Colon and rectal cancer
At the age of 50, every individual is advised to get a colonoscopy once every ten years. There are other options to this, but if anything comes back positive, you can get a colonoscopy anyway, so colonoscopies are preferable. These options are: get a CT colonography every five years, get a flexible sigmoidoscopy [1] every five years, get a stool DNA every five years, do a fecal immunochemical screening [2] every year, or a guaiac-based fecal blood test and get a double-contrast barium enema [3] every five years. It is essential to do these tests at a registered cancer hospital.
