This is totally false. The number one risk factor for colon cancer is age not family history. It s extremely rare under age 35. People who do have positive family histories are at even higher risk for having colon polyps and developing colon cancer. I feel just fine.
Colon cancer comes from precancerous growths in the colon called polyps.
Polyps don t cause any symptoms until they are very large or have turned into colon cancer itself. By then its usually too late. You usually don t get symptoms until you have colon cancer. Most colon cancers are diagnosed early before they have spread outside the colon and are curable. This shortens your life span considerably even with surgery, if indicated, chemotherapy.
