Radiation Therapy (Asbestos)

Treatment with high-energy rays to destroy or shrink cancer cells.

Radiation Therapy (Bladder Cancer)

The use of high-energy waves similar to x-rays to treat a cancer. Radiation therapy is usually used to treat a local area of disease and often is given in combination with chemotherapy.

Radiation Therapy (Breast Cancer)

The use of high-energy radiation from x-rays, gamma rays, neutrons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy, implant radiation, or brachytherapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that circulates throughout the body. Also called radiotherapy.

Radiation Therapy (Cancer)

(ray-dee-AY-shun THER-ah-pee) The use of high-energy radiation from x-rays, gamma rays, neutrons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy, implant radiation, or brachytherapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that circulates throughout the body. Also called radiotherapy.

Radiation Therapy (Clinical Trials)

The use of high-energy radiation from x-rays, gamma rays, neutrons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or from materials called radioisotopes. Radioisotopes produce radiation and can be placed in or near the tumor or in the area near cancer cells. This type of radiation treatment is called internal radiation therapy, implant radiation, interstitial radiation, or brachytherapy. Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that circulates throughout the body. Also called radiotherapy, irradiation, and x-ray therapy.

Radiation Therapy (Colon Cancer)

The use of powerful beams of energy known as ionizing radiation to destroy cancer cells, thereby shrinking or eliminating a tumor.

Radiation Therapy (Colorectal and Pelvic Floor Diso)

Treatment with high-energy rays (such as x-rays) to kill cancer cells. The radiation may come from outside the body (external radiation) or from radioactive materials placed directly in the tumor (implant radiation). Also called radiotherapy.

Radiation Therapy (Ear Surgery)

The use of radiation energy to interfere with tumor growth.

Radiation Therapy (Erectile Dysfunction)

X-ray treatment that damages or kills cancer cells.

Radiation Therapy (Health)

Treatment that utilizes external-beam radiation

Radiation Therapy (Hormone Replacement Therapy)

The use of high-powered x-rays to destroy cancer cells.

Radiation Therapy (Legal, Mesothelioma)

Treatment with radiation to destroy cancer cells. This type of treatment may be used to reduce the size of a cancer before surgery, to destroy any remaining cancer cells after surgery, or, in some cases, as the main treatment.

Radiation Therapy (Lymphoma)

Radiation therapy (also called radiotherapy) uses high-energy radiation from x-rays and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation therapy) or from materials that produce radiation (radioisotopes) that are placed inside the body in the area where the cancer cells are found (internal radiation therapy, implant radiation, or brachytherapy). Systemic radiation therapy involves giving a radioactive substance, e.g., a radiolabeled monoclonal antibody, that circulates throughout the entire body.

Radiation Therapy (Medical)

Treatment of a disease, such as cancer, using forms of radioactivity that damage or destroy abnormal cells

Radiation Therapy (Nutrition)

A type of treatment, most often used for cancer, that involves the use of ionizing radiation, including Roentgen rays, radium, or other radioactive substances to destroy specific areas of tissue. It is also called radiotheraphy.

Radiation Therapy (Oncology)

Radiation therapy, or radiotherapy, involves the delivery of high-energy x-rays, electron beams or radioactive isotopes (chemicals) over time to destroy cancer cells, to prevent the spread of cancer, or to shrink a tumor. Radiation therapy may be external or internal. External radiation therapy directs a beam at the tumor site. Internal radiation therapy may be administered by intravenous (into the vein) injection, intracavity implantation (e.g. in the uterus), or interstitial (into the tumor) insertion. Radiation works by damaging the DNA of malignant cells. Normal cells recover more fully from radiation therapy than do cancer cells. General side effects of radiation therapy may include fatigue, skin changes, and loss of appetite. Other site-specific side effects can occur and should be discussed with a physician.

Radiation Therapy (Pituitary)

The use of radiation energy to interfere with tumor growth. See irradiation.

Radiation Therapy (Prostate Cancer)

Treatment with high-energy rays from x-rays or other sources to damage cancer cells. The radiation may come from a machine (external radiation therapy) or from radioactive materials placed inside the body as close as possible to the cancer (internal radiation therapy or radioactive seed implant).

Radiation Therapy (Skin Cancer)

The use of x-rays, ultraviolet rays and/or any electromagnetic radiation, possibly even light, in order to treat skin cancer or skin disease. An example of radiation therapy is the use of x-radiation to treat acne in children decades ago, which now causes those same patients to grow skin cancers wildly and aggressively. Another example would be the use of x-radiation or other radiation to destroy a skin cancer, such as a cancer growing into the ear of an 85-year-old patient, in whom major reconstructive surgery could cause a problem with bleeding, stress or heart disease.
