Jayant S. Vaidya

Vaidya was born in Goa, India, to Sharad Vaidya, a cancer surgeon, and Nirmala Vaidya, who together ran the Vaidya Hospital in Panaji, Goa, India.[4]

Vaidya received his medical degree (MBBS) from Goa Medical College, Bombay University. He received his first research grant while in the medical school. He moved to Mumbai in 1989 for his surgical oncology residency training and fellowship at municipal hospitals in Mumbai and the Tata Memorial Cancer Hospital.[5]

He migrated to London in the 1990s. In London, he worked as a surgical registrar in several London hospitals and as a clinical lecturer and research fellow at the University College London Hospital. Subsequently, he was elected Fellow of the Royal College of Surgeons of Glasgow and completed his PhD from University College London (UCL), followed by board certification by the Surgical Royal Colleges of Great Britain and Ireland.

In early 2000s, Vaidya developed targeted intraoperative radiotherapy for breast cancer.[6] From 2004 to 2008, he was Senior Lecturer at the University of Dundee and the Department of Surgery & Molecular Oncology, Ninewells Hospital, where he led the targeted intraoperative radiotherapy program and related breast cancer research. In 2008, he joined as a chair in the Division of Surgery and Interventional Science, University College London.[7][8]

During his surgical residency training at Tata Memorial Hospital in Mumbai, Vaidya was concerned about patients who had to make several visits to the hospital for 6 weeks postoperative radiotherapy. Some patients opted for mastectomy rather than trying to save healthy tissue, as they could not afford radiotherapy.[4][12]

Vaidya developed the technique he called targeted-intraoperative radiotherapy (TARGIT) in 1998, along with fellow UCL clinical academics Jeffrey Tobias and Michael Baum and in collaboration with device manufacturers. The technique involves delivering single-dose radiotherapy from inside the body via a small ball-shaped device placed inside the breast immediately after lumpectomy while the patient is still under anaesthesia. The procedure lasts for 20 to 30 minutes. This may remove the need for additional hospital visits, thereby improving patient safety and well-being.[13]

The first patient was treated with TARGIT in July 1998 at the Middlesex Hospital in London.[12] By 2014, TARGIT has been adopted at nearly 250+ centres in over 35 countries,[6] including by the NHS.[14]

Vaidya has appeared in various interviews on international media channels and featured on international dailies in connection with his work on breast cancer treatment.[15][16][17][18]

His family comes from Keri, Ponda, Goa. The surname "Vaidya" is a Sanskrit word meaning "doctor" or "traditional physician." The family derives this name from practicing medicine for over 300 years. He is the great-grandnephew of Dada Vaidya, a famous 19th century doctor from Goa.[19]

Vaidya has a wife and two children.
