Cancers of the breast, endometrium and ovary can display endocrine sensitivity—and a proportion of such tumours regress when deprived of hormones (Hawkins & Miller, 1988). As a consequence, endocrine deprivation therapy is a major treatment modality, particularly in patients with breast cancer (Miller, 1990).

Given that endocrine factors also play a critical role in the aetiology of certain tumours (Preston-Martin, Pike, Ross et al. 1990), hormone manipulation might also prevent cancer. Initiatives attempting hormone-prevention of cancer have been given impetus by the availability of relatively non-toxic drugs such as luteinizing hormone-releasing hormone (LHRH) agonists and antioestrogens which block hormone action without the morbidity and irreversibility of surgical and radiological procedures. In this commentary we evaluate current thinking behind the use of hormone suppressant drugs as a method of prevention of cancer and conclude that such an approach is feasible but, in parallel with steroid contraception, there are important long-term consequences
