The recent passing of actor James Van Der Beek at age 48, following a battle with stage 3 colorectal cancer, has brought renewed attention to a disease increasingly diagnosed in younger adults. While colorectal cancer remains the third most common cancer worldwide and the second leading cause of cancer-related deaths, according to the World Health Organization, advancements in screening and treatment offer hope for early detection and improved outcomes. Understanding the risk factors, recognizing potential symptoms, and embracing preventative measures are crucial steps in safeguarding your health.
Colorectal cancer, encompassing cancers of the colon and rectum, is often a gradual-growing disease. Early detection is paramount, as “This represents a curable cancer if diagnosed early,” emphasizes Dr. Deirdre Cohen, director of the gastrointestinal oncology program for the Mount Sinai health system and an associate professor of medicine. The rise in cases among individuals under 50 is particularly concerning, prompting a reevaluation of screening guidelines and a deeper look into potential environmental factors.
What is Colorectal Cancer?
Colorectal cancer develops in the large intestine. The colon and rectum, while distinct, function together in the digestive process, with the rectum positioned at the finish of the colon. Cancer can originate in either location, and in some instances, affect both simultaneously, explains Dr. Derek Ebner, a gastroenterologist at Mayo Clinic in Rochester, Minnesota. The disease often begins as non-cancerous polyps that, over time, can transform into malignant growths.
Can Colorectal Cancer Be Prevented?
While a guaranteed prevention isn’t possible, lifestyle choices can significantly reduce your risk. Avoiding smoking and limiting alcohol consumption are key preventative measures, according to Dr. Cohen. Diet plays a crucial role, with an emphasis on a diet rich in fruits and vegetables and limiting processed meats like hot dogs and bacon. The American Cancer Society highlights a link between high red meat consumption and an increased risk, with a 2024 study in Cancer Epidemiology, Biomarkers & Prevention finding a 30% increased risk for those with the highest intake of red meat and a 40% increased risk for those consuming the most processed meats.
Beyond diet, incorporating lean proteins, high-fiber foods, and embracing a dietary pattern like the Mediterranean diet are recommended by Dr. Ebner. Regular exercise is as well critical, with a 2025 study published in the New England Journal of Medicine demonstrating that a three-year structured exercise program led to “significantly longer disease-free survival” and overall survival.
Rising Rates and the Importance of Screening
colorectal cancer rates are declining, largely due to increased screening efforts. However, a concerning trend is emerging: a “striking…astronomical rise” in cases among those under 50, as noted by Dr. Cohen. The American Cancer Society reports that rates have increased by approximately 3% annually since 2010 for individuals under 50, with death rates increasing by 1% annually since 2005. The reasons behind this increase are still under investigation, with potential links to ultra-processed foods, sugary beverages, and processed meats.
The US Preventive Services Task Force recommends that screening begin at age 45 for most individuals. However, roughly one-third of eligible individuals are not currently undergoing screening, according to Dr. Ebner. Screening methods include colonoscopies, stool-based tests, and blood-based tests, each with its own benefits and limitations. A colonoscopy, performed every 10 years with normal results, remains the most comprehensive option, allowing for the simultaneous identification and removal of precancerous polyps.
Recognizing the Symptoms
Colorectal cancer can be asymptomatic in its early stages, underscoring the importance of regular screening. When symptoms do appear, they can include blood in the stool, changes in bowel habits (such as frequent or prolonged constipation or diarrhea), unexplained weight loss, or persistent abdominal pain, according to Dr. Cohen. It’s important to discuss any concerning symptoms with a healthcare provider, even if they feel embarrassing, as early detection significantly improves treatment outcomes.
What Does the Future Hold?
The increasing incidence of colorectal cancer in younger adults highlights the necessitate for continued research into the underlying causes and the optimization of screening strategies. Further investigation into the role of diet, lifestyle, and environmental factors will be crucial in developing more effective prevention methods. Advancements in treatment continue to offer hope for those diagnosed, emphasizing the importance of early detection and access to quality care.
