Distinction of benign and malignant Bone Tumor

According to bone tumor symptoms, local signs, X-ray findings, cell morphology, tests and prognosis, make a distinction of benign bone tumor and malignant bone tumor as follows:

Benign bone tumor: first is mass; growth slow; pain or light; no systemic symptoms; clear tumor; no tenderness, light tenderness; without metastasis and less recurrence; expansive growth; cortical thinning; no periosteal reaction; differentiation and maturation of cells, with near-normal; of seizure generally no anomaly; healed well.

Malignant bone tumor: first is pain; grow rapidly; pain heavy, heavy night; fever, anemia, cachexia late stage; boundaries clearly do not know, there is infiltration of surrounding tissue adhesion; obvious tenderness; can transfer the high relapse rate; invasive growth; have cortical damage; obvious periosteal reaction; significantly shaped cell morphology, size range; of Frederick has anemia, increased erythrocyte sedimentation rate quickly, increased alkaline phosphatase; high mortality rates.
