Osteosarcoma, also called osteogenic sarcoma, is a type of cancer that develops from bone. Osteosarcoma is destructive at its original area and is likely to spread to other parts of the body. Osteosarcoma is a malignant (cancerous) tumor that arises from bone itself, and is thus called a primary bone cancer. Primary bone cancers are relatively rare overall.

There are numerous theories regarding the causes of osteosarcoma. Many cases occur during a time of rapid bone growth, as in teenagers or people with Paget's disease. This suggests that the cancer may develop when the body loses its ability to control the multiplication of certain bone cells. Some cases of osteosarcoma are likely to have a genetic basis, and numerous genetic abnormalities have been found in patients with osteosarcoma. Osteosarcoma is also the most common second cancer to develop in survivors of retinoblastoma, a cancer of the eye that often has a genetic cause. Other cases arise in people who have been exposed to radiation, either accidentally or as part of a medical treatment.

The most common early symptoms of osteosarcoma are often vague. There may be pain or swelling at the site of the tumor, but these symptoms initially may not seem serious in a young, active person. Thus, the patient or medical personnel may attribute the symptoms to growing pains, or an injury from sports, for example, and the diagnosis may be delayed. Eventually, it is usually possible to feel a firm lump on the bone, and this lump will be uncomfortable to the touch.-

I have given details about Osteosarcoma above and the child should only feel pain and swelling. No other serious symptoms will be noticed -
