Subpleural nodules are generally more benign and less malignant.
In terms of clinical morbidity, most subpleural nodules are benign and may be the result of previous lung infections, such as pleurisy, tuberculosis, pneumoconiosis, etc., and old foci that develop as the infection heals, or small foci of infection that are currently present.
A small percentage of subpleural nodules are malignant, such as pleural tumors and pleural mesothelioma, and require aggressive treatment.
When subpleural nodules are found, relevant examinations should be further improved, such as tumor marker examination, chest enhancement CT, puncture biopsy and other examinations, in order to clarify the cause of the disease, and actively cooperate with the doctor to carry out treatment if necessary, so as not to delay the condition.
