What is the soonest a person can get results back from a breast biopsy?

I went to my primary physician because I had a rash under my breast, an uncomfortable feeling under my left arm, a little tenderness, a heavy feeling. She gave wrote me a prescription for the rash, told me to use an anti fungal powder and to try and keep my breast dry underneath which is nearly impossible to do. She felt around under my arm but said she didn't feel anything but said she would order a sonogram and I said that was fine. This uncomforable feeling had gone on for several months and I was getting tired of it. Let me say that I did have a mammogram the first of this year and it was normal and a check up with my GYN doctor and she also checked my breast and didn't feel any lumps. I check my breast regularly and I haven't felt any lumps either and couldn't feel these so this is something that was a complete surprise - READ ON.....

I went for the sonogram on Monday morning, which didn't take the tech long, she took it directly to the dr/radiologist and he immediately ordered a mammogram. I didn't think anything of it as I thought he was just trying to get a picture of my underarm, but when he came back an wanted a different picture of my breast then I began to think something. After that second set of films of my breast, he ordered a sonogram of my breast and then another sonogram with him watching so he could see the masses as she did the sonogram. When she was finished he told me he showed me what he was looking at and what he felt the sonogram was showing and that these places needed to be biopsied. He asked me if I could come back that afternoon to get it done which of course I did. They told me it would take a couple of days to get the results. It will be a week this Monday. Does anyone know if this is normal? We have postponed a trip because of all of this. My husband doesn't get paid when he doesn't work so we figured if I was going to have to have any kind of surgery then he would need to take the time off then. Can anyone give any help, suggestions etc. Does anyone know the process once a person is diagnosed? Does a person always just get a lumpectomy or is there an option to have the whole breast removed and just get a new one - like smaller. I am 65 yrs old - and if this is cancer - I don't want the chance of having to do this again. I would rather have the breast removed, and have another one put there and have my other one done also. The ones I have aren't so hot - ya know???

Thanks for any help, any one can give.
