What is colonoscopy screening? 什麼是大腸鏡篩查?
Colonoscopy examination is currently the best method to screen for colorectal cancer. Doctors use a colonoscope, which is a long, thin, flexible instrument with a camera attached to its tip, to assess the inside of the colon. During colonoscopy, doctors can take tissue samples, remove colonic polyps and perform other diagnostic and therapeutic procedures if necessary.
