Wow, that's crazy. Seems you had a twin in the womb. You were a fighter back then and a fighter now. Praying.UPDATE, the good Lord is always right!! The Dr is pretty sure it's not cancerous!!! He said these tumors are almost always benign!! He said the teratoma is made from teeth nails and bones and been there since before I was born. It's as big as my heart and pressing against the heart. It needs to come out so big surgery coming up next week. Thank you everyone for your prayers I will need more in the coming weeks!!!
