hi if you have pit on any weight then that could be your answer that's the simple answer. but then women do change as they get older. or if your that worried go see your doctor for a check up but can you feel any bumps when you shower best time to feel around is when your all soapy. hope this helps. good luck
my left breast has always been bigger than my right breast but now it seems that it has grown a little more. i am 66 years old and i had a mammogram recently but i also noticed that my left breast has grown slightly more over the last year or so. could this be a problem?
