Final answer:
A colonoscopy is an essential medical procedure to detect colorectal conditions, needing proper bowel preparation for effectiveness. It involves the removal of polyps to prevent colorectal cancer (option a. True).
Explanation:
The colonoscopy is an examination of the inside of the colon using a colonoscope, which is inserted into the rectum. This procedure is vital for detecting colorectal conditions, such as colorectal cancer, which can present symptoms like constipation, cramping, abdominal pain, and rectal bleeding.
Benign mucosal growths known as polyps can develop into colon cancer; thus, early identification and removal during a colonoscopy are key preventive measures.
Bowel preparation is critical for a successful colonoscopy, as inadequate preparation can limit the visibility of the ascending colon, potentially missing polyps or other abnormalities. Regular screening is typically recommended for individuals over the age of 50.
