Help save Karolina's life

Karolina is a single mom of an 8 year old boy. She has just been diagnosed with terminal bowel cancer. She lives in Poland, but the only treatment that could potentially save her life, or at least give her a bit more time to spend with her son, is in Germany. 
She not only needs to pay for the treatment, but also to stay in Germany. We are a group of friends of Karolina and we need your help to save her life. Any donation will be highly appreciated.
