I tested positive for the BRCA 1 gene and my OBGYN gave me a list of hospitals to go to for the prophylactic surgeries. She listed Cornell, N.Y.U., Mount Sinai, and Columbia. Call me dense but when I google Cornell I get New York Presbyterian and when I google Columbia I get New York Presbyterian as well. Could someone please spell it out for me...which hospital is which?!? -Thank you in advance!!
