My son Aleks was diagnosed with bone cancer (osteosarcoma). At the time of treatment had to be cut out diseased bone in the leg and insert the endoprosthesis. Now chemotherapy is over we need the money for two things1 With leg endoprosthesis rehabilitation and physiotherapy is needed at a cost2. In my family there are people with Gorlin syndrome (Nevoid basal cell carcinoma syndrome).In the future Aleks may experience the symptoms. With the diagnosis, treatment can start earlier for a more successful outcome.
