Not to hijack the thread, but I speak from experience. For those that don't know me or my battle with cancer. I was diagnosed with colon cancer in 2010. Surgery and chemo. Spread to pelvis. Several more surgeries. Then it spread to all lobes of the lungs. Can't do surgery or radiation, only chemo. Chemo makes me very sick but with it I get hopefully a few more years. Without chemo only a year or so. I've had 5 major abdominal surgeries and constant surgery since initial diagnosis. I have a 15" scar that causes constant pain. I think you get my point. Colon cancer is one of the more aggressive ones. As they say on TV get this one done!
