Around 20 years ago, Katie Couric went on TV while she underwent a colonoscopy. In 2019, Will Smith posted a video blog of his first colonoscopy at age 50.

Bravo for them. They encouraged people to get this potentially lifesaving exam.

Around 16 million colonoscopies are performed in the U.S. each year. That may sound like a lot, but the Centers for Disease Control and Prevention says that three out of every 10 adults ages 50 to 75 are not up-to-date with their colorectal cancer screening, and almost 20% of folks in that age group have never been screened for colorectal cancer.

In 2019, there were 145,000 new cases of colon cancer in the U.S.

So why don't people get colonoscopies? Many are turned off by the preparation process. The good news is there are now options — from the traditional 1 gallon jug of citrus-flavored liquid to smaller individual bottles of liquid and even prep pills.

For the pills, you take a total of 24: 12 the day before (two every 20 minutes with 8 ounces of water) and 12 the day of the procedure. All preps have a strict protocol of what you can eat/drink leading up to your exam, but many folks find the newer versions more palatable.

The goal of the prep is to make sure the doctor can clearly see any precancerous or cancerous polyps and remove them.

Get your first screening at age 45 if you have no risk factors for colon cancer. Then repeat as recommended, depending on what is found and your risk factors.
