Säteilyterapiaa

Säteilyterapiaa, known in English 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. Radiation therapy works by damaging the DNA of cancer cells, preventing them from growing and dividing, and eventually leading to their death.

There are two main types of radiation therapy. External beam radiation therapy delivers radiation from a machine outside the body. This is the most common type and can be delivered in various ways, such as photons or protons. Internal radiation therapy, also known as brachytherapy, involves placing a radioactive source inside the body, close to the tumor.

The decision to use radiation therapy, and the specific type and dosage, depends on many factors, including the type of cancer, its stage, the patient's overall health, and whether other treatments are being used. Side effects can occur and vary depending on the area of the body being treated and the dose of radiation. Common side effects include fatigue, skin changes, and irritation in the treated area. These are usually temporary and can often be managed with supportive care. Radiation therapy is a complex treatment that requires careful planning and delivery by a specialized team of healthcare professionals.
