Bone cancer – Definition
Bone cancer is a relatively rare disease in which cancer cells grow in the bone tissue. Cancer occurs when cells in the body (in this case bone cells) divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant tumors, which can invade nearby tissues and spread to other parts of the body. A benign tumor does not invade or spread.
