Treatments & Services
Colonoscopy
An exam where your doctor looks at your large intestine (colon) and rectum using a long, flexible tube with a camera on it. This allows your doctor to find any changes or issues in your colon or rectum, and remove abnormal tissue if necessary.
Flexible sigmoidoscopy
An exam where your doctor looks inside your rectum and lower colon using a narrow tube with a light and camera, called a sigmoidoscope. It helps your doctor find the cause of symptoms like changes in bowel activity, abdominal pain, and anal bleeding. It can also be used to screen for colon and rectal cancer.
