Radiation therapy, or radiotherapy, is a type of cancer treatment that uses a special device to direct high-energy beams (such as X-rays or protons) at cancerous tumors with the aim of destroying cancer cells or stopping their growth.<br /><br />The device precisely directs these beams to the affected area without the need for incisions or surgery. It can be used alone or in conjunction with chemotherapy or surgery, depending on the patient's condition.<br />How does a radiotherapy device work?<br />1. Tumor localization:<br />Before treatment begins, the patient undergoes precise imaging (such as a CT scan or MRI) to accurately determine the size and location of the tumor.<br />2. Treatment planning:<br />A precise plan is developed to distribute the radiation so that it reaches only the tumor, sparing healthy tissue as much as possible.<br />3. Treatment sessions:<br />The patient lies on a table under the device. The device rotates around them, directing the radiation at the tumor from different angles. The session typically lasts only minutes, and the patient feels nothing during the treatment.<br />Importance of radiotherapy:<br />• Kills or stops the growth of cancer cells.<br />• It is used to shrink tumors before surgery or to destroy remaining cells after surgery.<br />• Helps relieve symptoms caused by cancer, such as pain or bleeding.<br />• A safe and effective alternative when surgery is not possible.
