Abstract:
Eighty percent of cancers are due to the factors that have been identified and can be potentially controlled. Cancers of the breast, prostate, and colon have received more research attention than other forms of the cancers. It begins to expand into a lump that can invade healthy tissues and spread to other parts of the body. Thirty percent of cancers are caused by tobbaco. Lung cancer is the most obvious example. Cancers of the mouth, throat, kidney, and bladder are also caused by tobacco. Breast cancer is malignant tumor that has developed from cells of the breast. A malignant to or is a group of cancer cells that may invade surrounding tissues or spread (metastasize) to distant areas of the body. The disease occurs almost entirely in women, but men can get it too. The remainder of this document refers only to breast cancer in women. Dietary factors also play a significant role in cancer risk. At least one-third of annual cancer deaths in the U.S and oneforth in Iran are due to dietary factors. A recent review on diet and cancer estimates that up to 80 percent of cancers of the breast are due to dietary factors. The link between diet and cancer is not new. According to a report of Scientific American." cancer is most frequent among those branches of the human race where carnivorous habits prevail." Numerous research studies have shown that cancer is much more common in populations consuming diets rich in fatty foods, particularly meat, and much less common in countries eating diets rich-in grains, vegetables and fruits. One reason is that foods affect the action of hormones in the body. They also affect the strength of the immune system and other factors. While fruits and vegetables contain a variety of vitamins, minerals, antioxidants, and phytochemicals to protect the body, by contrast, recent research shows that animal products contain potentially carcinogenic compounds which may contribute to increased cancer risk, especially breast cancer.
