13 year old boy have bone cancer

Hi everybody! My 13 year old cousin has been diagnosed with bone cancer on his left hip. Few months ago he was getting a wrong treatment (6 sets of chemotharapy) in Kazakhstan which lead us to ask help from German doctors. By the time we collected more than 100.000 € and got to Groshadern Klinik in Munchen doctors said that it's too late and he needs an amputation which was done on 12.03.17. After that he got one course of chemotherapy and analyses came bad, on 01.10.18 doctors made second surgery on same leg. Now x ray showed that cancer metastased in lungs. We do not loose the hope because he is very young and strong, just he's body is very tired after 2 surgeries and 7 chemotherapies. We need money to continue treatment in Germany because there is one more surgery on lungs and another course of chemotherapy to consolidate a result and finally beat this cancer. We really appreciate any help, any amount, any coin matters for us. If you can't help financially please pray for him. Thank you so much. God Bless You and Your Family. https://www.instagram.com/help_sos_aldiyar This is my cousin's Instagram help page
