Radiotherapy is an important treatment in the patient care journey of many forms of cancer, its effectiveness is based on the use of radiation, generally X-rays, capable of hitting and destroying cancer cells and preserving mainly the healthy cells.
Generally, four out of ten people with cancer undergo chemotherapy treatment.
The radiation treatment is most frequently used for the cancers affecting the head-neck region, the breast and the urinary and genital tract.
Radiotherapy has different modalities and different fields of application; it can be external or internal radiotherapy, depending on the site where the radiation is administered, as well as having a curative role – radical radiotherapy – when the aim is to completely eliminate the localized tumor; palliative, if it is applied to relieve some symptoms caused by the tumor; pre-intra-post-operative if it is used to reduce the tumor mass before surgery, or if it is used during the tumor excision or, finally, if it is used following the removal of a tumor, to increase the probability to eliminate any residues. Another radiotherapy treatment is represented by total body radiotherapy, used in the event of multiple diseased cells within the body.
