risk of spreading
what is a metastatic tumour?
secondary tumour that grows in a different location to the primary tumour
where do metastatic tumours typically grow?
in areas of high blood flow e.g. lymph nodes
what type of tumour is leukaemia?

what are the main types of leukaemia?
acute and chronic
which type of leukaemia is more commonly diagnosed?
acute - chronic is usually an incidental finding
where does lymphoma occur?
in the cells which make up part of the immune system - B and T cells
how are haemopoietic tumours treated?
chemotherapy - highly responsive
how are sarcomas classified?
according to their parent tissue
where are osteosarcomas typically found?
distal radius
proximal femur
are osteosarcomas typically benign or metastatic?
metastatic - usually has occurred by the time of presentation
how is osteosarcoma treated?
surgery to remove affected limb
chemotherapy, biphosphates, radiation therapy all useful
what are the main types of sarcoma?
osteosarcoma
haemoangiosarcoma
soft tissue sarcoma
where do haemangiosarcomas typically affect?
spleen, heart/blood vessels
how are haemangiosarcomas treated?
combo of surgery and chemotherapy
what is a soft tissue sarcoma?
tumour of the connective tissue
