Children identified with having an Osteosarcoma are typically ranged between the ages 8 – 16 as rapid growth of the bone plates may be one reason why this type of cancer materialises. Most cancer tumours develop in the bones around the knee, either in the distal femur (the lower part of the thigh bone) or the proximal tibia (the upper part of the shinbone), with the proximal humorous (the part of the upper arm bone close to the shoulder) being the next most common site. 

However, Osteosarcoma can develop in any bone, including the bones of the pelvis (hips), shoulder and jaw - this is especially true in older adults. Initial symptoms are swelling and pain which is very similar to a fracture or even a muscle tear. Due to the rarity of this condition it is often difficult to identify and the swelling (tumour) usually is the first real identification that something is wrong. If symptoms persist, or if you are in any doubt, please insist your GP refers you to hospital for an x-ray.
