Mission & Focus Areas
ASTRO’s strategic-plan mission is to advance radiation oncology by promoting equitable, high-quality care for people with cancer; cultivating and educating a diverse workforce; fostering research and innovation; and leading policy development and advocacy. Its vision is to improve the lives of people with cancer through radiation therapy.
ASTRO funds research and training opportunities for early-career radiation oncology researchers. Its website’s research topics include big data and artificial intelligence, biomarkers and the cancer genome, and research with potential to advance radiation oncology. A 2025 seed-grant announcement described eligible research scope that included basic, translational, and clinical research; health services research; health education; radiation effects on normal tissues; and cancer pathogenesis.
The 2025 grants went to organizations whose own missions span cancer research and services. For example, the American Cancer Society describes its mission as improving the lives of people with cancer and their families through advocacy, research, and patient support. NRG Oncology Foundation says it conducts multi-institutional clinical and translational research to improve the lives of patients with cancer. Latinas Contra Cancer describes its work as supporting prevention, detection, treatment, and survivorship by addressing barriers to high-quality care facing the Latine community.
Grantmaking
In filing year 2025, ASTRO reported 10 grants totaling $696,000. Grant amounts ranged from $8,500 to $362,500, with a median of $37,500. All 10 itemized grants listed research grant awards as their purpose.
The largest 2025 grants were $362,500 to the American Cancer Society, $100,000 to Washington University, and $50,000 each to Sloan Kettering Institute for Cancer Research, the American Association of Physicists in Medicine, and The General Hospital Corporation. Other listed recipients included NRG Oncology Foundation and LUNGevity Foundation, each at $25,000; Carter’s Foundation and Latinas Contra Cancer, each at $12,500; and Tony La Russa’s Animal Rescue Foundation at $8,500.
ASTRO’s website lists an active joint ASTRO–Breast Cancer Research Foundation Emerging Investigator Award offering up to $100,000 in direct costs for one year to an early-career breast radiation oncology researcher from an underrepresented population. The eligibility description requires the principal investigator to be able to self-identify as a member of an underrepresented population specified in the NIH diversity notice; indirect costs are not allowed. The website also lists a medical student fellowship award for underrepresented populations, but describes its funding as a stipend, travel support, and mentorship for a training program.
A 2025 Residents/Fellows in Radiation Oncology Seed Grant announcement offered up to $50,000 for a one-year award, with no indirect costs. Its application deadline was February 7, 2025, so that was a past cycle.
