Welcome to ONC-Hyperthermia, the only practice in sub-Saharan Africa offering modulated electro-hyperthermia (oncothermia) in a hospital setting.
This advanced and specialised treatment selectively heats cancer cells to make them more responsive to chemotherapy and radiotherapy. This technique is also highly targeted, so there is minimal damage to healthy tissues, and it is a comfortable and safe procedure for patients.
Our unique approach to hyperthermia treatment in oncology is the dynamic synergy of the expertise of oncologists combined with the innovative potential of the thermal and non-thermal effects of oncothermia – delivering a treatment at the forefront of modern medical advancements.
At ONC-Hyperthermia, we provide a holistic and comprehensive approach that integrates cutting-edge technologies and compassionate care, empowering our patients on their journey towards healing and recovery.
Hyperthermia is often indicated when you have a recurrence in a previously irradiated region, when you have exhausted all other treatment options, or if you have a tumour that is known to be particularly stubborn in responding to treatment.
Hyperthermia has been investigated for the management of various types of tumours, including tumours of the gastrointestinal tract, urinary tract, liver, lung, head and neck, brain, cervix, and prostate, as well as on melanomas, and sarcomas. If you have one of these cancers, you may benefit from hyperthermia treatments. This is however not an exhaustive list and there are other types of cancers which can be treated.

Dr Carrie Minnaar first studied hyperthermia in Germany in 2009 and completed her PhD on hyperthermia in oncology at Wits in 2019 and now practices oncologic hyperthermia at the Wits Donald Gordon Medical Centre.
Dr Carrie Minnaar is currently researching the use of modulated electro-hyperthermia for the management of brain tumours in adults and children and also also devoting much of her time in campaigning for the acceptance and inclusion of hyperthermia in oncology practices in South Africa.
