Prof Ian Kunkler speaks to ecancer about the Scottish breast conservation trial which showed that radiotherapy does not improve the survival of patients with early breast cancer after 30 years.

He says that this is one of the longest and most up-to-date follow-ups of randomised controlled clinical trials of breast-conserving therapy and it provides important information for long-term survivors of breast cancer and their doctors.

The study found that there is no long-term improvement in overall survival for those women who undergo radiotherapy.
