Hi. Mucous membranes, or mucosa, are linings of ectodermic origin, covered in epithelium. You can see mucosa at the nostrils, lips, ears, genital area and the anus. The symptoms of colon cancer include diarrhea, abdominal pain, weight loss, blood in the stool, anemia, and intestinal obstruction. Therapy depends on the stage of the cancer. Stage 0 can be treated by cutting out the lesion. For stages I, II and III, surgery is necessary to remove the cancer.
