What You Need to Know About Colon Cancer in Young Adults

Colorectal cancer, which includes colon and rectal cancers, was once thought to be an illness primarily affecting older adults. But it is increasingly being diagnosed in younger individuals. The recent news that actor James Van Der Beek, 48, died after battling colorectal cancer for several months, serves as a reminder of the importance of monitoring gastrointestinal health at all ages.

In the 1990s, colorectal cancer was the fourth-leading cause of cancer deaths in men and women under 50. But the latest data from the American Cancer Society (ACS) has found a striking shift: Colorectal cancer is now the top cause of cancer death in men under 50, and second to only breast cancer for women under 50.

From 2011 to 2019, colorectal cancer incidence rates dropped by about 1 percent each year. But this downward trend is mostly in older adults. In people younger than 55 years of age, rates have been increasing by 1 percent to 2 percent a year since the mid-1990s, states the ACS.

Mr. Van Der Beek, known for his role in "Dawson’s Creek," shared his diagnosis in late 2024 publicly, emphasizing the need for awareness and proactive health management. Clinical studies on colorectal cancer have not discerned all the genetic factors behind early-onset diagnoses.

The Rise of Colorectal Cancer in Young Adults

About 1 in 23 men and 1 in 25 women will be diagnosed with colorectal cancer in their lifetime, according to the ACS.

Overall, factors contributing to this rise include lifestyle changes, dietary habits, and genetic predispositions. As more cases are identified in younger individuals, it becomes crucial to educate this demographic about the risks and symptoms associated with colorectal cancer.

Importance of Monitoring Gastrointestinal Health

Monitoring gastrointestinal health is essential for early detection and effective treatment. Symptoms of colorectal cancer can often be subtle and may include changes in bowel habits, abdominal discomfort, or unexplained weight loss. Regular check-ups and being aware of your body's signals can make a significant difference.

A colonoscopy is the most effective screening tool for colorectal cancer, which includes cancers of the colon or the rectum. depending on where the cancerous cells originate. This procedure allows doctors to examine the lining of the colon and rectum for any abnormalities, such as polyps or tumors, which can develop into cancer over time.

It's not just for older adults; guidelines now suggest that individuals at average risk should begin screening at age 45, while those with a family history of colorectal cancer should start even earlier. Colonoscopies can detect precancerous growths, making them an essential part of preventive healthcare.

Up to one-third of people diagnosed with colorectal cancer before 50 have a family history or genetic predisposition, and should begin screening before age 45 years.
