Marek
Marek was diagnosed with Choroid Plexus Carcinoma, an extremely rare brain and spinal cord cancer, when he was one and a half years old after an accidental fall from the living room couch. In the following weeks he underwent 30+ hours of intense brain surgery, during which surgeons were able to remove most of the tumor in his brain. During surgeries, he received three times his body's blood volume in donated blood.
