What are colon polyps?

A colon polyp is a protrusion of the mucous membrane lining the colon. Not all polyps develop into cancer, but larger ones have a 48% chance of becoming cancerous. Polyps need to be confirmed through biopsy and can be removed through colonoscopy, preventing any cancerous development.

When do I need a colonoscopy?

A colonoscopy is only performed when the Fecal Occult Blood Test (FOBT) is positive. A colonoscopy can help detect any polyps or cancer masses in the colon and rectum.

What is the screening process?

The screening process starts with the Fecal Occult Blood Test (FOBT). For FOBT, you will have collect a small sample of your stool prior to appointment date. A container and scoop for the sampling will be provided. It is best to collect the sample on the same day as your appointment so that the stool doesn't dry out.
If the FOBT is positive, meaning that blood was found in the stool, a follow up colonoscopy will be performed.

Is there anything I should know before the test?

You should avoid aspirin and other anti-inflammatory pain relievers for 1 week before taking the Fecal Occult Blood Test (FOBT). If you have any symptoms such as hematuria (bloody urine) or diarrhea, postpone the test until these symptoms have resolved. Additionally, the FOBT should not be performed three days before or after your menstrual period. Be sure to follow the specific instructions provided by the hospital where you have scheduled your appointment to ensure the test is conducted properly.
For a colonoscopy procedure, hospitals use different bowel preparation methods, so adhere to the instructions given by the hospital.

Is there a reason I need to get screened every year?

Colorectal cancer is the third most common cancer for both men and women in South Korea. Survival rate is about 90% for early colorectal cancer, but the survival rate drops to approximately 50% for more advanced stages. Since patients with early colorectal cancer typically experience few symptoms and the cancer grows slowly over time, regular screening is crucial. The South Korean government recommends that all adults over the age of 50 undergo annual screening for colorectal cancer.

What are the early symptoms of colorectal cancer to look out for?

If colorectal cancer is advanced, you might experience changes in bowel habits, such as constipation and diarrhea, as well as bloody stools, indigestion, and weight loss. In the early stages, symptoms are often not noticeable, but you might feel a new lump in your stomach. This is why early detection through regular screening is crucial.
