Exposing tumors to ionizing radiation kills them faster than it kills nearby healthy tissue. If you can focus or otherwise concentrate the radiation on the tumor the effect is even stronger.
The reason for this effect is tumors generally grow much faster than healthy tissue, and ionizing radiation damages growing tissue much more significantly than tissue that is not actively growing. This damage should kill it.
It is sometimes called radiation therapy, radiation therapy, cobalt therapy, electron beam therapy, or irradiation
Interstitial radiation therapy places the sources of radiation directly into the tumor and surrounding tissue.
Radiation therapy is delivered via external radiation or via internal radiation therapy (the implantation/injection of radioactive substances).
Radiation Therapy is not transferred to clothing.
Radiation therapy is a local treatment
It is sometimes called radiation therapy, x-ray therapy radiation treatment, cobalt therapy, electron beam therapy, or irradiation
In external radiation therapy a beam of radiation is directed from outside the body at the cancer
It is sometimes called cobalt therapy, radiation therapy, x-ray therapy radiation treatment, radiotherapy, or irradiation
It is sometimes called radiotherapy, x-ray therapy radiation treatment, cobalt therapy, electron beam therapy, or irradiation
Prostate cancer responds well to radiation therapy
Radiation Therapy dose is measured in Gray (abbrev. Gy).
If you are interested in taking a couple courses on radiation therapy, then there are many different kinds of schools that offer different courses in radiation therapy.
