Colon, or colorectal, cancer is one of the leading causes of cancer related death in the United States, according to the American Cancer Society. No single cause for colon cancer is known, but the National Institutes of Health says that almost all colon cancer begins as noncancerous polyps, which can turn into cancer if not removed. At age 50, all women should begin getting a colonoscopy regularly to help screen and detect any possible colon polyps and cancer.
Abdominal Pain
Abdominal pain, generalized in the lower abdomen area, is a symptom of colon cancer, according to the National Institutes of Health. The pain may radiate throughout the abdomen. An intestinal blockage related to a cancerous tumor may be to blame, or excess cramping and gas could be the cause. The pain may also be accompanied by abdominal tenderness.
Bowel Habit Change
Some people who have colon cancer have a change in bowel habits for a few weeks or more, according to the Mayo Clinic. Excess diarrhea, constipation or both may occur. The stool may also change consistency and may be accompanied with blood from the rectum or stool. The stool may also be more narrow if part of the intestines is blocked.
Malabsorption
Diarrhea may cause some food to not be digested properly, causing unexpected weight loss, according to the Mayo Clinic. Low intake may also occur if other symptoms are present, which may promote weight loss. Anemia may also occur with low intake and malabsorption, especially if blood is lost in the stool, causing symptoms such as weakness and fatigue.
