On Tuesday, World Cancer Day, the preventability of cancer made big headlines around the world. Here at AICR, we were pleased to see that.
After all, we’ve dedicated ourselves to funding and analyzing research, which shows we can prevent one-third of the most common cancers — over 374,000 U.S. cancer cases every year — by changes to our diet, physical activity and weight.
But you may have seen headlines with different numbers from the World Health Organization (WHO) saying that one half of all cancers are preventable. We heard from some of you who were confused because AICR says we can cut the number of cancers by one third.
So, which is it? How many cancers don’t have to happen: one-third, or one-half? Who’s right, AICR or WHO?
The answer, of course, is that we both are. Continue reading
Evidence is clear that doing at least 150 minutes weekly of moderate physical activity lowers risk for type 2-diabetes. Now, one study shows that even light physical activity may provide some benefit for people at highest risk.
Type 2-diabetes increases risk for several cancers, including those of the liver, colon and endometrium. Both diseases share many risk factors, including insulin resistance.
The study, published in the International Journal of Obesity, included 68 sedentary, overweight and obese adults with pre-diabetes. They were randomly assigned to two groups. Both groups attended two educational sessions at the beginning of the 3 month study, but only one group attended a supervised walking program – 60 minutes, 3 times per week. Continue reading
Research already shows that being active can reduce the risk of developing several cancers. Now comes a study that suggests for men, taking that brisk daily walk after a cancer diagnosis may lengthen your life.
The study was published in the Journal of Physical Activity and Health, and it adds to a growing body of research suggesting that exercise can have significant health benefits for cancer survivors.
“The main take away message is that physical activity improves survival in men with cancer, says I-Min Lee, MD, ScD, an epidemiologist at the Harvard School of Public Health and lead author of the study.
”There have been previous studies, examining survival in breast, prostate, and colorectal cancer patients, showing similar findings. Our study included not only survivors of these cancers, but of other cancers “
For the study, Lee and her colleagues looked at data collected in 1988 from a group of about 1,000 male cancer survivors. On average the men had been diagnosed six years previously – in 1982. In 1988 the men reported on their activity habits. They also answered questions about their weight, smoking habits, alcohol consumption, and what foods they ate. The data was updated five years later. Continue reading
