- Radiation therapy
The use of high-energy rays to damage cancer cells, stopping them from growing and dividing. Like surgery, radiation therapy is a local treatment that affects cancer cells only in the treated area. Radiation can come from a machine (external radiation) or from a small container of radioactive material implanted directly into or near a tumor […]
- Radiation therapy, 3-D
A procedure that uses computers to create a 3-dimensional picture of the tumor in order to target it as accurately as possible and give it the highest possible dose of radiation while sparing normal tissue as much as possible. Also known as targeted radiation therapy and as conformal or conformational radiation therapy. Conventional radiation therapy […]
