The use of a number of precisely aimed beams of ionizing radiation, each coming from a different direction and meeting at a specific point, to deliver radiation treatment to that spot.
- Radiation therapy, targeted
A procedure that uses computers to create a 3-dimensional picture of the tumor in order to target the tumor as accurately as possible and give it the highest possible dose of radiation while sparing normal tissue as much as possible. It is also known as 3-D conformal (or conformational) radiation therapy. Conventional radiation therapy directs […]
- Radiation, ultraviolet
Invisible rays that are part of the energy that comes from the sun. Ultraviolet radiation can burn the skin and cause skin cancer. Ultraviolet radiation is made up of three types of rays — ultraviolet A, ultraviolet B, and ultraviolet C. Although ultraviolet C is the most dangerous type of ultraviolet light in terms of […]
- Radical dissection
Surgical removal of not only affected tissue, but also nearby tissue that may be covertly affected.
- Radical neck dissection
Often called a ‘radical neck,’ a surgical procedure that involves the removal of a tumor from the neck with an additional margin of seemingly normal tissue of at least 2 cm together with the removal of the lymph nodes from the neck.
- Radical prostatectomy
A surgery procedure that removes the entire prostate gland plus some surrounding tissue. During the procedure the pelvic lymph nodes may also be sampled for a biopsy. The goal is to remove the cancer entirely and prevent its spread to other parts of the body.
