Patient: I have been amenorrheic for 5 years, no lactation, and this year I noticed a reduction in breast size with hair growth around it; after gamma treatment in August 2005, the microadenoma shrank from 1.2cm to 0.9cm (this is the result of the examination in February this year), and the PRL value is 120 (the result of the examination in June this year). Is it possible for me to undergo surgery again? Doctor: Surgery is possible, but gamma knife is not recommended. Also, I don’t know if you have been treated with bromocriptine medication, but if it is effective, medication is also possible.
