What symptoms should you pay attention to in preventing lung cancer? If you have the five major symptoms, be careful of lung cancer

Lung cancer is a malignant tumor that occurs in the lungs. It has a high mortality rate and morbidity rate, which can pose a great threat to the patient's life. When these five signs appear in the body, you should be careful about lung cancer and go to the hospital for examination as soon as possible.

The main cause of lung cancer is smoking. Studies have shown that long-term heavy smokers are ten to twenty times more likely to develop lung cancer than non-smokers. The younger you start smoking, the higher your chance of developing lung cancer. There are also air pollution, genetics, occupation, known lung diseases, etc. So what are the five major signs in your body that you should be careful of lung cancer?

The first of the five suspected lung cancer signals is coughing. This is mainly because the tumor grows on the bronchi and stimulates the bronchi, which causes coughing. The degree of this cough varies. Many patients have irritating coughs, with no sputum, a little white foamy sputum, or blood in the sputum. After secondary infection, they will cough up yellow sputum. If you have a chronic cough, you will find that the nature of the cough is different from usual, so you must be vigilant.

The second biggest signal is coughing up blood. Relatively few patients will experience this symptom. If it is central lung cancer, coughing up blood will occur in the early and middle stages of the disease. The amount of blood is not much, and it is bright red or mixed with foam. The reason for this phenomenon is that the surface of the tumor is rich in blood vessels, and coughing damages the surface, causing blood vessels to rupture. If there are patients who occasionally cough up a lot of blood, the condition will recur or last for a long time.

The third signal is fever. When central lung cancer grows in the bronchus and develops to the point where the lumen is semi-obstructed or completely obstructed, obstructive pneumonia will occur. The fever is generally around 38 degrees. It is easy to reduce the fever after anti-inflammatory treatment. However, if the obstructive lesions have not been removed, pneumonia will reappear soon, forming recurrent pneumonia.

The fourth signal is hoarseness. This symptom will appear at different stages, including in the early stages. The incidence rate of central lung cancer can be as high as 40%. The pathology of hoarseness caused by lung cancer is that the tumor invades and compresses the nerves that control the vocal cords. Generally, this hoarseness often occurs suddenly, progresses rapidly, and may even cause the patient to completely lose his voice. At the same time, most patients will also have chest pain, etc., and there will be no effect after rest and anti-inflammatory symptomatic treatment for more than two weeks.

The fourth signal is asymptomatic. One-third of lung cancer patients do not have any obvious early symptoms and can only rely on regular examinations to detect lesions early.

If these five signs appear, you should be careful about lung cancer. Therefore, people who smoke for a long time should pay more attention to changes in their bodies and check promptly if there are any abnormalities to avoid more serious consequences. In addition, people should quit smoking and drinking in normal times to reduce the incidence of lung cancer. Patients who already have lung cancer should receive treatment as soon as possible. The earlier the lung cancer is, the greater the chance of cure.
