Alternative Names

Supernumerary nipples are fairly common. They are generally unrelated to other conditions or syndromes. The extra nipples usually occur in a line below the normal nipples. They are usually not recognized as extra nipples because they tend to be small and not well-formed.


  • Variation of normal development
  • Some rare genetic syndromes may be associated with supernumerary nipples

Home Care

Usually, no treatment is needed. The extra nipples do NOT develop into breasts at puberty.
