Other solid tumours
Solid tumours are solid, at first localised lesions that form a swelling. They can originate from any tissue, organ or organ system, respectively. Solid tumours can be benign or malignant. Following brain tumours (tumours of the central nervous system), most frequent are tumours of the sympathetic nervous system (neuroblastoma) accounting for 8 %, soft tissue sarcomas (especially rhabdomyosarcoma) with 6 %, and kidney tumours (Wilms tumour or nephroblastoma, respectively) accounting for about 5.5 % of all cancers in children and teenagers. Less frequent are germ cell tumours, eye tumours (retinoblastoma), bone tumours (osteosarcoma, Ewing sarcoma) and liver tumours (hepatoblastoma and carcinoma).
