@eggbert It was a cyst that my sister found - very early breast cancer beneath it.  Surgery in 1982 - radical mastectomy as the surgeon was concerned about messing about (this was the time that they were beginning to do lumpectomies).  She was also told that there was nothing to worry about prior to the op.  (I can remember her saying that her GP had referred both her and another young woman that week and both of them ended up with a bc diagnosis.)  From memory, her boys were about 4 & 6 at the time (or close to if not that).  Unfortunately, although she made the 5 year all clear mark, it came back aggressively around 8 years and she died in 1999.  It was identified as oestrogen positive and she was one of the early ones on Tamoxifen but I think that it was too little, too late, by then.  I've missed her since then but recently there have been so many things that I wish that I could talk to her about.  

I know that she would have appreciated the support on this network, as I have.  I'm glad that you have found your way here.
