Uncontrollable division of cells present in the tissue leads to the formation of a lump or mass of tissue. This mass of tissue is known as a tumor and when this condition is diagnosed in the bones of a human body, it is known as bone tumor. Most bone tumors are non-cancerous (benign) and cannot grow. However, it is still possible that the bones could be weakened and the condition could result in fractures and other such problems. The tumor replaces the normal and healthy tissue.
It is observed that cases of malignant bone tumors are much less as compared to benign tumors. Some examples of benign bone tumours include:
1. Giant Cell tumor: In this condition, the tumor affects the legs
2. Osteochondroma: This form is most common among teenagers
3. Osteoblastoma: A tumor which develops in young adults and affects the spine
4. Osteoid osteoma: A tumor that affects long bones
5. Enchondroma: Usually found in hand and feet.
As stated earlier, metastatic cancer is a form of cancer that spreads to the bone from other spots in the body. Cancers from other parts that commonly spread to the bones include breast cancer, prostate cancer and lung cancer.
