radioterapibehandling

Radioterapibehandling, often referred to as strålebehandling or strålbehandling, is a medical treatment that uses high-energy radiation to kill cancer cells and shrink tumors. It is a common and effective method used in the treatment of many types of cancer. The radiation works by damaging the DNA of cancer cells, preventing them from growing and dividing. While it is designed to target cancer cells, radiation can also affect healthy cells in the treated area. Modern radiotherapy techniques aim to minimize damage to surrounding healthy tissues.

There are two main types of radiotherapy: external beam radiation therapy and internal radiation therapy (brachytherapy). External beam radiation therapy involves using a machine outside the body to direct radiation toward the cancerous area. Brachytherapy involves placing radioactive sources inside the body, either temporarily or permanently, near the tumor. The specific type of radiotherapy used depends on the type, size, and location of the cancer, as well as the patient's overall health.

Radiotherapy can be used alone or in combination with other cancer treatments, such as surgery, chemotherapy, or immunotherapy. It may be used to cure cancer, control its growth, or relieve symptoms such as pain. Side effects of radiotherapy can vary depending on the area being treated and the dose of radiation, and may include fatigue, skin changes, and irritation in the treated area. These side effects are usually temporary and can be managed by the medical team.
