Colorectal Cancer Prevention

Colorectal Cancer Prevention

Colorectal cancer patients  seem be getting younger and younger. Patients between the age of 40 to 50 has tripled in the past 20 years.  60% of colorectal cancer occurred in the last two feet of the large intestine - the sigmoid colon to the rectum.  In fact, colorectal cancer is usually caused by intestinal polyps. The key to prevention is early detection and removal of intestinal polyps, so to prevent it from developing into malignant colorectal polyps.

Both men and women should have regular check-ups once reached the age of 50.  Here are some options:

Option 1- Fecal Occult Blood Test

The most basic method  is to receive annual FOBT (Fecal occult blood test), which is a test to see if stool contains  invisible blood.  If the test is positive, further procedure, such as colonoscapy, needs to be done.

Option 2- Sigmoidoscopy

Conduct sigmoidoscopy once every five years.  Endoscopic length is short, only up to the sigmoid colon.

Option 3- Fecal Occult Blood Test + Sigmoidoscopy

FOBT annually AND sigmoidoscopy once every five years.

Option 4- Colonoscopy

Colonoscopy once every five years, which can reach the entire colon.

Generally speaking, people with family history of colorectal cancer or intestinal polyps previously found are at high risk group.  This group should begin regular check-ups at a younger age, and procedures should be done more frequently. If polyps are found during the colonoscopy procedure, doctors can remove them immediately.
