Colon cancer occurs in the large intestine, which is also known as the colon. The colon is located in the lower area of the digestive system. Colon cancer often starts off as benign polyps but over time these polyps turn in to cancer. Diagnosing colon cancer in the earliest stages is imperative to survival.SymptomsMany people experience no symptoms with colon cancer in the earliest stages. When symptoms do arise, they often present at varying degrees depending on the location and size of the cancer. The most common symptoms of colon cancer are fatigue or weakness, sudden weight loss, the feeling that the bowel does not completely empty, blood in the stool or rectal bleeding, persistent discomfort in the abdomen such as gas, pain or cramps, and changes in normal bowel habits like constipation or diarrhea. It's important to note that these symptoms are quite general and are often the sign of another medical condition that is not colon cancer. It's important, however, to talk with your doctor if you experience the symptoms of colon cancer. Risk FactorsAlthough colon cancer can affect a person of any gender, race or age it is more common in those that exhibit certain risk factors. People over the age of 50 are more likely to develop colon cancer as are African-Americans and those with a family history of colon cancer, polyps or inflammatory intestinal conditions. Other risk factors include obesity, Diabetes, a sedentary lifestyle, a low-fiber and high-fat diet, smoking and heavy alcohol consumption. TreatmentOnce a diagnosis of colon cancer is made, different treatment options are available based on the stage and progression of the cancer. Surgery is available for early-stage, invasive and advanced colon cancer. Other treatment options include chemotherapy, radiation therapy and targeted drug therapy. A combination of treatments may be necessary to effectively remove all of the cancer. PreventionAlthough the exact causes of colon cancer are unknown, there are some things you can do to lower your risk. If you have an increased risk of colon cancer or if you are African-American or American Indian, start getting screened at age 45. Those with an average risk should begin screening at age 50. Eating plenty of whole grains, fruits and vegetables may help to prevent colon cancer. If you drink alcohol, do so in moderation. Aim for 30 minutes of exercise each day and maintain a healthy weight. Finally, stop smoking to also help lower your risk of developing colon cancer.
