radiotherapy -

Radiotherapy or also called radiation therapy is a therapy using radiation that comes from radioactive energy. Quite a lot of cancer patients who go to the hospital receive radiation therapy. Sometimes the received radiation is a single therapy, sometimes combined with chemotherapy and/or surgery. Not infrequently also a cancer patient receives more than one type of radiation.

Radiation therapy, also called radiotherapy, irradiation, x-ray therapy, or the popular term "dibestral" aims to destroy cancerous tissue. At least to reduce the size or eliminate the symptoms and disorders that accompany it. Sometimes even used for prevention (prophylactic). Radiation destroys the cell's genetic material so that the cell can not divide and grow again.

Not only cancer cells are destroyed by radiation. Normal cells, too. Therefore in radiation therapy doctors always try to destroy cancer cells as much as possible, while avoiding possible healthy cells in the vicinity. But even if exposed, most normal and healthy cells are able to recover from the effects of radiation.

Radiation can be used to treat virtually all types of solid tumours including brain, breast, cervical, throat, lung, pancreatic, prostate, skin, etc, even leukaemia and lymphoma. How and the dose depends on many things, including the type of cancer, its location, whether the surrounding tissue prone to damage, general health and medical history of patients, whether patients undergo other treatment, and so forth.

Radiation therapy of many kinds. Broadly divided into external radiation (using machines outside the body), internal radiation (implant/implant), as well as systemic radiation that follows the blood flow throughout the body. The most widely used is external radiation. Partly a mixture of external and internal or systemic radiation. Both types of radiation are sometimes given alternately, sometimes simultaneously.
