What is a colonoscopy, and when should it be done?

A colonoscopy is a medical procedure used to examine the interior of the large intestine (colon) and rectum.
It is a crucial diagnostic tool for identifying abnormalities such as polyps, tumors, inflammation, and bleeding.
Typically, a colonoscopy is recommended for individuals over the age of 50 as a routine screening for colorectal cancer, which is one of the most common cancers worldwide.
However, it may be advised earlier for those with a family history of colorectal cancer or symptoms such as persistent abdominal pain, rectal bleeding, chronic diarrhea, or unexplained weight loss.
The procedure involves the insertion of a long, flexible tube equipped with a camera into the rectum, allowing doctors to view the colon's lining.
While the thought of a colonoscopy might be daunting, it is generally safe and can be life-saving by detecting cancer early when it is most treatable.
If you are experiencing symptoms that concern you or if you are due for a screening, it is important to consult with a healthcare provider.
