To help fight cancer for my son

My son has been diagnosed with testicular cancer, which metastasized to his lungs, neck, and brain. He recently had successful brain surgery but is still fighting the rest. He is in Chile being treated at the moment, but his dreams have always been to be in Canada with his family. Friends and family are trying their best to help out in any way possible. I live in Canada, but I travelled to Chile to fight this battle with him. I am unable to work at this moment, and the bills keep pilling up. I ask for help from everyone. I am kindly asking for your help through this difficult time. Thank you.
