Fewer second cancers with proton radiotherapy: research
Findings from this large epidemiological study should be heeded, Harvard radiation oncologists say
Patients with cancer are less likely to develop another primary cancer if their radiotherapy is carried out with protons rather than photons, a large US study shows.
But the absolute level of second primary cancers diagnoses is low, even with photon radiotherapy, at 1.55 per 100 patient-years, researchers say.
