Radiotherapy (also referred to as radiation therapy) has been used for more than a hundred years in cancer treatment. Nowadays cancer treatment is not imaginable without radiotherapy.
Whereas - until a few years ago radiation therapy has been associated with a quite high radiation exposure for a patient, today we can fight tumors with modern technologies, much more targeted and more successful. Radiotherapy is in some cases able to heal some types of cancer directly (curative radiotherapy), in other cases it is applied to support the primary therapy.
Radiotherapy can for example destroy possibly existing residual tumor cells after performance of chemotherapy. Such an “adjuvant” or complementary radiotherapy can protect the patient from a recurrence of the tumor (relapse).
