C.P.
well i rarely hear this term/type of cyst, but i am a 30 something mom now and i had one myself which was removed from my right temple when i was around a year old. no ill effects and certainly technology was under-developed 30 years ago so you should be in super safe condition to have this done. and the good news is, like me, she won't ever remember it and will only have her mom to tell her that it happened!!
