Patient Care Philosophy

I treat patients and give them advice that I would give if they were one of my family members or friends. The cancer journey affects not only the patient but their family. With the very dynamic world of medicine particularly with oncology, I aim to offer the latest information and help the patient and their family decide on a plan tailored to best suit them. This includes access to clinical trials and expertise of a multidisciplinary team approach.
