säteilyhoidoksi

Säteilyhoidoksi is a Finnish term that translates to "radiotherapy" in English. It refers to a medical treatment that uses radiation, often high-energy X-rays or particles, to damage or destroy cancerous cells and shrink tumors. Radiotherapy can be used alone as a primary treatment, or in combination with other cancer treatments such as surgery or chemotherapy.

The goal of radiotherapy is to deliver a precise dose of radiation to the tumor while minimizing damage to surrounding healthy tissues. This is achieved through careful planning and advanced delivery techniques. Before treatment begins, a radiation oncologist will determine the type and amount of radiation needed, as well as the best way to administer it. This often involves imaging scans like CT or MRI to precisely locate the tumor.

There are two main types of radiotherapy: external beam radiation therapy, where radiation is delivered from a machine outside the body, and internal radiation therapy (brachytherapy), where a radioactive source is placed inside the body, near the tumor. The specific type and duration of radiotherapy depend on the type and stage of cancer, as well as the patient's overall health. Radiotherapy can be used to treat a wide range of cancers, including breast, prostate, lung, and brain cancers, and plays a crucial role in modern cancer care.
