Describe the life style cancer / behaviour and explain 5 factors that contribute to the cancer
Eighty percent of cancers are due to factors that have been identified and can potentially be controlled, according to the National Cancer Institute. [ And not only can we potentially prevent most cancers, we can also improve the survival rates of people who have cancer. Cancers of the breast, prostate, and colon have received more research attention than other forms of the disease, but, as we
will see, certain principles apply to many forms of cancer.
Cancer starts when one cell begins to multiply out of control. It begins to expand into a lump that can invade healthy tissues and spread to other parts of the body. But there is a lot we can do about it. Thirty percent of cancers are caused by tobacco. Lung cancer is the most obvious example, but by no means the only one. Cancers of the mouth, throat, kidney, and bladder are also caused by tobacco.
Dietary factors also play a significant role in cancer risk. At least one-third of annual cancer deaths in the U.S. are due to dietary factors.1 A recent review on diet and cancer estimates that up to 80 percent of cancers of the large bowel, breast, and prostate are due to dietary factors. ]
