Hey. My name is Oliwia. I'm 10 years old. At fall 2015 I was diagnosed with cancer of the hip bone . I am treating in the Oncological Surgery Institute of Mother and Child in Warsaw . Due to illness I will have a long and intense treatment. I went through 6 cycles of preoperative chemotherapy and in April 2016 surgery to remove the tumor and the insertion of the hip prosthesis. In August 2016 I ended 25 cycles of radiotherapy . It is still continuing in the post-operative chemotherapy Warsaw. I will go through long and intensive rehabilitation , which will allow me to return to health. It is associated with high financial costs . Many thanks to everyone for any help and support. Olivia & parents .
