my name is H. i have a 11 month old son he has a lipolma on his back ecactly like your lil gurl except his is on the left, my doctor told me yesterday. i've been researching this, which my doctor has referded me to a surgeon!!! to remove the tumor or cyst, my nerves are a wreck also. they say its very rare for babies our age to have these type things they're mostly non cancerous thank god. Im still very concerned!!!! my sons has been there for about 3 weeks that i know of. what about your lil gurl? we need to stay in touch about this it would make me feel alot better.
