Ewing’s sarcoma is a very rare type of malignant tumour that grows in bones or the soft tissue around the bones, such as cartilage or the nerves. It usually affects people from the ages of 10 to 20 and has a high rate of being cured. Children with Ewing’s sarcoma that hasn’t spread have cure rates as high as 80%. Even if the treatment works, patients still need to follow up for many years. Ewing’s sarcoma can return even a decade after the diagnosis.
