If they are doing a core needle or fine needle biopsy on the breast lesions, they’ll probably use lidocaine to numb the skin beforehand. Lidocaine is used when cuts on other parts of the body are stitched and probably used by your dentist. It has a sting initially, my radiologist said it might be for 20 seconds, but it was not that long for me. I joked with her that it’s the same length of time we’re supposed to wash our hands so I was going to sing the Happy Birthday song so I know when the 20 seconds would be up.

If they’re doing a biopsy of the lymph node, check with them to see if you should take a pain reliever before the procedure, like at home a few hours before. It evidently makes a big difference in comfort levels - but I didn’t have one so I’m only repeating what I’ve heard.

Other than that, I don’t know of anything to do or ask before the biopsies. Once they look at the type of cells, they’ll know more. And that’s when you might have more questions.
