I was wondering what are the signs/symptoms of lower bowel/rectal cancer?

See below. Often there are no symptoms in early stages. Signs and symptoms include bleeding, change in bowel habits, occult blood in stool, abdominal pain, intestinal obstruction, anemia and if metastases develop, jaundice and abdominal swelling. See this site for more info. Http://www. Mayoclinic. Org/diseases-conditions/rectal-cancer/basics/definition/con-20036554.
