What does radiation therapy mean?

Radiotherapy is an important means of using radiation to treat diseases such as tumors. Through advanced imaging technology and positioning equipment, radiotherapy can accurately determine the location and scope of tumors, ensure that radiation accurately irradiates the lesion site, and minimize the damage to surrounding normal tissues. Radiotherapy can be used as a primary or adjuvant treatment for tumors that are not suitable for surgery or are difficult to completely remove. Radiotherapy can achieve significant results in the treatment of a variety of tumors, effectively alleviating symptoms, prolonging survival time and improving quality of life. Although radiotherapy may cause some side effects, such as radiation dermatitis, oral mucositis, etc., through reasonable treatment planning and careful care, side effects can be controlled within an acceptable range, and with the end of treatment, many side effects will gradually reduce or disappear. It is often used in combination with surgery, chemotherapy and other treatment methods to play a synergistic role in improving the cure rate of tumors. For example, preoperative radiotherapy can reduce tumor size and facilitate surgery; postoperative radiotherapy can eliminate residual tumor cells and reduce the risk of recurrence. Radiotherapy plays an important role in tumor treatment, bringing hope for survival and better quality of life for patients. Its continuous development and perfection also provides strong support for overcoming diseases such as tumors.
