Bone or cartilage mass epidemiology and demographics

Bone and cartilage tumors are uncommon, they represent 0.2% of all neoplasms in general population. The prevalence of bone and cartilage tumors is approximately 0.9 per 100,000 individuals. Bone and cartilage tumors have a bimodal age distribution. These tumors are more frequent in children and adolescents, and older adults. The average age at diagnosis is between 10-25 years old and 60-75 years old. Males are more commonly affected than females, with a 1.5:1 ratio.^[1] Bone and cartilage tumors are slightly more common among individuals of Caucasian race.^[2]
