Colorectal cancer - Diagnosis screening and monitoring

Colorectal cancer, also called colon cancer or bowel cancer, includes cancerous growths in the colon, rectum and appendix. It is the third most common form of cancer and the second leading cause of death among cancers in the Western world. Many colorectal cancers are thought to arise from adenomatous polyps in the colon. These mushroom-like growths are usually benign, but some may develop into cancer over time. The majority of the time, the diagnosis of localized colon cancer is through colonoscopy. Therapy is usually th ...

Colorectal cancer - Identification of malignancy. Colorectal cancer can take many years to develop and early detection of colorectal cancer greatly improves the chances of a cure. Therefore, screening for the disease is recommended in individuals who are at increased risk. There are several different tests available for this purpose. Digital rectal exam (DRE): The doctor inserts a lubricated, gloved finger into the rectum to feel for abnormal areas. It only detects tumors large enough to be felt in t ...

Colorectal cancer - TNM or Duke's. Colon cancer staging is an estimate of the condition of a particular cancer for diagnostic and research purposes. The systems for staging colorectal cancers largely depend on the extent of local invasion, the degree of lymph node involvement and whether there is distant metastasis. The most common currently used system for staging is the TNM system, though many doctors still use the older Duke's system. The TNM system assigns a number: T - The degree of invas ...

The treatment depends on the staging of the cancer. When colorectal cancer is caught at early stages (with little spread) it can be curable. However when it is detected at later stages (when distant metastases are present) it is less likely to be curable. Surgery remains the primary treatment while chemotherapy and/or radiotherapy may be recommended depending on the individual patient's staging and other medical factors.

Most colorectal cancers should be preventable, through increased surveillance, improved lifestyle, and, probably, the use of dietary chemopreventive agents. Colorectal cancer - Surveillance. Most colorectal cancer arise from adenomatous polyps. These lesions can be detected and removed during colonoscopy. Studies show this procedure would decrease by > 80% the risk of cancer death, provided it is started by the age of 50, and repeated every 5 or 10 years (Winawer et al 1993). ...

Symptoms of colorectal cancer may include: Change in bowel habits (e.g. constipation, change in the caliber of stools). Blood in stools (melena, hematochezia). Bowel obstruction (rare) by the tumor Often, the symptoms are much less specific: Anemia, with symptoms such as tiredness, malaise, pallor Unexplained weight loss. Hepatomegaly (enlargement of the liver) due to spreading of the tumor It is also possible that there will be no symptoms at all. This is one reason why many organizations recommend periodic screening for the disease wi ...
