What is the purpose of internal radiation therapy?

The purpose of internal radiation therapy, also known as brachytherapy, is to deliver radiation directly to the tumor. This technique involves placing a radioactive source inside or very close to the tumor itself, allowing for a concentrated dose of radiation to target cancerous cells while minimizing exposure to surrounding healthy tissues. By using this method, healthcare providers can maximize the treatment's effectiveness against the tumor and reduce the side effects that might occur if radiation were delivered externally.

This approach is particularly beneficial for certain types of cancers, where direct application of radiation can be more effective than external methods. It allows for a more localized treatment, which can support better outcomes and potentially lower the risk of damage to adjacent organs. The design of internal radiation therapy also often facilitates shorter treatment times, as higher doses can be administered over a shorter period compared to external radiation therapies.
