Help an Islander Survive Fibrosis Dysplasia

My name is David Araya. My wife´s name is Renata Andrea. I am Costa Rican and she is Mexican and we live in Isla Mujeres, Mexico. We married March 11th, 2020 in hopes of living a happily ever after. A lot of people say Isla Mujeres is paradise but for us it has turned into a dark and very scary place. My wife has been diagnosed with fibrous dysplasia rare disease and must be treated immediately or else run the risk of it becoming cancer and spreading to the rest of her body. Her operation is programmed for saturday December 5th and is an immense amount of 50.000USD. We´ve been able to gather almost 20.000USD but are still missing a large sum. Please help. 

P.S I have all Dr.´s quotes, estimates, additional exams that must be done. Travel expenses, etc for proof. Whomever wants to see them, I can definitely share it.
