Add-Aspirin is a large randomised clinical trial, which is taking place in the UK, Republic of Ireland and India. It will recruit 11,000 participants to help find out whether regular aspirin use after treatment for an early stage cancer can prevent the cancer from coming back and preventing deaths.

A clinical trial looking at use of daily aspirin in healthy people aged 70 or over, has suggested that there is no overall benefit, when considering risk of death, dementia or physical disability.
The trial involved 19,000 healthy individuals aged 70 years or older, who were asked to take either a low-dose (100mg) aspirin tablet or a placebo (dummy) tablet daily for 5 years. The numbers of people who died or were diagnosed with dementia or a physical disability were similar in the two groups. Aspirin also did not appear to reduce the number of people having a heart attack or stroke as has been seen in studies of other groups of people (such as those with a higher than average risk of these events).
