Radiotherapy / Radiation Therapy

Radiotherapy uses x-rays to destroy cancer cells. In most cases, the area where the cancer is in the body is marked with a pen on the skin and then a radiation machine is directed at that area. This is called external radiotherapy. It is also possible to have internal radiotherapy and then a small piece of radioactive material is placed inside the body near where the cancerous cells are located.

Radiation therapy can be given as a one off treatment in one visit but it is often given daily (except at weekends) over several weeks and then we call it a ‘course of treatment’. Each session of radiation can be given for a few seconds or for several minutes. The strength of the x-rays that are used and the amount of treatment sessions will vary amongst people.

It doesn’t hurt but people have to lie completely still during the treatment session so that can be a bit uncomfortable if it’s an awkward position. Also, the skin area where the radiation goes through might get red and a bit sore but the radiographer and specialists nurses will help with advice on how to minimize side effects like that and potential other side effects from the treatment.
