If you have a breast biopsy does the needle go threw your nipple or breast?

Not the nipple: A needle biopsy of a breast mass would not need to go through the nipple. However the only way to biopsy the breast is by going through the skin over the breast and the breast tissue between the skin and the lump.

Breast: A needle biopsy of a breast mass goes through the breast tissue as close to the lump as possible, not through the nipple.

No: No, it wouldn't go through the nipple. The needle will go into the breast, but it won't go all the way out the other side.
