[2025-09-29T18:19:55.817036] [PI reasoning] **Defining brachytherapy**

I’m focusing on answering what brachytherapy is. It involves placing a radioactive source inside or near the treatment area, like putting implants within tissues. So, the correct answer would be C, which is irradiation by implants within tissues. I want to keep my reasoning concise and support it with reliable evidence, maybe from sources like NCCN or standard textbooks. I think a quick search for evidence would be helpful!
