Sädehoito

Sädehoito is a form of cancer treatment that utilizes high-energy particles or radiation to kill cancer cells. The term "sädehoito" is derived from the Finnish language, translating to "radiation therapy" in English. This treatment method is often used in conjunction with other cancer therapies, such as surgery or chemotherapy, to treat various types of cancer.

Sädehoito can be administered through several methods, including external beam radiation therapy (EBRT), internal radiation therapy (IRT), and brachytherapy. EBRT involves directing a beam of radiation from an external source onto the tumor, while IRT uses radioactive seeds or rods inserted directly into the tumor. Brachytherapy involves placing the radioactive source inside or near the tumor.

The goal of sädehoito is to target cancer cells while minimizing damage to surrounding healthy tissues. This is achieved through precise targeting of the tumor, using advanced technologies such as conformal radiation therapy and intensity-modulated radiation therapy (IMRT). Sädehoito has been shown to be effective in treating a wide range of cancers, including breast, prostate, lung, and brain cancers.

Side effects of sädehoito can include fatigue, skin changes, and hair loss. In some cases, patients may experience more severe side effects, such as bowel or bladder problems. To minimize these risks, healthcare providers closely monitor patients undergoing sädehoito and adjust treatment plans as needed.

Research and development in sädehoito continue to advance, with ongoing efforts to improve treatment efficiency and accuracy. New technologies and delivery systems, such as stereotactic body radiation therapy (SBRT) and proton therapy, are being explored to enhance the efficacy and safety of sädehoito.
