Can a colonoscopy help detect colorectal cancer?

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Colonoscopy is a medical procedure used for both diagnosing and treating colorectal issues, including colorectal cancer, in individuals like yourself. It involves the insertion of a flexible, lighted tube called a colonoscope into the rectum to examine the entire colon (large intestine).

The benefits of a colonoscopy include

1. Early detection: Colonoscopies can detect precancerous growths called adenomas, which may develop into colorectal cancer. Early identification and removal of these growths can prevent cancer development.

1. Treatment: During a colonoscopy, your doctor can remove polyps or small tumors, reducing the risk of cancer progression.

1. Comprehensive examination: Colonoscopies allow for a thorough examination of the entire colon, unlike other diagnostic tests that may only provide a partial view.

Potential risks associated with colonoscopies include:

1. Bleeding: This may occur due to a biopsy or polyp removal.

2. Perforation: A tear in the colon wall is a rare but possible complication.

3. Reaction to sedation: Some individuals may have an adverse reaction to the medications used to help them relax during the procedure.

4. Infection: Although uncommon, an infection can occur after a biopsy or polyp removal.

The colonoscopy process involves the following steps:

1. Preparation: You will need to cleanse your colon using a special diet and laxatives before the procedure to ensure a clear view of the colon lining.

2. Sedation: You will receive sedation to help you relax and minimize discomfort during the procedure.

3. Colonoscope insertion: The colonoscope is gently inserted into the rectum and advanced through the colon while your doctor examines the lining.

4. Biopsy or polyp removal (if necessary): If any abnormal tissue is found, a small sample (biopsy) may be taken, or polyps may be removed during the colonoscopy.

5. Recovery: After the procedure, you will be monitored until the sedation wears off and you can return home.

The American Cancer Society recommends that those over the age of 50, as well as those with a family or personal history of colorectal cancer or adenomas, get screened on a regular basis. The preferred screening procedure may differ depending on individual risk factors and preferences. For people at average risk, a colonoscopy should be performed every ten years, with alternate screening measures such as fecal immunochemical testing (FIT) or sigmoidoscopy paired with FIT every five. I suggest consulting your healthcare practitioner to decide the best screening schedule for you.

I hope this information will help you.
