Does removal of extra nipples cause any side effects and does it affect your hormones and cause any health issues down the road?

I have extra nipples under each armpit along the milk line & was thinking of getting them removed. I have a feeling there might be breast tissue underneath as they look like mini nipples and protrudes/hangs out of my tank tops at the underarm area. I'm worried & wanted some peace of mind that removal is ok and is a right decision to make. I'm embarrassed by it but don't want to jeopardize my health or have side effects due to removal. I've had them since birth. Any info is greatly appreciated.
