This book covers the practical aspects of radiotherapy (RT) in genitourinary (uro-genital) cancers, empowering radiation oncologists and students with the confidence to treat these less common malignancies. It explores radiotherapy doses, indications, and target volumes in depth and in evidence-based manner. It also explains the role of brachytherapy in these malignancies. With a strong focus on patient outcomes, the book addresses the side effects of radiotherapy (including their management), which are crucial for long-term survivors and emphasizes the importance of individualized care. It also offers brief insights into other treatment modalities including hormonal therapy, surgery, and chemotherapy. Tracing the evolution of radiotherapy, the book highlights how modern radiotherapy techniques now enable higher precision in delivering high radiation dose and reduced toxicity, overcoming historical limitations without compromising efficacy. Designed for both students and practicing oncologists, this resource simplifies complex concepts and helps practice radiation in urogenital cancers in an easier and evidence-based manner.
