What are the typical symptoms of osteosarcoma?

With the acceleration of the pace of life and changes in the environment and diet, some diseases have also appeared in our lives imperceptibly. Osteosarcoma is one of them, which has attracted people's attention due to its high incidence. So let's take a look at the typical symptoms of osteosarcoma.

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 during 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. The typical symptoms of osteosarcoma are as follows:

1. Pain. Pain of varying degrees at the tumor site is a very common and obvious symptom of osteosarcoma. It is caused by the expansion of the tumor tissue destroying the bone cortex and stimulating the periosteal nerve endings. The pain may develop from intermittent in the early stage to continuous after a few weeks, and the degree of pain may increase. Pain in the lower limbs may cause pain-avoiding claudication

2. Lump. As the disease progresses, local swelling may occur, and the lump may be touched 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. The surface of the lump and the nearby soft tissue may have varying degrees of tenderness. The hardness of the lump varies due to different degrees of ossification. The enlargement of the lump causes limited joint movement and muscle atrophy.

3. Lameness is pain-avoiding claudication caused by limb pain, which worsens as the disease progresses. Patients with long-term illness may experience limited joint movement and muscle atrophy.

4. General condition. When the diagnosis is clear, the general condition is generally poor, manifested as fever, malaise, weight loss, anemia and even exhaustion. In some cases, the tumor grows very fast and metastasizes to the lungs at an early stage, causing the general condition to deteriorate. Pathological fractures at the tumor site make the symptoms more obvious.

Therefore, when our body shows abnormal signals, we must pay attention to it and go to the hospital for examination in time. Early detection and early treatment are the basis of a healthy body and a manifestation of being responsible for the body.
