Is nipple inversion a sign of breast cancer?
A number of conditions may cause nipple inversion. Nipple inversion that has been present since puberty or following pregnancy is unlikely to be cancerous.
However, you should visit your GP straight away if your nipple inversion develops suddenly or if there are any sudden changes to your nipple inversion. Your GP needs to investigate these changes as they could indicate an underlying medical problem such as inflammation or breast cancer.
