Advanced radiation treatment in San Diego

Nearly two of every three people with cancer require radiation therapy as part of their care. Scripps MD Anderson Cancer Center specialists use some of the most advanced radiation therapy technologies available to treat cancer, either alone or with other treatments such as surgery and chemotherapy.  


Our highly skilled teams of trained medical and scientific professionals specialize in radiation therapy, including radiation oncologists, physicists, dosimetrists and radiation therapists. Using the latest technology, our teams care for patients with powerful, precise radiation treatment.


The Scripps MD Anderson radiation therapy centers have been awarded accreditation by the American Society for Radiation Oncology (ASTRO) through APEx — the Accreditation Program for Excellence®. The APEx accreditation program validates a radiation oncology facility’s excellence in delivering safe, high-quality patient care. Accreditation through APEx is a voluntary and rigorous multi-step process including equipment, modalities, techniques, and oncology information and treatment planning systems used at each center. The accreditation demonstrates our continued focus on safety and quality and our commitment to patient-centered care.

Types of radiation therapy

There are several types of radiation therapy. The most appropriate type for each patient depends on their cancer type, how far it may have spread, their medical profile, overall health and more.


Many patients find it helpful to understand the different types of radiation therapy and how they work. Scripps MD Anderson offers three main types of radiation therapy for cancer:


  • External beam radiation to treat cancer from outside of the body using radiation beams produced by a machine
  • Internal beam radiation to treat cancer from within the body using radioactive substances implanted in or near the tumor
  • Systemic radiation therapy, which uses radioactive substances that travel throughout the body in the blood to attack cancer cells
