Dr Johann Riedemann – Radiation Oncologist – Cape Gate

Dr Johann Riedemann – Oncologist (Radiation Oncologist) – Cape Gate practices at the Cancercare Cape Gate Oncology Centre, where he directs precision radiotherapy and integrated molecular oncology services. He earned his MBChB from the University of Stellenbosch in 2012 and subsequently completed his Fellowship in Radiation Oncology (FC Rad Onc SA) in 2020. Moreover, he holds an MSc in Molecular Oncology and pursued a PhD/post-doctoral fellowship focused on tumour biology, blending bench research with bedside care .

During his early career, Dr Riedemann served as a clinical research fellow and registrar at Groote Schuur and Red Cross Children’s Hospitals, where he honed expertise in paediatric and adolescent brain tumours. Consequently, he brings over a decade of specialist experience to every treatment plan. Furthermore, he sits on regional guideline committees and mentors junior clinicians, ensuring that emerging radiotherapy techniques—such as Intensity-Modulated Radiotherapy (IMRT) and Stereotactic Radiosurgery (SRS)—are adopted locally. Thus, patients benefit from cutting-edge, evidence-driven care.
