A colonoscopy is one of those medical procedures that most people know they should have at some point but usually think about having one in some vague feature when they are older. And yet, a colonoscopy is the best way to determine if an individual has or is developing colon cancer鈥攁 devastating illness. For those who don鈥檛 know when to schedule a colonoscopy, doctors have determined a clear list of factors that determine when a person should get one.
The Recommended Age
Most people should get a colonoscopy at age 50. This is true for men and women as there is no difference in rates of colon cancer between genders. Most people have a 5-6% chance of developing colon cancer within their lifetimes.
Exceptions
- Racial disparity: African Americans have higher rates of colon cancer, so doctors recommend a colonoscopy at age 45.
- Family history: You may want to get a colonoscopy earlier than age 50 is you have a family history of colon cancer, as this increases your likelihood of getting the disease.
- Hereditary conditions: There are certain hereditary conditions, such as Lynch Syndrome, that are accompanied by a higher risk of certain cancers, including colon cancer. If you have one of these conditions, early colonoscopies are recommended.
- Troubling symptoms: If you are experiencing bloody stool, especially when accompanied by abdominal pain, it is a good idea to schedule a colonoscopy. Bloody stool is a major red flag and by itself is something to see a doctor about.
The Process
- A colonoscopy takes about 30-60 minutes.
- If no polyps are discovered, you won鈥檛 need another colonoscopy for ten years.
- There is a non-invasive alternative to a colonoscopy known as a stool study that must be conducted every year.
- Those age 75 and older with a polyp-free history do not usually need any more colonoscopies.
