There are many good websites about osteosarcoma and Ewing’s sarcoma, both also called bone cancer. Here is one and here is another specifically written for teens.
It is the most common cancer in teens, although cancer in teenagers is a rare happening. They don’t really know what causes it, but it seems to be associated with growth spurts. The good news is that even if you are diagnosed with osteosarcoma, your odds of both survival and keeping the limb that was affected is quite good. There are many kids who have survived it just fine. Yes, treatment is a challenge, but most survivors say they wouldn’t have changed what they learned while going through the process for anything.
In fact, Senator Teddy Kennedy who recently died has a son, Edward Kennedy Jr., who was diagnosed with bone cancer at age 12 and has survived just fine. “These two girls“http://www.rd.com/living-healthy/two-athletic-females-survive-bone-cancer-and-receive-bionic-bones/article49294.html both were diagnosed with bone cancer, but went on to survive it and are still happy and healthy to this day.
Bear in mind that there are other more common things that can mimic bone cancer, such as an infection, or a stress fracture you didn’t know you had. There are also bone tumors that are benign and not malignant at all. Even normal growth spurts and sports injuries can make people think someone has bone cancer when they don’t at all.
Good luck. I hope you turn out not to have bone cancer, but if you do, you have a very good chance of getting through treatment and being cured. Make sure you ask all the questions you need to – in fact, it would be a good idea to write them down before you see the doctor. That way you won’t forget any. And if it should turn out to be bone cancer, consider it a learning experience, one that will teach you how strong you are and how to have compassion for others.
