säteilyhoitojen

Säteilyhoitojen, 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 part of cancer treatment, often used alone or in combination with other therapies like surgery or chemotherapy. The radiation works by damaging the DNA of cancer cells, preventing them from growing and dividing. While it targets cancer cells, radiation can also affect healthy cells in the treatment area. Modern techniques aim to minimize this collateral damage.

There are different types of radiation therapy. External beam radiation therapy is the most common, where a machine outside the body directs radiation at the tumor. Internal radiation therapy, also called brachytherapy, involves placing radioactive sources inside the body, close to the tumor. Systemic radiation therapy uses radioactive substances that travel through the bloodstream to reach cancer cells throughout the body. The specific type and dosage of radiation are determined by the type, size, and location of the cancer, as well as the patient's overall health.

Säteilyhoitojen is administered by a team of medical professionals, including radiation oncologists, radiation therapists, and medical physicists. Before treatment begins, a precise plan is created to ensure the radiation is delivered accurately. Side effects can vary depending on the area treated and the dose of radiation, but common ones include fatigue, skin irritation, and temporary hair loss. These side effects are usually manageable and often resolve after treatment is completed.
