The world’s largest free-standing proton therapy centre has opened in Virginia, US.

The Hampton University Proton Therapy Institute is expected to treat about 2,000 patients with breast, brain, lung, prostate, paediatric and ocular cancers every year.

Patients will be treated for five days a week, for a period of five to ten weeks.

Proton therapy is a precise form of cancer treatment, which targets and kills tumours with millimetre accuracy, reducing damage to surrounding tissue.
