A 13mm lung nodule may be asymptomatic in its early stages, or it may present with symptoms such as cough and chest pain.
If the size of the lung nodule is 13mm and in the early stage, it may be asymptomatic, especially in benign nodules, which can be detected only during lung imaging, and it is normal to have no obvious symptoms in daily life and normal respiratory function.
However, some people may have symptoms in the early stage, including cough, sputum, hemoptysis, chest pain, etc. Because lung nodules grow in the trachea and bronchus, they can affect the normal respiratory function, and after affecting the normal airflow, they may cough, and malignant lung nodules can also lead to chest pain. Therefore, it is necessary to consult a doctor in time and carry out scientific treatment under the doctor’s guidance.
