Hi, the surgery to put the port in was pretty easy for me. I did it at a private hospital and they gave me two types of sedatives. I didn't feel a thing. It was a pretty quick op too. Make sure you ask what sedatives they will give you (not just local!).
I've had fine needle biopsies but I actually thought they weren't as reliable as core biopsies. Needle biopsies were the easiest I thought - as they are fine needle. Though I think they may take up to 3 samples from each area. I've also had a vacuum assisted biopsy which was by far the worst. Just ask for local anaesthetic if you are worried about it.
