There is no such thing as “5 early signs of lung nodules” in clinical practice, and there is no obvious gender difference in the symptoms of lung nodules. If the lung nodule is small, there are usually no obvious symptoms, and the situation varies from person to person. Some people with lung nodules may experience symptoms such as coughing, phlegm and chest tightness. In the case of very small lung nodules, people are usually asymptomatic, and most of them are detected through examinations, mainly due to the lack of sensory nerves in the lungs. If the location of the nodule is in the vicinity of the airway, the patient will show coughing, which may be irritating choking, shortness of breath, or obstructive inflammation due to the collection of secretions from the obstructed airway. As the lung nodule grows and involves the chest wall or pleura, other symptoms such as chest pain and chest tightness may occur. When the above symptoms occur, it is necessary to go to the hospital in time to confirm the diagnosis through the lung CT and other targeted examinations, and under the guidance of the doctor to carry out treatment or regular review.
