Risk Varied by Age
In addition to the increases in the 15- to 19-year-old and 20- to 24-year-old groups, the rates in 2020 compared with 1999 showed a
- 68% increase for ages 25 to 29.
- 71% increase for ages 30 to 34.
- 58% increase for ages 35 to 39.
- 45% increase for ages 40 to 44.
“These findings all emphasize the urgent needs for public awareness and personalized screening approaches,” Dr. Mohamed said, “particularly among younger populations who had the most substantial increase in colorectal cancer incidence we observed.”
The US Preventive Services Task Force lowered the recommended age for colorectal cancer screening from 50 to 45 in 2021. Dr. Mohamed suggested more targeted screening for people under 45 at higher risk.
“I think also staying informed about the rising incidence and the latest research and recommendations in terms of colorectal cancer prevention and screening will be really, really helpful.”
