Colon cancer is the third most commonly diagnosed cancer among American men and women and the third leading cause of cancer death. According to the American Cancer Society, about 98,200 cases will be diagnosed in the U.S. this year and 48,100 people will die from it. Colon cancer is more common after age 50, in people with a family history of the cancer, patients with chronic inflammatory bowel disease, and those who are obese, inactive, or have a high fat diet.
Most colon cancers develop from tiny growths known as adenomatous polyps, or adenomas.
Although these polyps are not cancerous themselves, having them increases the chance of developing the cancer. Therefore, doctors often recommend removal of the polyps if they're found during routine screenings. Researchers are also looking at diet as a way to fight cancer. Some studies suggest increasing calcium intake may help reduce the risk of colon cancer. But dairy products, which are high in calcium, are also high in fat, and could increase the risk for other cancers and cardiovascular problems.
