Lung nodules in women are usually found through lung CT examinations, manifesting as focal, round-like shadows, which can be single or multiple, the cause is not very clear, and may be related to the following common factors: 1. Environmental impact: long-term exposure to environments containing large amounts of vinyl chloride, asbestos and other harmful substances, the body will inhale large amounts of these substances, which in turn leads to a decline in lung function, triggering inflammation and immune response in the lungs, resulting in the formation of Lung nodules. Usually should do a good job of protection, wear a good mask and other protective equipment, to minimize the inhalation of harmful substances; 2, organism infection: if usually do not pay attention to hygiene, their own body immunity is also relatively weak, it is easy to lung infection, such as bacterial infection, viral infection, mycobacterial infection, etc., lung CT examination may find nodules; 3, genetic: lung nodules may be vascular malformations, benign tumors or malignant tumors, especially female lung adenocarcinoma, often with pulmonary ground glass nodules as the first manifestation, these neoplastic diseases may be caused by multiple factors such as genetics and radiation, such patients can be treated by surgery according to the situation, with radiotherapy if necessary.
