When patients with advanced liver cancer have chest tightness, it is necessary to pay attention to the compression effect caused by liver cancer tumor itself, which will lead to chest tightness, and whether there is lung metastasis of liver cancer, and patients with combined heart disease and lung disease will also cause chest tightness. For patients with advanced liver cancer, the tumor itself is very large in size, which will exert pressure on the surrounding tissues and organs and cause chest tightness, so abdominal CT examination should be carried out to roughly understand the size of liver cancer. Patients with advanced liver cancer are prone to distant metastasis, such as metastasis to lungs, which will also cause chest tightness. If the patient’s heart and lungs have problems, it will also lead to chest tightness, which can be clarified by chest CT, heart ultrasound or electrocardiogram. If the patient is not feeling well, he should go to the hospital in time for examination and should not be careless so as not to delay the treatment.
