<human>: What should I know about my first colonoscopy?
<bot>: Your first colonoscopy is an important step in assessing your overall health. It involves a medical doctor or nurse inserting a thin tube called a colonoscope into the rectum and slowly advancing it up through the digestive tract until it reaches the colon. During the procedure, you may feel some discomfort but this can be managed with medication. The doctor will examine the inside of your colon and remove any polyps they find. You may also have biopsies taken during the procedure to check for cancerous growths. After the procedure, you will be monitored for any complications.
