Physical activities can reduce risk of cancer


A healthy diet and physical activities can help in reducing overall cancer risk, especially lowering breast, prostate and colorectal cancer risks.
Researchers at the American Association for Cancer Research analysed the nutritional scores which showed the biggest benefit from a diet that reduces the risk of cancer.
The researchers estimated that in developed countries, around 35 per cent of breast cancers and 45 per cent of colorectal cancers could be avoided by better adherence to nutritional recommendations. It is, therefore, very important to investigate the role of nutrition in cancer prevention.
This study evaluated three previously validated nutritional recommendations: The WCRF/AICR score; the Alternate Healthy Eating Index; and the French Nutrition and Health Program-Guidelines Score, plus one relatively new index, the MEDI-LITE score, which measures adherence to a Mediterranean diet.
Researchers found that all the diets were associated with some reduced risk, but the WCRF/AICR recommendations, developed specifically with cancer prevention in mind, had the strongest association with reduced risk.
Between May 2009 and January 1, 2017, 1,489 cancer cases were diagnosed in the study participants, including 488 breast cancers, 222 prostate cancers, and 118 colorectal cancers.
The researchers used multivariable Cox proportional hazard models to characterize the associations between each nutritional score and cancer risk, according to the findings appeared in the Journal of Cancer Research.
The study showed that a one-point increase in the WCRF/AICR score was associated with a 12 per cent decrease in overall cancer risk; a 14 per cent decrease in breast cancer risk, and a 12 per cent decrease in prostate cancer risk.
Adherence to the other diets was also associated with reduced cancer risk, but the WCRF/AICR index demonstrated greater statistical strength and a better predictive performance, researcher said.
For that reason, and because the other three diets were not specifically designed for cancer prevention, the researchers conducted further analysis on the WCRF/AICR scores, excluding certain components to evaluate the relative importance of each one.
Even moderate activity can be critically important in helping menopausal women reduce their risk of cancer, heart disease and other chronic ailments.
Exercise reduces fat deep in the abdomen (“intra-abdominal” fat), a hidden risk factor because it can raise insulin levels, which promote the growth of cancer cells as well as cholesterol levels. Most American women gain 1 to 2 pounds on average every year, and that adds up to dangerous levels over a lifetime.
