Radiation oncology is a medical specialty that involves treating cancer with radiation. Doctors who specialize in treating cancer with radiation (radiation oncologists) use radiation therapy to treat a wide variety of cancers.

Radiation therapy uses carefully targeted and regulated doses of high-energy radiation to kill cancer cells. Radiation causes some cancer cells to die immediately after treatment, but most die because the radiation damages the chromosomes and DNA so that the cells can no longer divide and the tumor can't grow.

Radiation oncologists at Mayo Clinic in Florida treat malignant diseases and work closely with medical oncologists, surgeons and other doctors to coordinate the best care for you.
