Chilton is a registered member of both Breast Surgeons of Australia and New Zealand and Australian and New Zealand Endocrine Surgeons professional societies.

Chilton graduated with Honours from the University of Melbourne Medical School in 2003 (MBBS Hons) and is a fellow of the Royal Australasian College of Surgeons (FRACS). He was one of the first graduates of the two-year BreastSurgANZ post-fellowship training program, the peak accrediting body for breast surgeons in Australia and New Zealand. His first fellowship year was spent training with the Breast and Endocrine Unit at The Queen Elizabeth Hospital in Adelaide, South Australia, during which time he obtained the Certificate of Clinician Performed Ultrasound (CCPU) with the Australian Society of Ultrasound Medicine. For his second fellowship year he trained in breast oncoplastic and reconstructive techniques at Royal Perth Hospital, Western Australia.

Upon his return to Melbourne in 2014 Chilton was invited by his mentors to commence as consultant surgeon at Monash Health, Victoria’s largest network of teaching hospitals, with dual appointments as both a breast surgeon at Moorabbin Hospital as well as a general surgeon in Casey Hospital where he trains and supervises the next generation of general surgeons.  Chilton was also made adjunct lecturer with the Monash University Department of Surgery and also a visiting surgeon with BreastScreen Victoria.  That same year he was awarded the John Collins Fellow Medal and Travel Grant by the ANZ Breast Cancer Trials Group.

Chilton offers his patients the latest techniques in breast cancer surgery. He introduced to Victoria the practice-changing use of radio-iodine seeds so that women no longer need traditional hookwires to locate tiny breast cancers for removal at surgery. Chilton also performs operations where patient radiotherapy is all performed at the time of their surgery under the one anaesthetic, saving patients weeks of radiation afterwards (intraoperative radiotherapy, IORT).
