Bone Tumor

Bone tumor is tumor which occurred in bone tissue (bone, cartilage, and periosteum), or its affiliated organizations (bone marrow, fat, vascular and nerve), mainly include osteosarcoma, chondrosarcoma, fibrosarcoma, multiple myeloma, chordoma, such as reticular cell sarcoma. Bone tumor of the main symptoms and signs have anemia, fatigue, malnutrition and cachexia. Local pain and tenderness as the most common, with mass at the same time or before the emergence of a small start pain, dull pain was intermittent, and then into a continuous pain. Reach the superficial part of the expansion deformation of bone and soft tissue mass, nervous light, skin temperature increased, leading to higher short-term mass dysfunction, skeletal deformities and pathological fractures. According to the nature of bone is divided into a benign tumor (well differentiated tumor cells, many local development, no transfer) and malignant (tumor cells infiltrating the growth of bad sister, prone to transfer or recurrence) the two types. Between a small number between benign and malignant, is a middle type.

Originated in the skeletal system, said the primary bone tumor. From other organ or tissue of the tumor from the blood circulation to the bone, or from the adjacent bone of both organizations said the invasion of secondary bone tumor. The cause of bone tumors is still not clear enough, but some carcinogenic substances or radiation may be a long-term radiation-induced osteosarcoma; deformity osteitis could be developed for malignant bone tumor; and multiple osteochondromatosis with genetic characteristics. Although some bone diseases is a true tumor, but its damage to bone and tumor is similar to collectively neoplasia, but also into the framework of bone tumors.

The incidence of bone tumors of all tumor of 2 ~ 3%. Benign bone tumor slightly more than that of primary malignant bone tumor in a benign osteochondroma (about 1 / 3), giant cell tumor of bone (about 20%) and common chondroma; primary malignant bone tumor to osteosarcoma (about 35%), chondrosarcoma (15%) and fibrosarcoma common, bone marrow-derived tumor accounted for only 10 ~ 15%. In some tumors, the occurrence of white and black but there is also significant differences, indicating the occurrence of bone tumors and racial and Parent Living environment. Although the course of any age, any bone tumor of bone may happen, but the primary bone tumors occur in 10 to 30-year-old strong bone development or growth period, while the transfer was particularly prevalent in the 40 to 50 years of age. Cancer happened on the primary tumor site is good hair long bone in the limbs, lower limbs than upper limbs, and bone occurred in the knee area of the tumor for more than half of the total; and watch metastatic tumor found in spine, pelvis, ribs and proximal limb bones.
