Hi Allen, not sure if you still log on here but just read about what you and your wife are going through.  I will keep you both in my prayers.  As a word of encouragement, I wanted to let you know that your wife's story sounds incredibly familiar to my own. Similiar tumor size and diagnosis.  I also had the mastectomy although I did a double and had reconstruction.  I did chemo as advised and while it wasn't fun I tolerated it fine.  It has now been 6 years and I am in great health.  No long term problems from treatments at all.  You sound so supportive and I am sure your wife is grateful.  I truly believe my diagnosis and treatment was harder on my husband emotionally than it was on me and I think the same will probably be true for you.  The hair loss and getting used to the scars was very difficult for me in the beginning but the hair all grew back and I can honestly say I have had a complete recovery and live a very normal active life.  I hope and pray your wife has just as successful of a recovery.  Be strong and know this is just a bump in the road of life that will hopefully make you both stronger.
