Colon cancer is a type of cancer that affects the large intestine. The large intestine is located in the lower section of the intestines and connects directly with the rectum. Colon cancer often begins as noncancerous (benign) polyps. Over time, these polyps develop into malignant masses that are given the diagnosis of colon cancer. Treatment for colon cancer depends on the stage of the condition. Removal of polyps is often the first step in early cancer treatments. More invasive treatments include the removal of affected sections of the large intestine, radiation and chemotherapy treatment.
Change in Bowel Movements
Any change in the size, consistency or frequency of bowel movements that are unable to be explained may indicate colon cancer.
Rectal Bleeding/Blood in Stool
Rectal bleeding that is not associated with hemorrhoids is a symptom of colon cancer. As a general rule, bright red blood is considered new and can be a sign of hemorrhoids, whereas darker blood can indicate a more serious problem. Blood in the stool that is darker in color can also be considered a symptom of colon cancer. Any appearance of stool that is the consistency of coffee grounds should be reported to a physician immediately. This can indicate internal bleeding.
Abdominal Discomfort
Discomfort in the abdominal region can be an indication of colon cancer. Frequent cramps, gas, bloating or pain could be related to early stages of colon cancer.
Full Feeling in Rectum
After having a bowel movement, if the feeling that the bowels were not completely emptied or the feeling of a full rectum is present, this can be a symptom of colon cancer. The cancerous masses that are located in the large intestine when a patient has colon cancer can make them to feel as if the colon is still holding stool.
Weakness/Fatigue
Colon cancer, just like any other type of cancer, causes a decrease in the energy level of the patient. The inability to complete daily tasks due to the fatigue that accompanies colon cancer is often the first symptom that something is wrong.
Unexplained Weight Loss
Any sudden weight loss that cannot be explained due to diet or exercise can indicate a serious problem such as colon cancer. Make a note of the amount of weight loss and check all possible reasons why weight loss may have occurred. If the patient is unable to associate the weight loss with life circumstances such as stress, diet, exercise or change in jobs, he should contact his doctor for testing.
