Welcome to healthcaremagicInverted nipple
can be due to so many different causes.This includes congenital,trauma ,infection caner etc. Although breast cancer
is one of the cause of nipple invertion,it is not the only cause.
Since your mammogram
was done recently and it doesnot show anything abnormal you can be assured that it is not serious. Plastic surgery
can be done if you opt to correct it.
But you need to have your mammogram routinely as prescribed to follow your nipple and cyst.
