What are the characteristics of osteosarcoma attacks

What are the characteristics of osteosarcoma? Osteosarcoma is common in people between the ages of 15 and 30, more common in males than in females. It often occurs in the epiphyses of long bones of adolescent patients, usually in the distal femur and proximal tibia. It is a malignant tumor. So, what are the characteristics of osteosarcoma? Let's take a look.

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

Lump: As the disease progresses, local swelling may occur. 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 of the lump surface 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. As the lump grows, it causes limited joint movement and muscle atrophy.

Lameness: Pain-avoiding claudication caused by limb pain worsens as the disease progresses. Patients with the disease for a long time may experience limited joint movement and muscle atrophy.

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.

The above is a detailed introduction to "What are the characteristics of osteosarcoma attacks". I believe that after reading it, everyone must have understood that osteosarcoma is highly malignant and has a relatively high mortality rate. Therefore, once it is discovered, it must be actively diagnosed and treated, and the time for treating the disease should not be delayed.
