Thu, 22 May 1997 07:21:47 +0000 Dear Ilene Regarding your under arm lump it could well be breast tissue! Many or most women have breast tissue segments which are wing shaped in the anatomy books called a "Tail of Spencer". I have known a pregnant woman to have it biopsied more than once, under the orders of an obstetrician and at a specialist breast clinic! Try applying treatments for blocked ducts to this area!
