I have inverted nipples and an uneven lump. what does this mean?

Need to be checked: If the inversion of your nipple is recent especially if it is associated with a breast lump you definitely need to see a breast care specialist for further evaluation and to check for possibility of a malignancy. If the inversion has been a long standing issue and if the lump is in your other breast they may not be related; but still you need to be medically checked. Do not procrastinate.
