Daily Aspirin Use Associated With Reduced Risk of Some Cancers
Researchers from the University of Milan have published a study that suggests that regular aspirin use may reduce the risk of some cancers by up to 35%.
For their study, the researchers reviewed 113 observational studies that looked at the association between aspirin use and the risk of bowel cancer, esophageal cancer, stomach cancer, pancreatic cancer, and head and neck cancer. Regular aspirin use was defined as taking between 75 mg and 325 mg of aspirin daily.
The reduction in risk found for specific types of cancer are:
- Bowel cancer 27%;
- Esophagael cancer 33%
- Stomach cancer 36%;
- Pancreatic cancer 22%;
- Head and neck cancer – no reduction in risk.
The researchers also looked at the effect of aspirin dose on the risk of bowel cancer and found that between 75 and 100 mg daily was associated with a 10% reduction, 325 mg daily was associated with a 35% reduction, and 500 mg daily was associated with a 50% reduction.
The study was published online ahead of print on April 1, 2020 in the journal Annals of Oncology.
