How can radiation kill cancer cells and not cause more cancer to develop?


Michael Corradetti, MD, PhD, Radiation Oncology Resident at Penn Medicine, responds:

Radiation treatments kill cancer cells primarily via damage to their DNA. A variety of technologies have been developed to deliver radiation therapies that maximize the dose to the tumor while sparing normal tissue. Unfortunately, there is no technology that limits the dose exclusively to the tumor; as a result, any radiation therapy comes with a small (but real) risk of a secondary malignancy.
