Staying at a healthy weight, eating clean, and exercising daily are not only good for you, but they also prevent cancer.
The American Cancer Society and the top Cancer Hospitals recommend the Mediterranean Diet, a plant-based diet. As a cancer survivor, I also highly recommend this.
There are many great articles on this subject, but here's a taste of one.
New evidence on how weight, diet and exercise can help reduce cancer risk
Washington Post -
Cutting your risk of cancer is no longer just about shunning tobacco. Be lean. Eat healthfully. Get active. Common-sense lifestyle strategies for lowering the risk of heart disease and diabetes are now being shown to help prevent many types of cancer.
Of course, there are few absolutes in cancer prevention. Cancer is still a riddle, with many factors, including genetics, playing a role. But growing evidence suggests that there are steps that we can take to lower our chances of getting the disease, experts say.
Otis Brawley, chief medical officer for the American Cancer Society, urges careful attention to the “three-legged stool” of excess weight, poor diet and inadequate physical activity, which together are linked to between a quarter to a third of cancer cases. If tobacco use continues its decline of the past 15 years or so, he said, that trio may supplant smoking as the leading preventable cause of cancer.
Indeed, a recent study found that women who followed the ACS Guidelines on Nutrition and Physical Activity for Cancer Prevention lowered their risk significantly. Those guidelines include maintaining a healthy weight, adopting a physically active lifestyle, consuming a healthful diet that emphasizes plant-based food, and limiting alcohol intake. Data on more than 65,000 post-menopausal women tracked for more than 12 years found that compared with those who were least compliant with the ACS guidelines, the women who followed them most closely had a 17 percent lower risk of any cancer, a 22 percent lower risk of breast cancer and a 52 percent lower risk of colorectal cancer, according to a study released in January.
“This suggests that even later in life, if you are making healthy choices it seems to be protective in terms of cancer risk,” said lead author Cynthia Thomson, a professor in the college of public health at the University of Arizona. The women who best adhered to the guidelines were also 27 percent less likely to have died during the time frame of the study.
