Colon cancer does NOT develop with a single genetic mistake from normal to full blown cancer like many others (breast, prostate). The process usually takes an average of 12 years. From stage to stage is probably a couple of years, The recent hullaballoo at the VA demonstrated that even a one year wait may not matter! ...Read moreSee 2 more doctor answers
Maybe: Colon cancer is dangerous unless treated and surgically removed, and can spread to lymph nodes or other organs such as the liver.
