Some obvious signs before the arrival of lung cancer are often easy to be ignored. The following signs are warning signals from your body that you may have lung cancer:
Signal 1: Hemoptysis
This is one of the most alarming of all the signs, when there is bloody sputum or sputum with other shapes of blood in it, go to the hospital immediately.
Signal 2: Dry cough
The dry cough here refers to irritating dry cough, which is mostly characterized by the absence of sputum or a small amount of white sticky sputum. People who need to pay special attention to this sign include long-term smokers over 40 years old, and when there is obvious irritating dry cough that lasts for more than two or three weeks, it is necessary to be alert to the fact that the cause of the cough is from lung cancer.
Signal 3: Chest tightness
Like dry cough, when lung cancer involves the wall layer of pleura or directly invades the chest wall, it can cause persistent pain in the area, resulting in chest tightness. When respiratory symptoms persist for more than two weeks without treatment, please go to the hospital to check whether lung cancer is possible.
Signal 4: Shortness of breath
Shortness of breath is one of the main symptoms of cancer patients. When shortness of breath symptoms appear and tend to worsen, be careful. Many people think that shortness of breath is a natural reaction to aggravation with age, but in fact, it may also be a hidden sign of other major diseases, so be sure to go to the hospital for examination.
Signal 5: Recurrent pneumonia or bronchitis
When a tumor is present in the lungs, it can block the airways and cause an infection, leading to pneumonia and bronchitis. Although the inflammation is caused by lung cancer, in some cases, the image of pneumonia on X-ray masks the lung cancer mass, making diagnosis difficult. When recurrent lung infections occur, it is important to ask your doctor for an in-depth examination of the cause of the infection.
Symptoms of lung cancer can be easily masked by other lung diseases. Please pay attention to the above “warning signals” from your body, and actively go to the hospital for early detection and early treatment.
