What Is Radiation Therapy?
Radiation therapy or radiotherapy focusses on delivering the dose as precisely as possible and limited to the affected tumor part sparing the unaffected normal tissues. This helps minimize the adverse effects caused to the cancer patient and avoids damage to the normal cells. Imaging tests in radiotherapy help in a better determination of the exact shape and location of the tumor and define its boundaries. The patient is instructed by the radiology specialist based on the type of exam being performed on the patient.
