In 1975 the Canadian oncologist Dr Vera Peters released ground-breaking data to prove that breast-conserving surgery could at times be as effective as having a radical mastectomy. Her findings were received with lukewarm support and even open opposition from many of her colleagues in the male-dominated medical profession. Mike Lanchin hears from Dr Peters' daughter, Dr Jennifer Ingram, about her mother's tenacious attempt to improve the well-being of breast-cancer sufferers.Photo:Dr Vera Peters (courtesy of the family)
