Bone cancers comprise about 5% of childhood neoplasms.
Osteosarcoma, the most common sub-type, shows a somewhat irregular geographic pattern of incidence, with low rates in some Asian (Indian, japanese, Chinese) and Latin American populations.
Incidence is similar in the sexes and rises steeply with age, accompanied by an increasing proportion of tumours localized in the long bones of the legs.
Rates in the USA are higher in blacks than in whites, as a result of a higher incidence at ages 10 to 14 and of tumours of the leg bones.
The descriptive epidemiology is consistent with early observations linking risk to the amount of bone growth.
