About Dr. Hariharan Kuhan

Dr Hariharan Kuhan is the Co-Founder and Medical Director of Lucio Health, where he leads the development of personalised, data-driven approaches to cancer and metabolic health. His clinical background spans mainstream oncology, early-phase trials, and academic research, with a strong focus on integrating metabolic medicine into modern cancer care.

Dr Kuhan studied medicine at Imperial College London, graduating with a BSc in Surgery and Anaesthesia. He completed his foundation and core medical training at major central London teaching hospitals before specialising in medical oncology at recognised UK centres of excellence.

During his research fellowship at Barts Cancer Institute, he explored metabolic pathways in cancer stem cells and circulating tumour cells, contributing to translational research that progressed into phase I human trials. He later served as a clinical fellow within a Harley Street early-phase trials unit, where he acted as lead sub-investigator on multiple solid tumour studies.

Dr Kuhan continues to be actively involved in clinical research and drug development. His expertise encompasses oncology, metabolic targeting, repurposed therapeutics, and genomic profiling, giving him a distinctive ability to bridge cutting-edge science with practical, patient-centred care. He is particularly passionate about making innovative, evidence-based treatments more accessible and supporting patients through truly personalised medicine.

De Hari has supported me for many years, ( also before Lucio Health) with my stage 4 ( metastatic) BC. A consult as normal via Zoom, followed by detailed clinical notes via e-mail. Recent blood test results and anything submitted before where discussed. Dr Hari is thorough, listened to my concerns and questions. Afterwards I felt confident and / or reassured to go back to my NHS health provider. The necessary medication is sorted via a trusted pharmacy.

Dr Hari is that rare clinician you can only hope to encounter in the patient journey. All too often, in my experience, clinicians are not the best listeners. Dr Hari not only listens, he is attentive, responsive and of course has exceptional clinical capability. He consults in a way which not only advises and educates but makes his patient feel stronger and more capable of addressing their illness. You leave his consultations feeling genuinely

I have been consulting Dr. Hari at Lucio Health for advanced CRC and have always had a great experience. Dr. Hari is not only incredibly knowledgable, also very kind, reassuring and exerts superb levels of professionalism in the way he goes over all of the details of the protocol and answers every question thoroughly. As a patient I feel very well-cared for. Dr. Hari and Lucio Health indeed provide the very best that integrative oncology can offer. All the Lucio Health staff were very kind, welcoming and professional as well. Highly recommended.

Hari is always prepared and read the notes, clarified the results, chceked with me on zoom call my feelings, symptoms etc before making suggestions and seeking my response. In difficult times when NHS have clearly abandoned me he has stepped up and been my 'rock' alongside McMillan cancer. Without Hari I most probably woudnt be here or on a painful decline but instead and exercising in the gym, enjoying life with my 90 year old father and grandkids

Dr Hari provides an incredible combination of traditional and integrated oncology that I have not found anywhere else (in 5 years of active treatment.) More than that, his positive attitude and proactive nature is unmatchable, as far as I've seen. My liver surgeon once told me that he wasn't sure if miserable people go in to oncology, or if oncology makes people miserable. Dr Hari is the exception to that rule. Russ RB

I have been under this doctor’s care for almost a year following a recurrence of breast cancer. As I live abroad, all our consultations have taken place remotely. I feel extremely fortunate to have found him. His approach combines excellent medical expertise with a comprehensive understanding of integrative medicine. His advice is consistently thoughtful, insightful and invaluable, particularly regarding my treatment and nutrition. He is exceptionally well prepared for every consultation, having carefully reviewed my medical records and fully familiarised himself with my history. He has become a true compass throughout my treatment. I greatly value his wise judgement and regularly seek his opinion. I could not be happier with his care and guidance, and recommend him wholeheartedly.

I have been speaking with Dr Hari for over a year now. His advice has been invaluable, and he has helped bridge the gap between mainstream medical advice and the use of functional off- label medicine. He has helped me make better decisions about my treatments, whilst keeping myself healthy and balanced, and also enjoy my life. He has helped me remain calm in some challenging situations. I have an aggressive BRAF mutation but have managed to keep myself NED, and I don't doubt it is because of his help and advice for the last year. Thank you kindly for being part of my team I wouldn't hesitate to recommend having him onside to help navigate a cancer diagnosis and to add another layer to a standard treatment plan. x
