Daily Low-Dose Aspirin May Decrease Cancer Risk for Some Adults, Study Suggests

Daily Low-Dose Aspirin and Cancer Risk

A study published in JAMA Oncology suggests that daily low-dose aspirin may decrease cancer risk for some adults.

According to the research, Clonal Hematopoiesis of Indeterminate Potential (CHIP) at a Variant Allele Frequency (VAF) of 10% or greater is the strongest predictor of whether daily low-dose aspirin can help prevent cancer in healthy, older adults.

CHIP is the strongest predictor of whether daily low-dose aspirin could help prevent cancer in healthy, older adults.

The study was a non-prespecified secondary analysis of the randomized Aspirin in Reducing Events in the Elderly (ASPREE) trial and the ASPREE-CHIP substudy, which found no difference in cancer incidence among participants who received 100 mg of daily aspirin compared to placebo.

However, the effectiveness of daily low-dose aspirin in reducing cancer risk varied widely across the study cohort, indicating that personalized treatment approaches would be beneficial.

Author's summary: Aspirin may reduce cancer risk in some adults.
