[0002] Radiotherapy for breast cancer is an important treatment for breast cancer patients. After surgical treatment, in order to further eliminate possible residual cancer cells and prevent recurrence and metastasis, doctors will use radiation to irradiate the breast and surrounding areas. The radiotherapy process is precisely positioned and uses high-tech equipment to ensure that the radiation reaches the tumor site accurately while protecting normal tissue to the maximum extent. During the treatment, patients may experience some side effects, such as skin redness, swelling, fatigue, etc., but these are temporary and can be relieved by medication or care. Radiotherapy for breast cancer plays an important role in improving patient survival rates and improving quality of life.
