Colorectal Cancer Incidence Rate Skyrocketing In Young Adults, Study Shows

Per The Oncology Report, a group of researchers led by Dr. Christina E. Bailey, a surgical oncology fellow at the M.D. Anderson Cancer Center in Houston, examined data for 383,241 colorectal cancer patients between 1975 and 2010 and found a significant year-over-year increase in incidences of colorectal cancer in people under 50.

This increase was especially pronounced in people between the ages of 20 and 34.

Using predictive modeling, the researchers estimated this trend could continue to the tune of a 90% increase in colorectal cancer incidence rate for 20- to 34-year-olds between 2010 and 2030. Among 34- to 49-year-olds, the model suggests a more modest 28% increase during the same time period.

Doctors recommend regular colorectal cancer screening starting at age 50, which may explain why incidence rates for those 50 and older actually decreased during the 35-year timeframe used in the study, according to Dr. Bailey. Patients 75 and older saw an especially sharp decrease in colorectal cancer incidence.

Why are young people getting colorectal cancer more frequently?

While presenting the research at the Gastrointestinal Cancer Symposium, Dr. Bailey told The Oncology Report upticks in obesity, physical inactivity and diets high in red meat and fat – factors known to increase colorectal cancer risk – may be to blame.

Dr. Bailey also cited a decrease in misidentification of colorectal cancer as other gastrointestinal diseases as a possible cause, while suggesting further research needed to be done to determine with certainty why so many younger adults are being diagnosed with colorectal cancer
