This week I went to the breast clinic after being referred because of a lump in my armpit. I've been previously for a lump in my other armpit which turned out to be benign breast tissue. They thought this was probably the same so I am not overly worried but they decided to do a core biopsy to be on the safe side, partly as I'm 20 weeks pregnant. 

I found the biopsy a really difficult experience although the medical staff were all wonderful, but since taking the dressing off I've realised that where they took the samples from isn't really anywhere near the lump in my armpit, the samples were taken more from the side of my breast. I don't know enough about the procedure to know if this is how it's done, or if they intended to take samples from there to check the breast. But the little scars are a good inch or two from where the lump is, the radiologist who did the biopsy wasn't the person who did the scan. I'm now just fretting that if everything comes back clear I will still be worried that they've sampled the wrong area. Or that I will have to have the biopsy again, which is obviously the right option but fills me with dread. 

Anyone had a similar experience or can explain better how the biopsy works and if I'm over-thinking?
