Colon cancer, also called colorectal cancer, is the second leading cause of cancer-related death for men and women in the United States, according to the American Cancer Society. Cancerous cell growth within the lining of the colon or large intestine can cause painful symptoms in affected people. If such symptoms arise, people should seek care from a medical professional.
Abdominal Pain
Abdominal pain is one of the most frequently reported symptoms associated with colon cancer. When cancer cells grow along the colon, they can inflame and irritate this digestive tract tissue, leading to sensations of abdominal pain or discomfort. In addition to pain, people with colon cancer may experience sensations of bloating or cramping in the abdomen, MayoClinic.com warns.
Painful Bowel Movements
Painful or difficult bowel movements, also called constipation, may occur as a symptom of colon cancer, the Merck Manuals Online Medical Library explains. Cancerous cells that cluster together in the intestinal tract can interfere with the normal flow of ingested food products through the digestive tract. Consequently, people may experience pain, discomfort or difficulty producing a normal bowel movement. Constipation may also occur in conjunction with abdominal pain, cramping or bloating.
Additional Symptoms
Additional colon cancer symptoms include diarrhea, bloody or narrow stools, increased fatigue, nausea or vomiting, according to the National Cancer Institute. In combination, these symptoms may result in appetite loss and unintended weight loss in people with this form of cancer. These symptoms of colon cancer may also be signs of alternate medical problems, including an infection or stomach ulcer. People who experience any of these uncomfortable colon cancer symptoms should consult a doctor for further evaluation and care.
