Sigmoidoscopy: Essential Colorectal Cancer Screening for Adults Over 50
A sigmoidoscopy, a procedure to examine the sigmoid colon, is often recommended for adults over 50 as part of colorectal cancer screening. It can detect early signs of cancer and other conditions. However, it's also used when there are changes in bowel habits, rectal bleeding, abdominal pain, or unexplained weight loss.
The procedure involves inserting a thin, flexible tube with a light and camera into the anus to examine the colon. During this time, tissue samples may be taken for further examination, and polyps or growths may be removed. Preparation involves using enemas and following a clear liquid diet for one to three days beforehand.
Risks include tears in the colon or rectum and bleeding where tissue samples were taken. After the procedure, some bloating or cramping is normal, but severe pain, dizziness, bloody stool, or fever should be reported to a doctor immediately.
Sigmoidoscopies are a crucial tool in detecting and preventing colorectal cancer. They are typically recommended every five years after the age of 50, or sooner if certain symptoms or risk factors are present. If you're over 50 or experiencing concerning symptoms, consult your healthcare provider about this procedure.
