Rising colorectal cancer in younger adults

Overview

Medical research indicates a significant rise in colorectal cancer rates among adults under the age of 50. Globally, approximately 10% of diagnoses now occur in this younger demographic, with projections suggesting substantial increases in incidence rates for those aged 20–49 by 2030.

In the United States, colorectal cancer has become the leading cause of cancer death for men under 50 and the second leading cause for women in the same age group. Recent data highlights a broader epidemiological shift; an international study in BMJ Oncology reported a 79.1% increase in early-onset cancers between 1990 and 2019, encompassing colorectal, thyroid, liver, kidney, pancreas, endometrial, breast, and ovarian cancers.

Research suggests that colorectal cancer in younger patients may possess distinct genetic and biological characteristics compared to older patients, potentially requiring different treatment approaches. In Australia, studies indicate early-onset cases often involve tumors in the left side of the colon and frequently present in women.

Studies suggest the trend is driven by a ‘birth cohort effect’ rather than genetics, potentially linked to sedentary lifestyles, obesity, smoking, and alcohol consumption. A primary contributing factor is the consumption of ultra-processed foods, including processed meats and sugary beverages. Experts also note challenges in prevention, such as a rising proportion of women aged 21 to 29 in the U.S. who have never undergone cervical cancer screening.
