What kind of disease is osteosarcoma

What kind of disease is osteosarcoma? Osteosarcoma is a common malignant bone tumor. Its occurrence can cause great harm to patients. Therefore, after suffering from osteosarcoma, everyone must receive timely treatment. In order to detect the symptoms of the disease in time, we need to understand specifically what kind of disease osteosarcoma is.

Osteosarcoma, also known as osteogenic sarcoma, is a common malignant bone tumor that occurs in adolescents or children under the age of 20. It is the most common bone malignancy in children, accounting for about 5% of pediatric tumors. The typical osteosarcoma originates from the bone. Another completely different type of osteosarcoma is the osteosarcoma that is parallel to the bone cortex and originates from the periosteum and nearby connective tissue. The latter is less common and has a slightly better prognosis.

Osteosarcoma is the most common type of malignant bone tumor. It develops from the mesenchymal cell line. The rapid growth of the tumor is due to the direct or indirect formation of tumor bone-like tissue and bone tissue through the cartilage stage. Under the influence of external factors (such as viruses), the weight-bearing bones of the lower limbs cause cell mutations, which may be related to the formation of osteosarcoma.

As the disease progresses, local swelling may occur, and a lump may be felt at the painful part of the limb, accompanied by obvious tenderness. If the lump grows rapidly, the lump can be found from the appearance. The skin temperature on the surface of the lump increases and the superficial veins are exposed. There may be varying degrees of tenderness on the surface of the lump and nearby soft tissues. The hardness of the lump varies due to different degrees of ossification. As the lump grows, it causes limited joint movement and muscle atrophy.

After osteosarcoma is diagnosed by pathology, early chemotherapy or radiotherapy begins. Resection of tumor tissue is an important step in the treatment of osteosarcoma. With the improvement of tumor surgical technology and the development of implant research, limb preservation therapy has shown a good treatment prospect. Consolidation chemotherapy or radiotherapy after tumor tissue resection is very important for controlling tumor metastasis and improving survival rate.
