Many patients suffer from decreased lung function due to long-term smoking and inhalation of excessive dust, which causes tumors to enter the body and cause lung cancer. Long-term smoking has a great relationship with the occurrence of lung cancer. The younger the person is, the longer they have smoked, and the greater the chance of developing lung cancer. This type of disease will infiltrate the lung tissue, causing damage to lung function and affecting lung health.

When the tumor invades the lungs and the pleura, it will cause obvious pain in the pleura.
