Maintain A Healthy Weight
A way for an individual to lower their risk of cancer is to maintain a healthy weight or body mass index. Obese individuals have a greater risk of developing several types of cancers than the risk of individuals who are of a healthy weight. These cancers include those of the breast, endometrium, esophagus, colon, rectum, kidney, gallbladder, liver, lymphomas, multiple myeloma, ovaries, prostate, and pancreas. Approximately one-third of all deaths that occur due to cancer are associated with obesity and diet.
An increase in fat deposits around an individual's midsection is also closely correlated with an increased risk of developing cancer. While the mechanisms behind this increased risk of cancer are not clear, they are known to be associated with inflammation, the function of the immune system, hormone levels, activity of insulin-like growth factor-1, and activity of sex hormone-binding globulin. An individual who has a body mass index in the overweight or obese category should reduce their intake of daily calories and burn more calories through regular exercise to maintain a healthy weight.
