radioterápiát

Radioterápia, also known as radiation therapy, is a medical treatment that uses high-energy radiation to kill cancer cells and shrink tumors. It is a common and effective form of cancer treatment, often used in conjunction with surgery or chemotherapy. The radiation works by damaging the DNA of cancer cells, preventing them from growing and dividing. While radiation can also affect healthy cells, medical professionals use careful planning and advanced technology to minimize damage to surrounding tissues.

There are two main types of radiotherapy: external beam radiation therapy and internal radiation therapy (brachytherapy). External beam radiation therapy delivers radiation from a machine outside the body to the cancerous area. Brachytherapy involves placing radioactive sources directly inside or near the tumor. The type of radiotherapy used depends on the type, location, and stage of the cancer.

Radiotherapy can be used to treat a wide variety of cancers, including breast cancer, prostate cancer, lung cancer, and head and neck cancers. It can be used as a primary treatment to cure cancer, to control cancer growth, to relieve symptoms caused by cancer, or to prevent cancer from returning. Side effects of radiotherapy can vary depending on the area of the body being treated and the dose of radiation, and may include fatigue, skin irritation, and hair loss in the treated area. These side effects are usually temporary and can be managed with supportive care.
