What causes Ewing's sarcoma cancer?

Cancer is caused by genetic mutations. The genetic mutation can be passed on from a parent, or it could be a genetic mutation that is acquired during the course of a person's life. Environmental contaminants and viruses are two examples of things that cause acquired mutations.

Answer and Explanation:
Ewing's sarcoma is a type of bone cancer. The cause of Ewing's sarcoma is not always clear. There is no proof it is genetic. There is a theory that Ewing's sarcoma is the result of chromosomes 11 and 12 exchanging genetic material and causing cells to divide excessively.

Bone cancer is the growth of abnormal cells in the structural tissues of the bones. Although bone cancer is extremely rare, the most common types are osteosarcoma, chondrosarcoma, and Ewing sarcoma. These begin in the bone tissue and are thus classified as primary bone cancer. If cancer spreads to the bones from other parts of the body, it is called metastatic bone cancer.

Bone cancer affects the body in many different ways. First, the cancer cells can absorb more of the body's nutrients, leading to weight loss as the body struggles to provide fuel to the noncancerous cells. Often, this requires the consumption of stored energy from fat. Second, bone cancer can cause swelling and pain around the affected area as the growth of tumors presses on the surrounding bone tissue, even fracturing the bone. Third, bone cancer can cause brittle bones by absorbing the minerals needed by normal bone cells to maintain bone strength. Finally, if the cancer metastasizes to other parts of the body, it can develop tumors in any of the other organ systems.
