What are the early symptoms of lung cancer? There are 3 symptoms of early lung cancer

When treating lung cancer, the sooner you start, the better. In the early stages of lung cancer, the cancer cells are still very small and not harmful enough to our bodies, so it is still very unlikely to be effectively cured. Once it develops to the late stages, it will be impossible to achieve good results. Here are some common complications after lung cancer surgery.

(1) Respiratory complications: such as sputum retention, atelectasis, pneumonia, respiratory insufficiency, etc. The incidence rate is higher in the elderly and weak, and those with chronic bronchitis and emphysema. Due to the pain of the wound after surgery, the patient cannot cough effectively, and sputum accumulation causes airway obstruction, atelectasis, and respiratory insufficiency.

(2) Postoperative hemothorax, empyema and bronchopleural fistula: Postoperative hemothorax is a serious complication that requires emergency treatment and, if necessary, a second thoracotomy should be performed to stop bleeding. During lung surgery, bronchial or pulmonary secretions may contaminate the chest cavity and cause empyema.

(3) Complications of the cardiovascular system: old age and frailty, traction and stimulation of the mediastinum and hilum during surgery, hypokalemia, hypoxia and massive bleeding are often the causes. Common cardiovascular complications include postoperative hypotension, arrhythmia, cardiac tamponade, heart failure, etc. Because surgical treatment is limited to surgical resection of tumors that can be found, and there is nothing to do for those hidden cancer cells that are still in the inactive stage, multicellular biological therapy combined with surgical treatment, radiotherapy and chemotherapy has become the best method for treating lung cancer.

These are all useful knowledge when we treat lung cancer. Some patients are not clear about the early symptoms of lung cancer, so they often cannot grasp the best time to treat lung cancer. In this case, the treatment often cannot achieve good results. I hope this is helpful to everyone.
