Can breast tissue from under the armpit be removed and transferred back to the breast?

I've got some breast tissue that is located in my left armpit and it swells up before my period just like the tissue in my breasts. My question is, if I were to get this removed from under my arm, would the surgeon then be able to put that tissue back into my left breast? That would be ideal as my left breast is a bit smaller than my right breast. Also how did the breast tissue get under my armpit in the first place?
