- Stool-based tests – For stool-based tests, a fecal sample is collected and tested for signs of cancer. These tests are not as invasive and are easier to have done than other tests, but they have to be done more regularly. There are options to collect the sample from the comfort of your own home and then send to a lab for testing.
- Visual exams – A colonoscopy is perhaps the most commonly known example of a visual exam. Visual exams are tests that look at the structure of the colon and rectum for anything irregular. To perform this test, which can take about 30 minutes or a little longer, the colon and rectum must be empty and clean. If anything abnormal is found, the physician will likely take a sample to test. A sedative is used to help keep you comfortable during the test, so you may need someone to help drive you home and get you settled afterward.
