Our Mission

Rayos Contra Cancer (RCC) is a non-profit with the mission to improve outcomes for cancer patients in limited-resource settings around the world. RCC focuses on radiotherapy, a critical component of cancer care that is recommended in over 50% of cancer cases. For radiotherapy to be as helpful as it can be for patients, it must be administered by well-trained clinicians, including radiation oncologists, medical physicists, dosimetrists, and radiation therapists.

RCC works with existing radiotherapy clinics in limited-resource settings to empower local clinicians. RCC creates and organizes free, easy-to-access training opportunities that provide clinicians with the concepts and skills they need to ensure optimal patient outcomes. Our training programs are made possible through the support of expert volunteers, who generously share expertise from their many years of practicing radiotherapy.


Across the globe, over 70% of cancer cases occur in low- and middle- income countries. This number is expected to grow as the prevalence of cancer increases rapidly in the developing world. Safe, timely, and effective cancer treatment is a challenge today, and will continue to challenge us tomorrow. Today, we need to work together to share our problems, our insights, and our solutions.

Availability of Radiotherapy Machines

The availability of radiotherapy equipment is one snapshot of the disparity in global radiotherapy access. As seen in these maps, there is a clear need for greater radiotherapy access in Latin America, Africa, Asia, and Eastern Europe.

In recent years, many new radiotherapy clinics have been established in these regions. RCC works with clinics who have recently acquired new equipment, to share best practices from clinicians who have experience working with that treatment modality. RCC is committed to working with clinics to improve patient outcomes, recognizing the economic, sociopolitical, and geographical factors that all play a role in cancer care.

These maps reflect the global availability of linear accelerators, Cobalt-60 teletherapy machines, and HDR-brachytherapy machines. Data was obtained using the Directory of Radiotherapy Centers (DIRAC) database compiled by the International Atomic Energy Agency (IAEA). Population values were obtained from the United Nations Population Division estimates.
