Traditional external radiotherapy
In external radiotherapy, the radiation is applied through the healthy skin in the direction of the tumor location. Normally, the therapy takes about six weeks, during which the patient is required to come to the hospital or radiotherapy clinic for treatment on five days a week.
After radiotherapy planning and therapy simulation, the treatment is then performed using a device called a linear accelerator. In most radiotherapy centers, a "boost" treatment is also administered, in which the bed of the tumor is additionally exposed to radiation to ensure treatment efficacy.
33 treatment days over a period of 6-7 weeks, 5 times a week (Monday to Friday)
Some modern radiotherapy schedules may only take 3 weeks and these have recently been show to be as effective.
