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.
Cancer may form in the bone or spread to the bone from another site in the body. When cancer starts in bone tissue, it is called primary bone cancer. When cancer cells travel to the bone from elsewhere, it is called secondary or metastatic cancer to the bone. Types of bone cancer include:
The sooner bone cancer is treated, the more favorable the outcome. If you suspect you have this condition, contact your doctor immediately.
