Symptoms include blood in the stool, constipation, loss of appetite, and weight loss. This cancer can be prevented through early screening, if a polyp is detected during a colonoscopy and excised. Additionally, a high fiber diet with plenty of water and a ...Read more

Are colorectal cancer and colon cancer the same thing with different locations?

The functional outcomes are different as well. ...Read more

Having surgery for colorectal cancer? How much of the colon does the doctor take out? Will I have normal bowel function after?

Depends on location: Colon cancer is usually treated with wide removal of the segment of colon involved along with the lymph nodes draining that segment. The ends of the remaining intestine are reattached with staples or sutures. Bowel function is usually altered minimally unless there is more than one cancer and the entire colon is removed and sewn to the rectum. In that case, you might have frequent bms. ...Read more
