Welcome to Add-Aspirin

This website is designed to provide information about the Add-Aspirin Trial, both for people taking part in the trial (participants) and collaborators. Please use the menus at the top of the screen to find out more about the trial.

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.
