sädehoidolle

Sädehoito, also known 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 component of cancer treatment, often used in conjunction with other therapies like surgery and chemotherapy. The radiation works by damaging the DNA of cancer cells, preventing them from growing and dividing. While it targets cancer cells, it can also affect healthy cells in the vicinity, which is why side effects can occur.

There are two main types of radiation therapy: external beam radiation therapy and internal radiation therapy (brachytherapy). External beam radiation therapy is the most common form, where a machine outside the body directs radiation at the tumor. Brachytherapy involves placing radioactive sources directly inside or near the tumor. The specific type of radiation therapy used depends on the type, size, and location of the cancer, as well as the patient's overall health.

Sädehoito is prescribed by a radiation oncologist, a physician specializing in the use of radiation for cancer treatment. Treatment plans are highly individualized and are designed to deliver the maximum possible dose of radiation to the tumor while minimizing damage to surrounding healthy tissues. This is often achieved through precise targeting and careful planning of each treatment session. The duration and frequency of radiation therapy vary widely, from a few days to several weeks.
