Pay attention to these 7 inconspicuous symptoms of bone cancer!

Let's take a look at what causes bone cancer.

1. Chemical substances

Many animal experiments have shown that certain chemicals (such as methylcholanthrene) can induce osteosarcoma, which is also one of the causes of bone cancer.

2. Physical factors

Long-term exposure to ionizing radiation, such as X-rays, radium, hydrogen, strontium, etc., can cause bone cancer.

3. Benign bone diseases

Diseases of bone tissue such as enchondroma, osteochondroma, and osteoblastoma are also causes of bone cancer.

4. Genetic factors

Certain chromosomal abnormalities and a few rare genetic disorders are associated with bone cancer.

Early symptoms of bone cancer

1. Bone and joint pain or swelling, often worse at night and not necessarily related to activity; the pain may be constant, dull, or only felt when pressure is applied.

2. Bone cancer patients may suffer from pathological fractures or deformations in the early stages.

3. Fever, weight loss, fatigue, and decreased mobility sometimes occur in advanced bone cancer, while benign bone cancer usually does not cause pain.

4. You have persistent and unexplained back pain. You may just have a back disease or back pain.

5. One or more fractures with no obvious cause. After the fracture is treated, check for osteosarcoma or osteoporosis.

6. There will be numbness in the distal parts of the limbs due to compression of nerves and blood vessels.

7. A hard lump appears on the surface of the bone, with or without pain.

8. The pain of bone cancer is usually more severe at night than during the day.
