My daughter has developed bone cancer. what is it exactly?

Try to get details..: Specifically, bone cancer is a type of sarcoma. It is more common in children/ young adults and usually one hopes to detect it early enough that surgery and / or radiation would be helpful. Other confused diagnoses with this term improperly used are cancers that start someplace else and spread to the bone (breast cancer for instance) or cancers of the bone marrow (leukemia).

I am sorry to hear: Bone cancer is not common diagnosis, the cancer could originate from the bone itself or the cancer could come from place else and move to the bone. Good luck, thank you.
