During Treatment


Simulation means measuring the patient anatomy and obtaining his/her images in order to have the treatment staff apply radiation in a secure and correct way every day.

During the simulation; a radiotherapy technician will help you to lie on the device and to take the position required for the treatment. After the process is completed, marks are placed on an assistive device or on your skin in order to specify the treatment area. Graphies taken during the simulation and tomographies taken previously in order to direct you treatment plan and to plan the simulation are different from the other tomographies and films that are taken for the diagnosis and follow-up of your disease and they cannot be used for this purpose.  During the simulation, the region where the treatment will be applied for your disease should be completely undressed. Simulation room will be dark during the process and two technicians will stand ready with you. During the progress; if required, radiation oncologist also accompanies to the process. Simulation is generally performed for once before the treatment but your doctor may plan another simulation process afterwards. The whole process takes approximately 15-20 minutes.


All the sessions applied are painless like taking films or tomographies. Radiation is directed from the treatment device where you are lying to your tumor localization. One of the advantages of radiotherapy is that because it is applied as outpatient sessions, you don’t need to leave your job or normal life for a long time.

Treatment is applied five days a week on week days, and treatment is interrupted on Saturdays and Sundays in order to leave the tissues for cure themselves. Total treatment period varies between 2 and 8 weeks according to your disease and other concurrent treatments.

At the beginning of the treatment; you will be informed about the matters that you have to do before and after every session. Generally it is recommended to eat normally, have a shower, and continue your normal movements and sleeping order, i.e. not to debase your standard life style. Wearing comfortable and light clothes is important for not increasing the side effects of the skin.

Every session of your treatment is applied by the radiotherapy technician according to the plan prepared by your doctor. Every session generally continues for approximately 5-15 minutes.

If an assistive device is being used during your treatment, this is repeated in every session in order to provide the stableness of your position.
After your correct positioning is provided, technician foes to the control room in order to apply your treatment and to watch you from the monitor.  If you have any disturbance or problem, technician will receive your call and may terminate the treatment immediately.  

You may hear different noises from the device during your treatment but you don’t need to worry for such noises because the device is always under the control of the technician.  

Although your therapy is planned so as to preserve the normal tissues around the tumour, you may still encounter side effects which you will feel increasingly apparently during the course of the therapy. If such side effects increase and start to severely affect your life despite the medical treatments recommended by your physician, the therapy may be paused for a couple of days. This interval will be added at the end of your therapy and will not the response to the therapy.
Your radiation oncologist will observe your therapy and may make changes in your therapy dosage as a result. During your therapy, your physician may request and check your blood values or other examinations according to your complaints with certain intervals.

Post-therapy follow-up

After the completion of the therapy, you are examined by your physician and assessed in terms of side effects. Your epicrisis is provided and you are directed to the physician who will conduct your therapy and follow-up during the course of your life.
