Medicament for preventing and/or treating a mammary carcinoma, containing a steroidal aromatase inhibitor

摘要

A method of prophylaxis and/or treatment of mastocarcinoma (i.e., mammary carcinoma) involves the topical application of a therapeutically or prophylactically effective amount of a steroidal aromatase inhibitor locally, and not systemically, to an area of a patient in need of treatment. This local application avoids the side effects associated with systemic use of steroidal aromatase inhibitors.
