Who is affected by osteosarcoma?

This information has been written for patients, their families and friends, and the general public to help them understand more about chondrosarcoma: what it is and the different types. This information is produced in accordance with BCRT's information policy.

Osteosarcoma can affect people of all ages but is mostly found in older children, teenagers and young adults between the ages of 10 to 24.

There is also a smaller group of people over the age of 55 who develop osteosarcoma.

  • In the UK around 160 people are diagnosed with osteosarcoma each year. This is fewer than 3 people out of every million people in the population, this is known as the ‘incidence rate’ (2.6 per 1,000,000 people).

  • Around 11 cases of osteosarcoma are diagnosed in the Republic of Ireland each year.

  • Osteosarcomas affect males slightly more than females (approximately 1.4 times more often).

  • Osteosarcoma tends to occur at an earlier age in girls than in boys. This may be because girls have a growth spurt at a slightly earlier age.

The study of how often diseases occur in different groups of people and why, is called epidemiology (EH-pih-dee-mee-OL-loh-jee).
