Men with ‘high risk’ prostate cancer can safely receive high-dose radiotherapy to kill cancer cells that have spread into neighbouring lymph nodes, a new study reports.

Targeting or reducing the dose of radiotherapy for women with breast cancer after surgery can substantially reduce the side effects they experience, a large-scale clinical trial has shown.

Women who received radiotherapy for early-stage breast cancer in fewer, larger doses experienced similarly low rates of late-onset side-effects as those receiving conventional treatment, results from a 10-year study show.
