I did a Pubmed search for spironolactone +breast cancer, and I couldn't find recent studies.
Here is a case report about a man who took spironolactone and got breast cancer and hemophilia. www.ncbi.nlm.nih.gov/pubmed/15...
In this 1990 paper of 15 men who got breast cancer, almost half of them had a history of taking a spironolactone-type medication. Of course, spironolactone was used more then. http://www.ncbi.nlm.nih.gov/pubmed/2197584
This old study of over 300 women found no association between spironolactone and breast cancer. http://www.ncbi.nlm.nih.gov/pubmed/7114041
There are 2 letters to Lancet about the possible association between breast cancer and spironolactone in the mid-1970s, but there is no abstract posted. http://www.ncbi.nlm.nih.gov/pubmed/49594
It doesn't sound like this is an area of current research, or at least there haven't been many recent studies I can find.
