James Van Der Beek is feeling optimistic after being diagnosed with cancer.

The Dawson's Creek alum, 47, revealed the health update during a recent interview with PEOPLE, where he opened up about his private battle with the disease.

He added, “There’s reason for optimism, and I’m feeling good.”

Representatives for Van Der Beek confirmed his diagnosis for Entertainment Weekly, but did not comment further.

Colorectal cancer, per the American Cancer Society, starts in the colon or the rectum, which together make up the large intestine in the digestive system. Treatment for the diagnosis can include surgery, chemotherapy, and radiation therapy.

While Van Der Beek divulged no further details about his diagnosis, he did celebrate the ongoing support of his family, including wife Kimberly and their six children, Olivia, 14; Joshua, 12; Annabel, 10; Emilia, 8; Gwendolyn, 6; and Jeremiah, 3.

While this is the first instance of Van Der Beek publicly opening up about his diagnosis, he earlier this year announced plans to participate in The Real Full Monty, a two-hour Fox special that will raise awareness for prostate, testicular, and colorectal cancer testing and research — and end with a troupe of male celebrities performing a striptease. Along with Van Der Beek, the cast includes Anthony Anderson (Black-ish), Taye Diggs (All American), Tyler Posey (Teen Wolf), Bruno Tonioli (So You Think You Can Dance?), and the NFL’s Chris Jones.

Aside for disrobing for a dance, the men will also push their limits — physically and emotionally — with a series of curated experiences designed to push them out of their comfort zones. It’s also possible that Van Der Beek will provide further insight into his diagnosis as the group digs deep to "share their personal stories of how cancer has impacted their lives."

In the meantime, the actor is next set to star in Sidelined: The QB and Me, a Tubi original film that hits the service on Nov. 29. He has also continued to prioritize time with his family. Earlier this month, Van Der Beek celebrated son Jeremiah’s third birthday with an emotional Instagram post, writing, "We had no idea how much we needed you. But YOU did. You are once again proof to us that kids come into this world with their own thing; their own essence, appetites, and personality, and you have never been shy about letting us know exactly who you are, and what you want.”

He added, “Thank you for barging your way into our lives. Thank you for all the unique ways in which you challenge me (quite the feat after five kids), and thank you for being the best snuggler on the planet. We love you bubs. Beyond grateful to have those ringlets in my life and to get to be your dad.”
