What is Colon Cancer?
Cancer of the large intestine which is the final part of the digestive tumors. It often grows from non-cancerous polyps in the intestine. Both polyps and colon cancers can be found during colonoscopy (camera test of colon). Symptoms can include blood in stool, diarrhea or constipation or both, or abdominal pain but many times there are no symptoms and the cancer is found on colonoscopy. It can be easily treated in early stages, so the general population is encouraged to get screened with colonoscopy and sometimes stool tests. Risk factors include a family history of colon cancer or polyps, or a personal history of abnormal polyps, low-fiber high-fat diets, some inflammatory bowel diseases, diabetes, obesity, and lack of exercise.
Typical Symptoms of Colon Cancer
- Stool has become narrower in caliber, like a pencil
- Blood in stool
- History of abnormal colonoscopy, i.e. colon camera
- Previously diagnosed with Ulcerative Colitis
- Black, shiny stool
- Diagnosed with Crohn's disease in the past
- Constipation with urge to go but unable to pass stool
- Bleeding from the anus
Diagnostic Questions for Colon Cancer
Your doctor may ask these questions to check for this disease:
- Is your stool thin and narrow like a pencil?
- Have you noticed any blood in your stool?
- Have you ever had any issues with a colonoscopy?
- Have you been diagnosed with Ulcerative Colitis?
- Have you had black, shiny stools?
Treatment of Colon Cancer
In most cases a gastroenterologist will diagnose the tumor with a biopsy during colonoscopy or sigmoidoscopy. They will then order CT scans and MRIs and will refer the patient to a colorectal surgeon. A medical oncologist may be consulted to discuss recommendations for chemotherapy before or after surgery and sometimes a radiation oncologist will give radiotherapy to the area. Since the types of treatment can include surgery, radiation, chemotherapy, or a combination of these, it is often important to be treated by a multidisciplinary team, particularly in the case of rectal cancers.
