Dr. Harold Nathan Tan

I am a Consultant Medical Oncologist at the Makati Medical Center and St. Luke's Medical Center - Global City. I am currently a Clinical Research Fellow in the Drug Development Unit of The Royal Marsden Hospital in London, United Kingdom. Our unit treats close to 300 patients a year on Phase I trials, making it one of the largest facilities of its kind in the world. I am well-versed in the management and care of patients with breast, lung, genitourinary (bladder, renal, prostate), and gastrointestinal (esophagus, stomach, pancreas, colorectal, and liver) cancers. I am a member of the American Society of Clinical Oncology, the European Society of Medical Oncology (ESMO), American Association for Clinical Research (AACR), Society for Immunotherapy of Cancer (SITC), and the Philippine Society of Medical Oncology. I have attended and presented at numerous national and international conferences. I can also handle various adult diseases such as hypertension, heart disease, lung disease (COPD), respiratory infections (COVID-19, pneumonia), diabetes mellitus, diarrheal diseases, liver diseases, and kidney diseases.
