What are the precursors of lung cancer? Four major lung cancer symptoms that you should know clearly

When patients experience pain in one arm or are even unable to lift it in daily life, they should not assume that they have frozen shoulder. It is likely that there is a problem with the lungs. 10% of patients will develop lung cancer. When patients have lung cancer, the most common symptoms are pain, hoarseness, facial and neck edema, pleural effusion and other symptoms.

We all know that lung cancer is one of the malignant tumors with a relatively high incidence and mortality rate in my country. Not only in my country, but also in many countries, the mortality and incidence of lung cancer are relatively high. And it is showing an upward trend. The main cause of lung cancer is the decline in air quality. Lung cancer is also closely related to one's eating habits. When lung cancer occurs in the early stage, the symptoms are not very obvious, and I miss the best time for treatment, which can easily lead to misdiagnosis or missed diagnosis, resulting in delayed treatment. Next, we need to understand the early symptoms of lung cancer.

First of all, when patients develop lung cancer, the most common symptom is coughing. Almost all early-stage lung cancer patients will have coughing symptoms, and only a few patients will have blood in their sputum. Now many patients go to the hospital for treatment only after they have blood in their sputum. When patients have a cough for more than two weeks and it does not get better, they must go to the hospital for examination in time and be vigilant at all times.

If the patient experiences pain in one arm or is even unable to lift it in daily life, we must be vigilant at this time. It is likely that lung cancer has occurred in the early stages. Many patients who experience this symptom will think they have periarthritis of the shoulder and miss the best time for treatment. The tumor will invade the human nerves and cause pain in the upper arm.

Pain is a symptom often exhibited by patients with advanced lung cancer. Hoarseness is also one of the symptoms of advanced lung cancer. Often in the late stage, patients will also experience facial and neck edema, which requires timely correction and treatment at this time. It may also cause pneumothorax or pleural effusion.

When the patient feels pain, we can also relieve the pain through massage. We can apply cooling and analgesic drugs during massage. We can also use temperature stimulation or hot compress to relieve the pain. Each hot compress lasts about twenty minutes, which can have a certain analgesic effect.
