Colorectal cancer is a common type of cancer in our population. Many patients who have never had a colonoscopy as screening for colon cancer are often diagnosed with a severe stage. Primarily because they feel that they are unlikely to have cancer, or they decide to have the examination only when the abnormal abdominal pain begins to manifest and bleed during defecation.

1. Colorectal cancer is very common in people over the age of 50. Therefore, it is vital to have a screening for colorectal cancer with a colonoscopy every 5 years. However, if you have a close relative diagnosed with colorectal cancer, you should have a colonoscopy screening test at age 40 and repeat the test every 3-5 years.

If you wait for an abnormal sign to appear, such as blood in the stool, bloody diarrhea, constipation, it is likely that you are at high risk.
2. Colonoscopy is a good screening test for colorectal cancer because if a polyp is detected, it can be a factor that causes colorectal cancer, can be treated at an early stage and has a better chance of being completely cured.

3. Although colonoscopy is a screening test for colorectal cancer, it can also be used to diagnose other bowel diseases. Additionally, it is also advisable to have a gastrointestinal endoscopy, especially on the recommendation of your doctor, and to be examined by a specialist who is an expert in endoscopic technology to get an accurate diagnosis and prompt treatment.
