leukemia and one excess case of brain cancer per 10,000 CT scans of the head). However, the findings of this important study point out the need to reduce radiation doses associated with CT scans to as low a level as is possible, especially for CT scans performed on children. Moreover, alternative imaging studies to CT scans, such as ultrasound and MRI scans, should be used whenever possible to further reduce the exposure of both pediatric patients and adult patients to medical x-rays.

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.

Kids, Vegetables, Diet, and Rewards

Welcome to Weekly Health UpdateKIDS, VEGETABLES, DIET, AND REWARDS My now 10 year-old daughter used to eat almost everything that we put in front of her when she was a toddler. Lately, however, she has decided that all she wants to eat is macaroni and cheese or mashed potatoes. My now 7 year-old son, on the other hand, spent the years between age 3 and age 5 subsisting largely on “chicken nuggets” and multi-vitamins, and little else…. (The first time that I was able to persuade him to eat some broccoli, at age 5, after suggesting that he dip this much-maligned vegetable in ranch sauce and grated parmesan cheese, I was moved nearly to tears!) Most kids are fussy eaters, and getting your child to eat a healthy, balanced diet can be a serious challenge, if not a perpetual struggle between parent and child. As with most aspects of child-rearing, there are a number of recommended strategies to get Junior to eat his or her vegetables, and other healthy foods. However, many of these strategies turn out to be utterly ineffective in practice. Certainly, one of the most commonly recommended strategies is to offer reluctant young eaters various types of rewards for healthy eating (and which is, in my view, tantamount to bribery, but which has probably been resorted to by most of us parents during times of diet-related desperation, and with varying results). (As I discuss in my bestselling evidence-based book, A Cancer Prevention Guide for the Human Race, fresh vegetables, whole grains, and reduced meat intake have all been associated with a reduced risk of developing both cancer and cardiovascular disease.) Given the never-ending mealtime struggles in our own home, I came across an interesting new research study related to this very topic, and which appears in the current issue of the American Journal of Clinical Nutrition. In this innovative little prospective, randomized, controlled clinical study, 173 children, ages 3 to 4 years, were divided into three groups. All of these children were exposed to vegetables, 12 times per day, that they were known to dislike after these vegetables were first introduced. The first group of children received a tangible reward (a sticker) each time after being served a vegetable that they had initially disliked. The second group of children received praise as a reward upon being served vegetables that they too had disliked upon initial presentation. Finally, a third group (the “control group”) was served vegetables that they had also initially disliked, but this group of children did not receive any rewards (i.e., no stickers and no praise). The findings of this study, while not terribly surprising, offer parents a potential strategy to improve the diets of their (our) vegetable-hating kids. Of course, the children who were repeatedly served disliked vegetables, and who received no stickers or praise, continued to refuse repeated servings of these vegetables. However, the toddlers who were bribed with stickers (a material reward) significantly improved their intake of the offending vegetables over time, and this improvement in vegetable consumption persisted when the children were reevaluated 3 months later. Importantly, the children in this “material reward” group were also significantly more likely to develop a liking for these same vegetables over time! The third group of children, who received praise (a “social” reward) along with each serving of undesired vegetables, sadly, and somewhat unexpectedly, were no more likely to increase their consumption of these vegetables over time, or to develop a liking for these vegetables, than the kids who were in the “no reward” control group! In this clinical study of toddlers, offering children a material reward (stickers, in the case of this clinical study) in conjunction with repeated introductions of initially disliked vegetables resulted in a significant improvement, over time, in the willing consumption of these vegetables, as well as in increased “liking” of these same vegetables. Positive reinforcement through praise was, however, completely ineffective in getting these little tykes to eat (and like) their veggies. In the case of my son, “the vegetable-hater,” the Broccoli Breakthrough occurred on an evening when I took him and his sister out for dinner. In exchange for the privilege of the three of us playing a family card game during our meal, and as a result of my inspired suggestion that he combine two foods that he loved (grated parmesan cheese and ranch dipping sauce) with a food that he hated (the aforementioned broccoli), the miracle of witnessing my little guy downing several florets of broccoli coated in ranch sauce and parmesan cheese finally came to pass. I was so overcome by that moment, two years ago, as was my daughter, that I remember it like it happened yesterday. Moreover, knowing that my wife would almost certainly doubt my incredible claim that this event had actually occurred, I documented this miraculous development with my cell phone camera on the spot, and emailed it to her from the restaurant that night. Nearly two years later, I am happy to report that while both of our kids still challenge us in our ongoing efforts to get them to eat a healthy, balanced diet, our son (and daughter) will still regularly eat that most despised vegetable among children, broccoli!

Cell Phone Use in Children and Teens and Brain Tumor Risk
September 5, 2011 by Robert Wascher

Welcome to Weekly Health UpdateNew 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.
