Ilona is 16. She was diagnosed with osteosarcoma 10 months ago, in July 2020 in the middle of pandemic. She was initially treated close to her home in Krasnodar krai in Russia, but osteosarcoma is a difficult, insidious cancer and it requires specialized treatment that was not available for Ilona locally. In September, her parents took her to Helios hospital in Germany. Unfortunately, Ilona’s left leg had to be amputated, and she also received seven cycles of chemotherapy. Although Ilona is approaching the final stages of treatment, she still needs to get a prosthesis that will cost over 50,000 euros. Her family’s financial resources are exhausted – they sold their family home and a car – and they need our help. Please help Ilona complete her treatment!
