This study is looking at the long-term effects of radiation therapy (radiotherapy) and how cancer naturally progresses in people who have already received this treatment. It's an observational study, meaning researchers will collect information from your regular follow-up care. The goal is to understand more about the side effects that can happen over time after radiotherapy and the natural course of different cancers. You might be able to join if you're an adult who has had radiation therapy and your doctor at the National Cancer Institute (NCI) or Radiation Oncology Branch (ROB) thinks it's best for you to be followed in their clinic. The study is ongoing and aims to include 700 participants.
