A polyp removed from Joe Biden's intestine during a colonoscopy last week turned out to be benign, but it could be pre-cancerous.

The 79-year-old president underwent a colonoscopy at Walter Reed Army Medical Center in Maryland last week, after experiencing loose bowels and excessive flatulence.

Biden was placed under anesthesia and a flexible tube with a camera attached was snaked into his rectum, large intestine and small intestine.

His doctor performed a colonoscopy procedure to inspect the intestinal walls for polyps or cancerous lesions.

Dr. Kevin C. O'Connor, physician to the president, said the polyp could be pre-cancerous but it was removed and requires no further action.

A follow-up colonoscopy will be conducted in 7-10 years, the doctor wrote in a memo.

Dr. O'Connor insists Biden is "fit for duty," but the president is showing some signs of aging.

While he was under, Vice President Kamala Harris assumed the powers and duties of the president for approximately 90 minutes.

Most polyps are harmless growths or clumps of cells on the intestine wall. They are also found in the uterus, cervix, stomach, ear, nose, bladder, and throat.

Polyps become dangerous when they develop into colon cancer or uterine cancer.

"The best prevention for colon cancer is regular screening for and removal of polyps," the Mayo clinic advises on its website.

Other preventions include eating less meat or no meat, taking an Aspirin a day, and eating a calcium-rich diet.

Harris was president for a few short hours this morning. The White House announced the procedure just before noon. Biden resumed the presidency about an hour later.

American rap producer Swizz Beatz is urging men to get a colonoscopy to check for cancerous polyps in the colon. The 39-year-old father of 5, whose real name is Kasseem Dean, posted an Instagram.com image of himself lying on a hospital gurney after undergoing a colonoscopy.

He told his Instagram followers he fulfilled a promise he made to a friend who died of colon cancer.

Swizz captioned the photo in part:

"Today I did a Colonoscopy, which many men refuse to do until it’s too late. It only took 2days for the entire process and thank God I’m okay. I wasn’t going to share this but I promised my brother I would spread the word to prevent others from going through what he did Blessings to all. Your health is your wealth... F@ck Cancer...."
