Pleural invasion is generally a more serious condition, because pleural invasion generally indicates that the cancer lesion is in the middle or late stage, the cure rate of the patient is low, and the survival time of the patient is shortened. In general, after pleural invasion of cancer lesions, many patients will have complications such as cancerous pleural effusion, which will easily cause obvious clinical symptoms such as chest tightness, breathlessness, and inability to lie down, and many patients will have serious chest pain, and they will not be able to sleep or eat normally, which will lead to a significant decrease in the quality of life. At the same time, pleural invasion indicates a wide spread of the lesion, which reduces the clinical cure rate and shortens the survival period of patients. It is recommended that patients with pleural invasion should consult the doctor in time, complete the corresponding examinations according to the needs of the disease, and cooperate with the doctor to actively treat the disease, reduce the symptoms and prolong the survival period.
