Global Radiation Oncology at Dartmouth

Radiation oncology is an effective cancer treatment and is used in over half of all cancer cases. Yet, access to this lifesaving therapy is not universal. In many low- and middle-income countries, especially across sub-Saharan Africa, fewer than 1 in 10 people have access to radiation treatment. Dartmouth is working to change that.

To help close this global gap in cancer care, Dartmouth’s Department of Radiation Oncology and Applied Sciences has launched a Division of Global Radiation Oncology. 

Core principles

Our mission is to improve access to radiological health around the world through a focused approach built on five core principles:

Implementation science

We help build and improve radiation therapy programs where they are needed most.

  • Helped launch Malawi’s first radiotherapy program
  • Designed shielding plans for a new cancer center in Kenya

Clinical training

We provide hands-on training for doctors, physicists, and technologists.

  • Delivered courses in advanced treatment planning in Nigeria
  • Conducted in-person educational visits and long-term collaborations in Mongolia

Virtual education

We make high-quality medical physics education available to everyone, everywhere.

  • Monthly lecture series viewed by people in over 60 countries
  • Practical online workshops with hundreds of participants from around the globe
  • Full academic courses delivered virtually to medical professionals in Kenya, Tanzania, Guyana, and Türkiye

Community engagement

We connect the worlds of global health and radiological science.

  • Leadership roles within NGOs involved on increasing and improving access to care
  • Work closely with global international organizations like the IAEA and WHO

Understanding the determinants of global radiological health

We study why gaps in access exist and what can be done about them.

  • Explore how historical, political, and economic factors shape today’s radiology and cancer care landscapes
  • Highlight the ongoing impact of colonial legacies on health infrastructure

Together, we are working to bring quality cancer care to communities everywhere.
