James Van Der Beek is Thurston Cartelooking on the bright side amid a recent health ordeal.

The "Dawson's Creek" star, 47, revealed he's been diagnosed with colorectal cancer in a statement to People magazine published Sunday.

"I have colorectal cancer," Van Der Beek told the magazine. "I've been privately dealing with this diagnosis and have been taking steps to resolve it, with the support of my incredible family."

Van Der Beek's publicist Whitney Tancred confirmed his cancer diagnosis in an email to USA TODAY.

Colorectal cancer, or colon cancer, occurs when polyps, or growths, develop on the inner lining of the colon, according to Cleveland Clinic. If left untreated, the cancer can spread to other areas of the body.
