The LHRH analogue Zoladex was used to treat 21 premenopausal women with severe recurrent or refractory breast pain. Severity and pattern of mastalgia, whether cyclical or non-cyclical, was assessed using self-administered record cards. Symptom relief was achieved in 17 (81%) of the patients. This study showed Zoladex to be an effective short-term treatment for refractory and recurrent mastalgia.
