James van der Beek thought his body was in peak condition. He was exercising, doing cold plunges, and felt healthy. But a small change in his bowel habits—something he brushed off as a side effect of coffee—turned out to be the first sign of stage 3 colorectal cancer.
The “Dawson’s Creek” star, now 48, shared his story to raise awareness about a disease that often develops quietly and goes unnoticed until it’s advanced. Here, we’ll look at what he experienced, why colorectal cancer is on the rise in younger adults, and what doctors say are the red flags you shouldn’t ignore.
The symptom that didn’t seem alarming before the diagnosis
Before his diagnosis in late 2024, van der Beek told Healthline there wasn’t “any red flag or something glaring”. He felt strong and had no obvious reason to suspect cancer. The only change he noticed was in his bowel movements. Believing it was linked to his daily coffee routine, he didn’t give it much thought.
That changed after he went in for a colonoscopy. The screening revealed stage 3 colon cancer, a diagnosis that came as a shock given his age, health, and active lifestyle. “I was in amazing cardiovascular shape, and I had stage 3 cancer, and I had no idea”, he said.
Doctors note his story is not unusual. Colorectal cancer often develops silently, without obvious symptoms. By the time patients feel unwell, the disease may already be advanced. This makes paying attention to even subtle changes—like shifts in bowel habits—an important part of early detection.
What doctors want you to know
Experts stress that changes in bowel movements should not be ignored, especially if they persist. According to oncologist Eitan Friedman, other warning signs include blood in the stool, unexplained fatigue, anemia, abdominal discomfort, loss of appetite, and unintended weight loss. These symptoms, while not always caused by cancer, warrant medical attention.
The risk of colorectal cancer increases with age, but doctors are seeing more cases in younger adults. The American Cancer Society now recommends regular colonoscopies starting at 45, down from the previous guideline of 50. Screenings every five to 10 years can detect polyps before they become malignant and allow for their removal.
Family history also matters. People with a first-degree relative who has had colon cancer, or those with conditions like ulcerative colitis or Crohn’s disease, face a higher risk. For these groups, earlier and more frequent screenings may be necessary.
Despite the effectiveness of colonoscopy, screening rates in the U.S. remain lower than national goals. Rural, low-income, and minority communities are disproportionately affected by these gaps. Physicians like Erica Barnell, a physician-scientist at Washington University, emphasize the need for broader access to noninvasive screening options and better public awareness.
Colorectal cancer carries a lifetime risk of about 4% to 5% for the average person, but many cases are preventable with early detection. Van der Beek’s experience highlights how easy it is to dismiss small changes and how dangerous that can be. “Most people don’t like talking about bowel habits, but paying attention to changes can save your life”, Barnell said.
