My 14 year old daughter just found out she has a bicornuate uterus. will it cave in more over time?

Double horn: The bicornuate uterus is one of several possible defects in the normal formation of the uterus. Simply stated, a normal vagina is attached to a uterus with 2 chambers (r/l) with a silhouette more like a heart than the normal pear shape. The central division maintains the same proportions as the rest of the structure with growth. Some can have normal pregnancies in either horn, some do not.
