Is there a difference between osteosarcoma and bone tumor, is osteosarcoma bone cancer

Bone tumors are divided into benign and malignant, osteosarcoma is only one of them, which is a malignant tumor, mostly occurring at the lower end of the femur and the upper end of the tibia of the lower limbs. Suggestions: If you want to rule out osteosarcoma, you need to go to the hospital for a complete examination, osteosarcoma usually needs to check for blood sedimentation rate, alkaline phosphatase, etc., and simple leg pain can be caused by many reasons, it is recommended to complete the examination to make a clear diagnosis.

The main difference is that osteosarcoma is related to bone tissue, while epithelioid sarcoma is generally found in hollow organs, blood vessels, lymphatic vessels, etc. In reality, the difference between epithelioid sarcoma and osteosarcoma is pathological examination, and tumor cells can be observed by smear with different morphology and different tissue structures.

Bone tumor is a big concept, including benign tumor and malignant tumor, osteosarcoma is one of the bone malignant tumors, the degree of malignancy is high, so the two concepts cannot be compared.

To distinguish osteosarcoma from metastatic bone tumors, it can be distinguished by:

First, the population of the disease is different. The incidence of osteosarcoma is generally adolescent, and most of them are male. Metastatic bone tumors are more common in middle-aged and elderly people, and patients with metastatic bone tumors will have a history of primary tumors.

Second, the site of occurrence is different, osteosarcoma generally occurs at the bone end of the limbs, mainly the rapidly growing metaphysis. Metastatic bone tumors can occur anywhere in the body, but they are more common in the spine and can also occur in the extremities.

Third, PET-CT can be performed to determine the primary lesion of metastatic bone tumor and whether there are other metastases.

Question 1: What is the difference between osteosarcoma and bone cancer Osteosarcoma is a malignant tumor (cancer) with a relatively low degree of tissue cell differentiation, and it is also the most malignant bone cancer.

Question 2: Is osteosarcoma more serious than bone marrow cancer? Hello, according to your description, osteosarcoma is a malignant tumor that is prone to metastasis. It can be said to be very serious and requires aggressive chemotherapy, local radiation**, and cut-off if necessary**.

Question 3: What is bone cancer Oh my God, I don't know what kind of answer I see!!

There is no such thing as bone cancer, to be precise, it should be called osteosarcoma, and cancer refers to the malignant tumor of the epithelium!

Osteosarcoma, also known as osteosarcoma, is a malignant bone tumor that occurs more commonly in adolescents or children under the age of 20, and is the most common among pediatric bone malignancies, about 5% of pediatric tumors.

The prominent symptom of osteosarcoma is pain at the site of the tumor, which is caused by the erosion of tumor tissue and the dissolution of the bone cortex. The main manifestations are:1

Pain 2As the disease progresses, the mass may become swollen locally, and the lump may be palpable in the painful area of the limb with significant tenderness. If the lump grows rapidly, the lump can be found from the appearance of the leak.

The surface of the mass is warmed and superficial veins are exposed, and there may be varying degrees of tenderness on the surface of the mass and in nearby soft tissues. 3.Limp 4

At the time of diagnosis, the general condition is generally poor, with fever, malaise, weight loss, anemia, and even failure. In some cases, the tumor grows rapidly, and lung metastasis occurs at an early stage, resulting in a deterioration of the general condition. Pathological fractures at the site of the tumor make the symptoms more pronounced.

Osteosarcoma is still a disease with a high mortality rate among children and adolescents, but early detection and timely** have greatly improved the survival rate of the disease.

After the pathological diagnosis of osteosarcoma is confirmed, the early chemical or radioactive treatment begins**, and the removal of tumor tissue is an important step in osteosarcoma**. With the improvement of surgical oncology technology and the development of endoscopy research, limb preservation has shown a good prospect. Consolidation chemical or radioactivity** after resection of tumor tissue is important to control tumor metastasis and improve survival.

Osteosarcoma should be surgically surged. If possible, local wide excision can be done to preserve the limb. In addition, a biopsy should be performed prior to amputation.

The classification of osteosarcoma is mainly based on the pathological classification, generally according to the degree of malignancy of osteosarcoma, when there is periosteum osteosarcoma in general, or extraosseous osteosarcoma, which is relatively low in the degree of osteosarcoma, and some of us now osteosarcoma, and some of the higher degree of malignancy, telangiectasia osteosarcoma, etc., these types are different subtypes of osteosarcoma, so this is to be determined according to the results of pathology.

No matter what kind of osteosarcoma is caused by irregular diet and poor mood caused by meridian blockage, the root of the first is to dredge the meridians and change the physique.

Transmission of osteosarcoma.

The classification method is to divide into bones.

Attack sarcoma and paracortical osteosarcoma. Recent studies have shown that the classification of osteosarcoma has changed greatly, mainly because the clinical, radiological and histological aspects of osteosarcoma are not the same. At present, there is no unified and acceptable method, and the following classification of osteosarcoma is based on the WHO (2002) classification of bone tumors, which is divided into five categories:

Intramedullary high-grade osteosarcoma, intramedullary low-grade osteosarcoma, proximal cortical high-grade (high-surface osteoma) osteosarcoma, proximocortical moderate chondroblastoma (periosteal osteosarcoma), proximalcortical low-grade osteosarcoma (paraosseous osteosarcoma). Among them, intramedullary high-grade osteosarcoma can also be specifically divided into: osteoblastic osteosarcoma, chondroblastic osteosarcoma, fibroblastic osteosarcoma, mixed osteosarcoma, small cell osteosarcoma, and other telangiectasiatic osteosarcoma.

Osteosarcoma is one of the most common malignant bone tumors and is very malignant. It is more common in adolescents and occurs at the metaphyseal end of the distal femur, proximal tibia, and proximal humerus. The main clinical manifestations are localized, persistent, and worsening at night, accompanied by a systemic cachexia state or limited movement of nearby joints.

Elevated epidermal temperature and venous distension may be found on the surface of the tumor. X-ray shows a distinct periosteal response and an aggressive development, with a Codman triangle or a "daylight" pattern. In addition to conventional**, it is recommended to inject Japanese WT1 tumor vaccine with antigen to enhance or induce the body's immune response to tumor cells, and use broad-spectrum WT antigen to prepare anti-tumor vaccine to promote T lymphocyte proliferation, activation and cytokine release.
