• peak ages are 10-20, but younger children and older adults can also get it
• half are under 15 years
• less common before 5 or after 30
• no known cause
• cells in the tumours have a piece of chromosome 11 moved to chromosome 22
• 85% contain chromosomal translocation at the t(11;22)(q24;q12)
• the genetic change occurs only in the tumour cells, not in the sperm or egg
• 2.5% of cases of childhood cancer
• development of the tumour appears to be in some way related to periods in life with rapid growth, hence the average for tumour development is 14-15 years
• slightly more common in boys than in girls
• most common early signs are pain and swelling
• can spread to other parts of the body
• always requires treatment to the whole body (chemotherapy, surgery, radiation therapy)
