What are the symptoms of lung cancer? 4 symptoms of lung cancer that should not be ignored

Most lung cancers are caused by chronic lung diseases. As air pollution worsens, lung cancer has become the most common cancer. Experts say that this is mainly because patients do not pay enough attention to the early symptoms of lung cancer, which makes the disease easily worse and spread. Many of the lung cancer symptoms that cannot be ignored are relatively common.

1. Cough. Bronchial lesions are the most common condition of lung cancer, and they are also the most neglected symptom of lung cancer that cannot be ignored. Tumors compress and irritate the respiratory tract, causing irritating coughs. Usually, the initial symptoms are intermittent coughs without sputum, and once infected, they will manifest as coughs with sputum.

2. Blood in sputum. Tumor cells can damage lung tissue, causing damage to capillaries. Once capillaries rupture and bleed, patients are prone to this symptom. This symptom is also intermittent, and many patients only begin to notice the disease because of blood in their sputum.

3. Fever. Tumors can easily cause fever. Generally, patients with milder conditions have a low fever, while those with more serious conditions have a high fever that does not subside, and are prone to recurring symptoms.

4. Breathlessness. Tumors can affect the patient's lung function, especially when the patient is overworked, the symptoms of breathlessness are more prominent. Some patients may also experience chest pain, which can develop into persistent pain in severe cases.

These symptoms are all symptoms of lung cancer that cannot be ignored. If ignored, it can easily lead to the disease growing secretly, and even become difficult to control in the end, putting the patient on the verge of death.
