About Us


Nosworthy Oncology @Wits Donald Gordon Medical Centre is a practice designed to create a space where experts in various fields of cancer therapy (Adult Chemotherapy, Children’s Chemotherapy and Radiation therapy) can work collaboratively for the improved cancer outcomes of their patients. We regularly have other specialists (e.g., Surgeons) at the practice to formulate the best cancer treatment plan. This is to get the best outcomes for every patient that comes to our practice.

“The journey through cancer treatment can sometimes be difficult, and I hope that our practice makes this experience a little more bearable. Although I had a good idea of general medical practice from a young age, with my dad being a GP for over 50 years, I was still unsure of the specialty I would pursue when I graduated from Wits Medical School in 2002. It was when I was an intern that I found out what great strides were being made in the treatment of cancers and wanted to be on the forefront to “curing cancer”.  I started as a registrar in the Clinical and Radiation Oncology department at Charlotte Maxeke Johannesburg Academic Hospital in 2005 immediately after my community service year and graduated with a Fellowship in Radiation Oncology (FCRadOnc(SA)) from the Colleges of Medicine of South Africa in 2008. I’ve subsequently spent three years as a consultant in the Clinical and Radiation Oncology department Charlotte Maxeke Johannesburg Academic Hospital. In that time, I participated in the treatment and clinical trials of many cancer types. In mid-2011, I went into private practice, and joined the DMO group, working from the Sandton Oncology and West Rand Oncology practice. I became a partner in the practice in 2013 but felt that the way in which medicine and especially oncology was being managed needed improvement. I left the DMO practice in December 2016 and wanted to look at the best general management practices in the world. The place to learn this would be at one of the world’s leading business schools, and I spent 2017 commuting between London and South Africa completing an MBA at London Business School. I chose the school as they are consistently rated as one of the best global business schools and MBA programs, and felt that if I were going to innovate in medicine and oncology, this would be the best place to develop some tools to do it. Upon returning from the UK, I joined Adam, Owen and Debbie Nosworthy in their practice at Wits Donald Gordon Medical Centre. Nosworthy Oncology was a wonderful model of a “family” practice, where everyone that walks through the door is family, and this was a great place to be to deliver personalised cancer care.

After taking you on a tour through my journey, I’ll end by saying what I started with. The journey can be difficult, but I hope that our practice can make it a little more tolerable. Please feel more than welcome to make a consult with us to discuss your cancer treatment options. Our practice is much more than treating cancer. It’s about treating you.

At your first consult, we will go through your scan and pathology results and discuss possible treatment options. We work in a multidisciplinary team, and we discuss treatments with our team of expert team of surgeons and medical oncologists (chemotherapy specialists), and of course you! Once we have decided on the best path forward, we can start down the road to better health.”


I consulted Dr Ramiah for a second opinion after my very well known surgeon who operated on me for my breast cancer referred me to another oncologist. I am so glad I did. He was a complete breath of fresh air after the terrible experience with the first oncologist that I consulted. He has impeccable bedside manner, and presents all the options of treatment.
When I was diagnosed with rectal cancer in 2012, I was devastated. The fear of the unknown and death were unbearable. Dr Ramiah made this journey so much easier. He explains the treatment so that anyone can understand, and is always available if you are having any issues. I had my chemoradiation, followed by surgery, and I’m glad to say I’m still cancer free. Thanks Dr Ramiah
Great guy. Superb physician. I went to lots of oncologists before being lucky enough to him. He was a real revelation compared to the rest of them
I can’t say enough good things about Dr Ramiah. He really made my cancer treatment much more manageable

Extremely knowledgeable. Very kind, and an excellent oncologist. He was really a breath of fresh air after the number of doctors I had seen sing being diagnosed with breast cancer
