Warfarin may protect against common cancers

Observational study finds 16% reduced risk of common malignancies

Warfarin may protect against common cancers, an observational study suggests.


The population-based study of more than 1.2 million over-50s shows a “remarkable association” between warfarin use and lower cancer incidence, say the researchers from Norway.

Their review, based on national registry data over a seven-year period, found that warfarin users had a 16% reduced risk of all cancers after a minimum two-year interval, compared with non-users.

Looking at organ-specific sites, warfarin use was linked with a 31% reduced risk of prostate cancer, a 20% reduced risk of lung
