Rise in Colorectal Cancer Among Young Adults: Houston Methodist West Expert Weighs In
Colorectal cancer, traditionally associated with older adults, is now being diagnosed in younger individuals at an alarming rate. According to the American Cancer Society, the incidence of colorectal cancer in people under 50 has been increasing by 2.4% per year since 2012, while death rates in this group have also been rising by about 1% annually since the mid-2000s.
Dr. Tareq Kamal, a colorectal surgeon at Houston Methodist West, attributes this trend to both lifestyle and genetic factors. “This increase in colorectal cancer is not just about genetics; it’s about the lifestyle choices many of us are making today,” said Dr. Kamal.
What is Colorectal Cancer?
Colorectal cancer begins in the colon or rectum, forming from polyps—small growths on the inner lining of the large intestine. While most polyps are harmless, some can become cancerous over time. If left untreated, cancer cells can spread into blood vessels and lymph nodes, increasing the severity of the disease.
The American Cancer Society estimates that in 2025, there will be 107,320 new cases of colon cancer and 46,950 new cases of rectal cancer in the United States.

Key Risk Factors for Colorectal Cancer
Dr. Kamal highlights several risk factors that may be contributing to the rise in colorectal cancer among younger adults:
-
Dietary Habits: “People are consuming more processed foods and less fiber, which can contribute to a higher risk,” Dr. Kamal explained.
-
Physical Inactivity: A sedentary lifestyle has been linked to an increased likelihood of colorectal cancer.
-
Smoking and Alcohol Use: Tobacco and excessive alcohol consumption can contribute to inflammation and genetic mutations that lead to cancer.
-
Environmental and Genetic Factors: While lifestyle plays a major role, a family history of colorectal cancer significantly raises a person’s risk.
Warning Signs and Symptoms to Watch For
Colorectal cancer symptoms often go unnoticed in the early stages, making screening and early detection critical. Dr. Kamal warns that persistent changes in bowel habits, rectal bleeding, unexplained weight loss, and abdominal painshould never be ignored.
“People often think these symptoms are normal or just a minor issue, but they could be signs of something much more serious,” Dr. Kamal said. “If you’re experiencing any of these symptoms, don’t wait—seek medical attention. A colonoscopy could save your life.”

The American Cancer Society now recommends routine colorectal cancer screenings begin at age 45. However, for those with a family history of colorectal cancer or additional risk factors, screenings may be needed even earlier.
“If colorectal cancer runs in your family, it’s essential to talk to your doctor about your risks and take action early,” said Dr. Kamal. Colonoscopies remain the gold standard for early detection, allowing doctors to identify and remove precancerous polyps before they develop into cancer.
