      Radiotherapy – or radiation therapy – incudes a large number of techniques that use high energy (X rays) or ionising radiation to destroy or control cancerous cells.

      It is the use of radiation to kill a tumor. Radiation damages cells by causing damage to their DNA. It does not work specifically for cancer cells, so healthy tissue will also be affected by the radiation. To overcome that problem, several weak beams coming from different angles can be combined, which intersect at the location of the tumor. That way, the tissue that each beam passes through gets only a low dose of radiation, and thus less damage, and only at the tumor, where all beams intersect, is the radiation high enough to be harmful.

      Is that like radiation therapy for cancer? Sorry, I don’t know much about it.

      Radiotherapy is the use of radiation to treat things such as cancer by focussing it on cancerous cells and trying to destroy them
