I hope all went well for you today. I have been having different appointments lately over the same type of thing. I have had about 5 of those darn lumps taken out over the years. there has never been anything but solid lumps which have all checked out ok. Here the last 6 yrs they have been keeping a (close, yeah right) eye on it. just this past week I found out that I have 4 of them. I talked to a surgeon about them and we are going to leave them alone. I dont' worry until they tell me to worry.
those mamograms are such a pain, I hate to do them. they always have to do them twice saying they got to go tighter.
I now tell them when I can let go and lean backwords and not fall down it will be tight enough.
I pray you get a good report from them. Good luck.
