Signs & Symptoms of Colorectal Colon Cancer

Colon-cancer symptoms vary depending on the size and location of the cancer in the large intestine. Many patients have no symptoms in the early stages, according to the Mayo Clinic. It is important to discuss any persistent changes in bowel habits with a physician. Generally accepted guidelines recommend colon-cancer screenings for patients age 50 or older, and perhaps younger for patients with a family history of the disease.

Bowel Habits

• Colon cancer can cause a change in regular bowel function. Diarrhea, constipation or any change in stool consistency that lasts longer than a few weeks should be discussed with a medical professional.

Blood

• Rectal bleeding or blood in the stool is a symptom of colon cancer. Blood can be bright red or a rusty brown.

Pain

• Colon cancer can result in abdominal cramps, gas, bloating or other pain.

Weakness

• Fatigue, weakness and shortness of breath are common complaints of cancer patients.

Weight Loss

• Unexplained weight loss may be an indicator of a serious medical condition, such as colon cancer.
