The fact that the lung nodule grows again after the surgery only indicates that the patient has a hyperplastic body. It is recommended to have another surgery to remove the nodule. After the surgery, we should maintain a relaxed mood, emotional stability, eat more nutritious and easy to digest food and fresh vegetables and fruits, pay attention to not eat spicy, stimulating and greasy food, do not stay up late, to ensure sufficient sleep. Pay attention to hygiene after surgery to prevent infectious inflammation, which will affect wound healing. You can apply hot compresses and take anti-inflammatory drugs orally. During the recovery period, supplement nutrition on time to promote wound healing, and prevent the consumption of spicy and stimulating foods. However, if the nodules show lobulated, short burr-like, pleural traction sign, pleural depression sign, and show growth changes, then we need to be highly alert to the possibility of early lung cancer. Enhanced CT examination of the chest, thoracic nodule puncture and cytology and histology examination are feasible when necessary to determine whether it is early lung cancer.
