Rayos Contra Cancer (RCC) is a non-profit telehealth organisation. We improve access to cost-efficient cancer treatments for patients in low-resource settings and connect clinics in low middle income countries with U.S.-based centralized radiation oncology support to promote medical training, research and infrastructure development. We collaborate with U.S.-based medical physicists, radiation oncologists, cancer centres, non-profit groups and international cancer organisations. We provide strategic and operational guidance to LMIC clinics and provide hand-holding to execute end-to-end solutions.
