yep look at location for all bone tumors, age is less important, but still helps.

location of the bone ,
in alphabatic order ,
C comes first so it will effect the proximal part of the bones . .
O in Osteosarcoma comes later so it will effect the distal part .
UFFFFFFFFF i am having the anxiety attacks again . how do you guys relax yourself from such exam tensions and anxiety attacks , including performance anxiety of the exam ?
