Dr. Harsh Dua

Dr. Harsh Dua is a senior medical oncologist at Indraprastha Apollo Hospital in New Delhi with over 35 years of clinical experience treating a comprehensive range of solid malignancies including gastrointestinal, lung and breast cancers. He is one of Apollo Delhi's most experienced oncologists and a recognised authority in systemic cancer therapy, biologic agents and precision oncology. Dr. Dua completed his MBBS followed by specialised training in Medical Oncology, building a clinical foundation in chemotherapy, targeted therapy and the management of complex solid tumours across all disease stages. Over three decades he has continuously updated his practice to incorporate new evidence and novel therapeutics as they emerged in this rapidly evolving specialty. His principal clinical focus is gastrointestinal oncology – colorectal cancer, gastric cancer, oesophageal cancer, pancreatic cancer and hepatocellular carcinoma – where he has extensive experience with both curative-intent and palliative systemic therapy protocols. In lung cancer, Dr. Dua has been at the forefront of adopting EGFR inhibitors, ALK inhibitors and PD-1/PD-L1 immunotherapy in molecularly selected patients, delivering outcomes that significantly exceed historical benchmarks for advanced-stage disease. Dr. Dua's approach to oncology is underpinned by molecular profiling and biomarker testing. He ensures every patient with solid malignancy has appropriate genomic testing – NGS panel, PD-L1 IHC, MSI status, KRAS, EGFR, ALK as relevant – before treatment decisions are finalised. This commitment to personalised oncology ensures patients receive therapy most likely to benefit their individual tumour biology rather than generic protocol-based chemotherapy. With extensive experience in biologic agents, targeted small molecules and checkpoint immunotherapy, Dr. Dua manages both first-line and heavily pre-treated patients who have progressed through multiple therapy lines and seek novel or clinical trial options. He participates in multiple international and national clinical trials through Apollo Delhi's oncology programme, giving patients access to investigational therapies not available outside trial settings. A compassionate communicator, Dr. Dua is particularly valued for his skill in explaining complex treatment options clearly and sensitively to patients and families navigating difficult diagnoses. His palliative oncology expertise ensures symptom control and quality of life receive equal attention alongside anti-cancer treatment. Recognised with the Apollo Gold Award in Oncology and Outlook Health Best Medical Oncologist Award, Dr. Harsh Dua at Indraprastha Apollo Hospital delivers three decades of systemic oncology expertise to patients in Delhi NCR and internationally, with a personalised evidence-based approach combining scientific rigour with genuine human compassion.
