Bone cancer is a cancer type that occurs in the bones and its cause is still unknown. There are some factors that canenhance the risks of bone cancer and they include Paget's disease, previousradiation, or previous chemotherapy. Symptoms that indicate the presence ofbone cancer are different and can alter depending on the place in the bodywhere they appear. Since medicine doesn’t have the real cause for bone cancerdevelopment, we are not familiar with its causes. The thing that is known is that bone cancer isn’tcontagious, and it can’t be transferred from one person to other. As we have stated earlier, there are some risk factors thatcan lead to bone cancer, which is why some people do have more changes indeveloping bone cancer than others.
Some of the riskfactors that can be included in bone cancer development include age. For example,children and young adults have more chances in developing bone cancer than theolder ones. A person who has been treated from some condition with radiation orchemotherapy is considered to belong to the group of people who are morelikely to develop bone cancer. Hereditary factor is also important, because it isconsidered that people who have someone in their family tree with bonecancer, are at risk of getting it, too. People with hereditary retinoblastomaare also people who have predispositions for bone cancer. Hence, when a doctor is trying to diagnose bone cancer, hewill first look for information regarding patients’ age and other factors thatcan put him into one of the groups that are at higher risk.
Types of Bone CancerBenign Bone Cancer is a type, which is more common in the bonetumors that are malignant. The fact thatit can’t grow and spread and that it is not life-threatening is a littleencouraging. Malignant Bone Cancer Types are Osteosarcoma, Chondrosarcoma and Ewing's sarcoma.
