ibuprofen for BC?

I heard that statistically women who take ibuprofen regularly get less BC. Somebody on the web is suggesting that BC patients apply it topically.

Does anyone have more info about this and if any one has gotten results? It certainly would be alot cheaper and I tolerate ibuprofen alot better than Celebrex. Thanks , Carol
