Colorectal cancer usually starts from the colon or from the rectum. This is the third most common type of cancer which is caused by men and women. Given below are some of the most important questions that you must know about.
Importance of Colorectal screening
Many types of cancers can be avoided through regular screening. In screening, many types of precancerous polyps, any kind of abnormal growth in the rectum of the colon can be observed and thus it can be treated. Screening is very important because, if we find a kind of issue there are higher chances of successful treatment. In the early stages, colorectal cancer doesn’t show any kind of symptoms and it starts to appear as cancer grows. It is highly recommended that people should start screening from the age of 45.
What is a colonoscopy?
This is one of the best screening tests for colorectal cancer. This is the only test that prevents many types of colorectal cancers. Given below are a few things that you must know about this test.
During the screening, the doctor examines the inner lining of the colon and if there are any polyps or tumors, the doctor will remove the same immediately.
On the day of the colonoscopy, the doctor will give you medication that will help you to relax. It may happen that you may fall asleep and you won’t even remember anything about the screening.
Doctors perform the colonoscopy by inserting a thin, long tube which is called a colonoscope into the colon via the rectum. The tube also contains a small video camera and a light that will send images to the screen where the doctor will see and analyze the colon.
Before starting the procedure, the doctor will give you instructions about what to eat and what not to eat.
If you are at the age of 50, then you must start having a regular screening of colon because this is the age that is at high risk of having colon cancer. It’s better to consult your doctor about this. The doctor will inform you about the schedule for such tests.
What about other screening tests?
If you are unsure about the colonoscopy then the doctor will recommend the following tests
- Double-contrast barium enema
- Virtual colonoscopy
- A fecal occult blood test
- DNA stool test
Let us inform you that, these tests are not as effective as colonoscopy. If you have got polyps or tumors inside based on these tests, still you will need to have a colonoscopy.
