    A young lawyer named Gabriel Massote, from Uberlandia, a city in southeastern Brazil, was diagnosed with blood cancer at age 26. He had chemotherapy(化疗)for almost a year. However, his cancer returned in a worse form, so he had to receive a bone marrow transplant(骨髓移植)。

Brazilian news medium Sempre Familia shared his story. It said how over 1, 000 miles away, in a small town in the state of Rondonia, an unemployed hairdresser named Elza dos Santos came across a series of posters near a supermarket in the city of Ariquemes and went to see what they were about. After learning about the whole thing, Elza signed up as a donor.

Just when the possibility of Gabriel's finding a match in the Bone Marrow Donor Registry in Brazil was about1 in 100, 000, he was blessed. In Rondonia, Elza was informed her marrow was a match for that of a person in need of a transplant and she didn't say no.

She traveled to Rio Grande o Norte, on the opposite side of Brazil, for the transplant. The first attempt didn't work. Elza was called again and she immediately made a second trip in order to repeat the process. Gabriel, now 35, concludes, "She saved me twice, and today my blood cells are Elza's. "

Deeply grateful, Gabriel wanted to find the donor. "When I met Elza and found out that she and her husband were unemployed and living in borrowed space, I was sure I should help them. "The lawyer started a campaign online and soon 465 people donated about$28, 500. Thanks to this generosity, Elza and her family bought a house.

＂I was just a drop of water in the life of this young man, but today he's the whole ocean in my life, "Elza told Sempre Familia.
