Back pain, early symptoms of lung cancer

Back pain Early symptoms of lung cancer:

Generally speaking, before judging whether back pain is an early symptom of lung cancer, we should first determine whether it is caused by lung cancer, because some diseases, including coronary heart disease, some muscle and bone injuries or diseases of the back, can also cause back pain.

If these conditions are excluded and lung cancer is confirmed to be the cause, there may be two situations:

One is the local progression of lung cancer lesions, invading the posterior chest wall.

The second is tumor metastasis, affecting the bones, muscles and other tissues in the back. Neither of these two situations is the early stage of lung cancer.

Lung cancer has no special symptoms in the early stages, but only common symptoms of general respiratory diseases, such as cough, blood in sputum, low fever, chest pain, shortness of breath, etc., which are easily overlooked.

Specific manifestations of common early symptoms of lung cancer:

1. Cough. Lung cancer grows on bronchial lung tissue, usually causing respiratory irritation symptoms and irritating cough.

2. Low fever. When the tumor blocks the bronchus, there is often obstruction of the lung lobe to varying degrees. Mild cases only have low fever, and severe cases only have high fever. It can temporarily improve after taking medicine, but it will relapse soon.

3. Chest pain. In the early stages of lung cancer, chest pain is mild and is mainly manifested as dull pain, dull pain, and the location is uncertain, and the relationship with breathing is also uncertain. If swelling and pain continue to occur, it means that the cancer may involve the pleura.

4. Sputum and blood. Tumor inflammation leads to necrosis, and capillary damage will cause a small amount of bleeding, which is usually mixed with sputum and appears intermittently or intermittently.
