kiiritusraviga

Kiiritusravi, also known as radiation therapy, is a medical treatment that uses high-energy radiation to kill cancer cells and shrink tumors. It works by damaging the DNA of cancer cells, making it impossible for them to grow and divide. While it can also harm healthy cells, radiation therapy is carefully planned and delivered to minimize this damage.

There are two main types of radiation therapy: external beam radiation therapy and internal radiation therapy (brachytherapy). External beam radiation therapy uses a machine outside the body to deliver radiation to the affected area. Internal radiation therapy involves placing radioactive material directly inside the body, near the tumor.

Kiiritusravi can be used alone or in combination with other cancer treatments like surgery, chemotherapy, or immunotherapy. The specific type of radiation therapy, the dose, and the treatment schedule depend on the type and stage of cancer, as well as the patient's overall health. Side effects can vary depending on the area being treated and the dose of radiation, and may include fatigue, skin changes, and specific organ-related symptoms. Doctors work to manage these side effects to improve the patient's quality of life during treatment. Radiation therapy is a crucial tool in the fight against cancer, offering a non-invasive way to target and destroy malignant cells.
