A Personalized, Compassionate Approach to Cancer Care
I offer my patients a personalized, compassionate approach rooted in my extensive experience as an oncologist. Moreover, each treatment plan is tailored to the individual, ensuring the most effective therapies are used while considering every patient’s unique circumstances.
Beyond this, my holistic philosophy emphasizes not only medical care but also emotional and psychological support, including guidance for family members throughout the cancer journey.
Importantly, my patients benefit from a dedicated multidisciplinary team that understands the importance of comprehensive, family-centered cancer care. Together, we ensure that every aspect of treatment is delivered with expertise, empathy, and attention to detail.

CONDITIONS I TREAT
I specialise in diagnosing and treating complex thoracic cancers with evidence-based therapies and compassionate care.
Lung Cancer (NSCLC & SCLC)
Lung cancer is one of the most common cancers and comes in two main forms: non-small cell and small cell. The difference is mainly how quickly they grow and spread. However, early diagnosis makes a big difference. Today, treatments may include chemotherapy, immunotherapy, or targeted drugs, often combined to achieve better results. As a result, patients can now benefit from more effective and personalised care plans.
Mesothelioma
Mesothelioma is a rare cancer that develops in the thin layer of tissue surrounding the lungs and other organs. Typically, it is linked to past exposure to asbestos. Although it can be aggressive, new treatments such as immunotherapy are helping to improve both survival and quality of life. Consequently, patients and their families now have more hope and support than ever before.
Thymic Tumours
Thymic tumours begin in the thymus, a small gland located in the upper chest. While some types grow slowly, others can be more aggressive. Nevertheless, even though these cancers are rare, ongoing advances in treatment – including targeted therapies and immunotherapy – are opening new possibilities for patients. As a result, long-term outcomes are steadily improving.
