The incidence of colorectal cancer among younger individuals is on the rise, prompting health care experts to advise lifestyle adjustments. The American Cancer Society (ACS) reported that in 2019, 20% of colorectal cancer diagnoses were in patients under 55, a notable increase from 11% in 1995. This trend shows an annual rise of 1% to 2%.

In 2023, ACS anticipated around 19,550 new colorectal cancer cases and approximately 3,750 deaths in people under age 50. For 2025, the ACS estimates about 107,320 new colon cancer cases and roughly 46,950 rectal cancer cases in the U.S.

Dr. Joseph Bovi from ThedaCare Cancer Care remarked on this growing concern: “We’ve been witnessing this increase in colorectal cancer cases in young people. We know that lifestyle plays a role. This also means people can take steps to reduce their risk of developing the disease.”

Another concerning development is the rising rate of advanced colorectal cancer among those under 50 by about 3% annually. Dr. Bovi emphasized the importance of knowing family history for early screening recommendations: “It’s important to know your family history. This will determine how soon your doctor recommends you begin screening for the disease."

Genetic factors or family history account for about 30% of cases in individuals under age 50 who develop colorectal cancer. Additional risk factors include personal or family history of polyps or certain diseases like Crohn’s or type 2 diabetes, as well as Lynch syndrome.

Routine colonoscopy screenings are recommended starting at age 45 by both the U.S. Preventive Services Task Force and the U.S. Multisociety Task Force on Colorectal Cancer, with earlier screenings suggested for those at higher risk.

Lifestyle-related factors significantly contribute to increasing diagnoses. Dr. Bovi noted: “Though genetics do play a role... most people diagnosed with the disease do not have a family history or genetic factors that would increase their risk.” Factors such as excess body weight, processed meat consumption, high-fat diets, alcohol intake, smoking, and inactivity are influential.

The ACS advises adults to engage in at least 150 minutes of moderate exercise weekly and suggests incorporating strength training along with vigorous activities totaling at least 75 minutes per week.

“Maintaining an adequate level of physical activity reduces your risk...,” said Dr. Bovi while encouraging gradual changes in exercise habits.

Awareness of symptoms such as abdominal pain, rectal bleeding, diarrhea, and iron deficiency anemia is crucial for early detection and treatment options. Dr. Bovi added: “Early diagnosis can help improve outcomes and provide additional options for possible treatment.”
