What are the symptoms of osteosarcoma?

At the age of blooming, life has just begun, but it happens to be a period of high incidence of malignant tumors. If you suffer from osteosarcoma, your whole life will be covered with a layer of frost. So how do you know if you have it? The first step to judge is to look at the characteristics of osteosarcoma. Next, let's talk about the symptoms of osteosarcoma.

The prominent symptom of osteosarcoma is pain at the tumor site, which is caused by the tumor tissue eroding and dissolving the bone cortex.

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 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. The surface of the lump and the nearby soft tissue may have varying degrees of tenderness. The hardness of the lump varies due to the different degrees of ossification. As the lump grows, it causes limited joint movement and muscle atrophy.

3. Limping

Analgesic claudication caused by limb pain 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 confirmed, the general condition is generally poor, manifested by fever, malaise, weight loss, anemia and even exhaustion. In some cases, the tumor grows very quickly 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.
