Is giant cell tumor of bone cancer? Giant cell tumor of bone is more common in:

Answer] :d common location of bone tumors: Osteochondroma is more likely to occur in the metaphysis of the diaphysis; Bone size and skeletal tumors tend to occur at the end of the bone (lower end of the femur, tibia, and soil); Bone tumors tend to occur in the metaphysis of long bones; Osteomas tend to occur in the skull and mandible; Internal and chondroma are more likely to occur in the tubular bones of the hands and feet (within the short tubular bones); Osteosarcoma is more likely to occur in the distal femur and proximal tibia; Ewing tumors tend to occur in the femur, cavity, and fibula.

Answer: c

The incidence of giant cell tumor of bone is male-to-female: 1, the age of onset is mostly 20 to 40 years old, mostly in the lower end of the femur and the upper end of the tibia, followed by the distal end of the radius of the basal cavity, the upper end of the humerus and the spine. Because of the disadvantages, we will choose C.

Respondent sedan finch case]: Fan Qing e

Giant cell tumor of bone is a potentially malignant or benign and malignant osteolytic tumor. The age of onset is 20 to 40 years old, more females than males, and the early position of the haircuts is the lower end of the femur and the upper end of the tibia. Therefore, choose e.

Answer]: In general, bone tumors tend to occur in areas with active growth, such as the lower end of the femur, the upper end of the tibia, the upper end of the humerus, and the bone end of the long tubular bone.

Now there is a new drug, called denosumab, which can mimic the growth of osteoclasts, and can reduce the rate with surgery.

Giant cell tumors are unrealistic and give Da an undeserved false sense of security.

Its main tissue components are giant cells that resemble osteoclasts and relatively thin spindle or round stromal cells. In the past ten years, the understanding of it has been deepened. It is a locally destructive, active tumor, after scratching, there are a considerable number of cases that may be **, even malignant, and distant metastasis.

In some cases, malignant transformation occurs due to local infection, trauma, or prolonged incurability, while in a small number of cases, the tissue morphology is initially malignant, or it is essentially a malignant giant cell tumor with a large number of giant cells. Therefore, they are all called benign bone Giant cell tumor of bone is a benign tumor with malignant nature in the strict sense, and at present, the orthopedic community and pathology community still debate the biological nature of this tumor (i.e., benign and malignant).

In the past, giant cell tumors of bone were divided into three stages, the so-called first stage is benign and stage three is malignant. However, in recent years, there have also been cases of stage 1 patients** or metastases. Therefore, it is still not possible to specifically determine the distinction between good and bad bone giant cell tumors.

Strictly speaking, giant cell tumor of bone is a benign tumor with malignant nature, and at present, the orthopedic and pathological circles still debate the biological nature of this tumor (i.e., benign and malignant). In the past, giant cell tumors of bone were divided into three stages, the so-called first stage is benign and stage three is malignant.

However, in recent years, there have also been cases of stage 1 patients** or metastases. Therefore, it is still not possible to specifically determine the distinction between good and bad bone giant cell tumors.
