Accessory breasts, also known as polymastia, supernumerary breasts, multiple breast syndrome, or mammae erraticae, is the condition of having an additional breast. Extra breasts may appear with or without nipples or areolae. It is a condition and a form of atavism which is most prevalent in male humans, and often goes untreated as it is mostly harmless. In recent years, many affected women have had a plastic surgery operation to remove the additional breasts, for purely aesthetic reasons.

A related condition, in which extra nipples form, is called "supernumerary nipple" or "polythelia".


In some cases, the accessory breast may not be visible at the surface. In these cases, it may be possible to distinguish their appearance from normal breast tissue with MRI.[1] In other cases, accessory breasts have been known to lactate, as illustrated in a woodcut showing a child nursing at ectopic breast tissue on the lateral thigh.[2]

There is some evidence that the condition may be more common in Native American populations.[3]

In fiction[edit]

Some science fiction and comedy films have featured minor female characters with one or more additional breasts: The Warrior and the Sorceress (four breasts); Total Recall and its 2012 remake (three breasts); Star Trek V: The Final Frontier (three breasts); Earth Girls Are Easy (four breasts); Firecracker (three breasts); Flesh Gordon 2 (more than four breasts, but just on a sign); Good Luck Chuck (three breasts); Dumb and Dumberer (three breasts); Silence of the Hams (three breasts); Necropolis (six breasts); Paul (three breasts); and Star Wars Episode VI: Return of the Jedi (six breasts) (the Askajian).

The Hitchhiker's Guide to the Galaxy series features many references to "Eccentrica Gallumbits, the triple-breasted whore of Eroticon Six".

Actress Angela Bassett will play a women named Desiree Dupree afflicted with this condition who is a member of a freak show in 1952 on American Horror Story: Freak Show.
