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
Dr Kuhan is very responsive and he replies to every single query of Treatment We are seeking télé consultation From him and we are satisfied with Services team Lucio is also brilliant .
For patients with aggressive cancers, the battle against the disease is fraught with challenges. The suffering caused by the illness and the toxic side effects of treatment severely impact patients’ quality of life; throughout this process, patients frequently require guidance or advice from their doctors. However, the healthcare services provided by Canada’s public healthcare system are fraught with shortcomings: patients cannot contact their attending doctors directly but must be put through via a nurse, which can result in delays of several hours or even days in the management of their condition. In this regard, Dr Hariharan Kuhan of Lucio Health has always responded promptly to my emails, providing timely medical guidance and advice on how to proceed – often at the expense of his own free time. As cancer patients, throughout the long course of treatment, they must not only endure the physical pain of the illness but also cope with psychological and emotional challenges; their consultant is their strongest source of support. By comparison, the Canadian public healthcare system falls short. My attending physician only holds a scheduled consultation with me every two to three weeks, and even when we meet, there is not enough time to discuss my condition in detail. Dr Hariharan Kuhan of Lucio Health always answers my questions promptly, and his responses are warm, patient, thorough and comprehensive. He has given me the courage to overcome my illness! For cancer patients, the treatment plan is undoubtedly of the utmost importance. The treatment plan devised for me by Dr...
Read moreHaving a stage 4 cancer diagnosis I was lucky enough to find Dr Hari. I have never looked back, Tumours have now shrunk I still have 3 monthly consultations via zoom calls were Dr Hari checkes over all test results,I can honestly say I could not have done it without Dr Hari he is a dose of medicine himself, he has been there for both my wife and I leading us in all aspects of cancer care, we both feel upbeat and positive after each zoom consultation and confident for the future with him by our side
Hari is very knowledgeable, informative, patient, kind and caring, with an innate capacity to listen to and to hear what is being said. He has a grounded, well-balanced approach to the most challenging and complex medical situations, which inspires genuine confidence in his advice and approach.
Working with Dr Hari, integrative oncologist, has been a hugely positive and supportive part of my treatment. He is friendly, approachable and always willing to listen, which has made a real difference to me. He has been particularly helpful in managing my anxiety around blood results and scans. He responds quickly when I have concerns and is always reassuring when that is what I need. At the same time, he is happy to offer knowledge, advice and another perspective alongside my current treatment. I feel that Dr Hari takes the time to understand not only my treatment needs but also how I am feeling emotionally. Having someone who listens, responds promptly and provides reassurance and guidance has helped me feel much more supported and less anxious throughout my treatment.
Dr Hari is informative and very encouraging.
Dr Hari Kuhan is far and away the best doctor we have found in the 3 years since I was diagnosed with metastatic prostate cancer. He is immensely knowledgeable and caring. He is the only doctor we have met who has provided us with written advice after a consultation. His detailed written treatment plans provide a clear path forward in this otherwise overwhelming and confusing situation. Unlike other Oncologists, Dr Hari seems to welcome our questions and always replies promptly. I thoroughly recommend Dr Hari Kuhan to any prospective patient. We only wish we had found him sooner.
Dr Hari is always incredibly friendly, supportive and compassionate during every consultation. He is very open to answering any questions we have and provides clear, informative guidance on areas that can sometimes be difficult to get information about through our NHS oncology appointments. Most importantly, he is empathetic and takes the time to listen carefully to anything that is worrying my mum, making her feel heard and understood. She consistently comes away from each consultation feeling much more reassured, at ease and calmer than she did beforehand. We really value the time, care and reassurance he provides.
Dr Kuhan has been excellent throughout the time i have been with Lucio Health. I cannot speak of him highly enough. Dr Kuhan has guided me through the treatment adjusting the dosages when required due to my condition. He is passionate and very knowledgeable, I feel completely safe with any discissions Dr Kuhan makes.
