Information About Bone Cancer

Bone cancer, it is a malignant tumor that affects the skeletal system of the body. Some cases of bone cancer are mostly caused by malignant tumors that are directly caused in the bones. These tumors are malignant primary. In contrast, malignant tumors metastasized elsewhere occur in the body, and then penetrate into the bones, usually in the blood or lymphatic system. Malignant tumors are including osteosarcoma bone, cartilage cell chondrosarcoma, fibrosarcoma and malignant fibrous elements support fibrohistiocytomas and lymphomas and Ewing's sarcoma of the bone marrow. Even though all of bones are susceptible to be infected by cancer, the regions around the knees are easier to be infected by this cancer Malignant tumors are most common primary bone osteosarcoma, which are slightly more common in men than in women.

The classic symptom of osteosarcoma is a mass more slowly. Although it is painful to touch, the tumor itself is usually marked by a dull discomfort is during the night. As the tumor grows slowly, cancer often progresses very far before it is diagnosed.

The diagnosis can be achieved by various means. X-ray examination showed a structural change over the end of the bone and often abnormal bone formation in the tumor mass. Bone scintigraphy, a process that assesses the uptake of radioactive material injected into the bone, would be positive, shows active bone formation. In addition, computed tomography show the enlargement of the outside or cortex, the bone with a soft-tissue mass outside the bone. Finally, people who are infected by this type of cancer can be diagnosed by using X-ray examination procedures to identify the use of dyes for the affected arteries to determine the extent of the tumor. In osteosarcomas ultimately transferred from blood into the lungs, the chest x-ray for the detection of metastases is essential.

The most important diagnostic test is the biopsy in which the tissue is taken for analysis. When the bone cancer exists, the microscopic examination of tissue showed abnormal cells produce bone mineralization.

The program for the treatment of bone cancer is generally based on the knowledge that over 80 percent of patients have secondary tumors in other parts of the body at the time of diagnosis. In addition, affect bone metastases cause pain and can lead to a whole body structural weakness that caused bone fractures. Tumor control in the whole body is also important that local control. Bone metastases often respond to radiotherapy. Most cancer centers are also receiving chemotherapy, the small blood-borne metastasis, when surgery is performed to destroy locally. Local tumors by amputation of the upper member of the tumor or removal of the tumor area preserving intact part are rooted out. The preservation of the branch is only possible when the tumor is detected before it has attacked the nerves and blood vessels surrounding.
