Colon Cancer Screening
Colorectal cancer, also known as colon cancer, rectal cancer, or bowel cancer, is the development of cancer in the colon or rectum. It arises from the abnormal growth of cells that possess the ability to invade surrounding tissues or spread (metastasize) to other parts of the body. This abnormal growth often begins as polyps, which are benign (non-cancerous) growths on the lining of the colon or rectum. Over time, some polyps can become cancerous. Early detection through screening is crucial for successful treatment.

There are several ways used for
colon cancer screening as :
Several factors contribute to the development of colorectal cancer. Lifestyle choices like smoking and a lack of physical activity significantly increase the risk. Dietary habits also play a major role, with high consumption of red and processed meats, along with alcohol intake, being linked to increased risk. Individuals with inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis, are also at higher risk. Fortunately, colon cancer screening offers a powerful tool for early detection. By identifying polyps and early-stage cancers, screening can enable timely treatment, preventing the cancer from developing or spreading. Regular screenings are crucial as they can significantly reduce the risk of death and suffering associated with colorectal cancer.
01
Stool Test
Polyps in the colon and smaller cancers can cause small amounts of bleeding that cannot be seen with the naked eye. But the blood can often be found in the stool.This method checks your stool for blood.The most common test used is the fecal occult blood test (FOBT). Two other tests are called the fecal immunochemical test (FIT) and stool DNA test (sDNA).
02
Sigmoidoscopy
This test uses a flexible small scope to view the lower part of your colon. Because the test only looks at the last one-third of the large intestine (colon), it may miss some cancers that are higher in the large intestine.Sigmoidoscopy and a stool test should be used together.
03
Colonoscopy
A colonoscopy is similar to a sigmoidoscopy, but the entire colon can be viewed.During a colonoscopy, you receive medicine to make you relaxed and sleepy.Sometimes, CT scans are used as an alternative to a regular colonoscopy. This is called a virtual colonoscopy.
04
Other Tests
Double-contrast barium enema is a special x-ray of the large intestine that looks at the colon and rectum.Capsule endoscopy involves swallowing a small, pill-sized camera.
