Colorectal cancer, also called colon cancer, rectal cancer or bowel cancer almost always occurs in the large bowel - cancer of the small bowel is rare. Symptoms of colorectal cancer include blood in your stools, a change in normal bowel habits, a lump that your doctor can feel in your back passage, weight loss, pain in the abdomen or back passage, and anemia. Treatment depends on where the cancer is in the bowel and how far it has spread but may include surgery, chemotherapy and radiation.
