I have a cyst under my right nipple. I have noticed changes to that areola for several years. The size changes, in other words, both nipples are no longer in sync. And there are now lighter colored patches on the right as well, towards the bottom mostly, and sometimes I see a little swelling. I am waiting for the results of a biopsy in an other region of my right breast, but I am more concerned about the changes to that nipple that has never been biopsied. Would a simple cyst cause these changes? Is it normal? The variation seems to be great. Thanks very much!
