Understand the symptoms of osteosarcoma

Osteosarcoma mostly occurs in young people, especially teenagers. Because they are not very familiar with the symptoms of osteosarcoma, they ignore medical treatment even if the disease occurs, which delays the best time for recovery. In order to let more friends understand what osteosarcoma is, let us learn about the symptoms of osteosarcoma together.

The prominent symptom of osteosarcoma is pain at the tumor site, which is caused by the tumor tissue eroding and dissolving the bone cortex. Common symptoms 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. The lump may be palpated 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) Lameness: Pain-avoiding claudication caused by limb pain worsens as the disease progresses. Long-term patients 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 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.

Patients need to be reminded that the pain of osteosarcoma will not decrease after rest, but will gradually increase. If it is just an injury, the pain may at least decrease after two or three weeks. But the pain of osteosarcoma will become more and more severe. The symptoms of osteosarcoma have two basic characteristics, the first is pain, and the second is night pain. The pain of osteosarcoma is progressive. It may be bearable in the early stage, but it will become more and more severe later. Once the above symptoms appear, you need to see a doctor as soon as possible for diagnosis and treatment.
