“Overall risk of dying from cancer was reduced by 16% among people who took daily dose of aspirin when healthy“
Hmm… RR 0.84 for those taking aspirin prophylactically. RR <0.5 might be something but a null result even on 100K patients isn’t really compelling given they had no history history of cancer nor obvious risks. What non-cancer morbidities did these people suffer? Were they exacerbated by this prophylactic treatment?
Taking a low dose of aspirin every day may reduce the risk of cancer and slow the spread of the disease, according to a study that followed the health of more than 100,000 patients.
Research by a team at the American Cancer Society in Atlanta found the overall risk of dying from cancer was 16% lower among people who took a daily aspirin pill for up to 11 years, with deaths from gastrointestinal cancers, such as oesophageal, stomach and colorectal cancers, falling by around 40%. Deaths from other cancers fell by 12% on average.
The findings, based on 100,139 men and women with no prior history of cancer, support previous claims that aspirin can protect against some forms of the disease, but suggest the effect is not as strong as those earlier studies found.
