In the last decade, overall rates of colorectal cancer have been falling among the general population in the US. However, African Americans are more likely to develop colorectal cancer at younger ages, and to die from it. The reasons for this disparity are unclear, but they are rooted in socioeconomic and racial inequities.
Screening for colorectal cancer can lower mortality, but it varies in effectiveness and is not always possible to perform, so alternatives are needed. Researchers analyzing studies found evidence for regular use of low-dose aspirin, leading the US Preventive Services Task Force to recommend it for some people.
While the incidence of colorectal cancer has declined among older adults, it has increased in people younger than 50. The American Cancer Society now recommends that adults be screened for this condition starting at age 45.
