Sisäistyshoito

Sisäistyshoito, also known as internal radiation therapy or brachytherapy, is a type of radiation therapy used to treat cancer. It involves placing radioactive sources directly inside the body, close to the tumor. This allows for a high dose of radiation to be delivered precisely to the cancerous cells while minimizing exposure to surrounding healthy tissues.

The radioactive sources can be temporary or permanent. Temporary sources are typically removed after a specific treatment duration, while permanent implants, often called seeds, are left in place and gradually lose their radioactivity over time. The method of delivery depends on the type and location of the cancer. It can be applied using applicators, catheters, or needles inserted into the tumor or a body cavity.

Sisäistyshoito is commonly used for cancers of the prostate, cervix, breast, skin, and head and neck. The procedure is usually performed under anesthesia, and patients may be hospitalized for a short period or treated as outpatients. Potential side effects are generally localized to the treatment area and can include pain, swelling, and discomfort, which often resolve as the radiation sources decay or are removed. The specific side effects depend on the area treated and the type of implant used. Its precise delivery makes it an effective and often preferred option for certain types of cancer.
