Cost of surgery

Hi, Our family decided to reach out and try to help our brother Martin who is in Mexico for surgery. He has Helicobactor pylori, a bacteria in the stomach that turns to cancer if it's not treated. They were given a price of $10,000 to get it fixed before they left for Mexico, however the doctor there says his stomach is a mess and he has a hernia as well so the price has gone up to $20,000. They have half the money that they need but would greatly appreciate if anyone would be willing to help with the rest of the cost. His surgery is scheduled for Wednesday, July 19th which was supposed to be their departure before they found out that more was wrong than they thought. They have five children who really miss them already and would like them to come home as soon as possible. Any donations would be greatly appreciated ❤️
