Clinical manifestations of lung cancer show symptoms such as cough, dyspnea, chest pain, chest tightness and infection, depending on the location of the tumor.
Lung cancer will cause the alveoli to be unable to work normally due to the tumor compressing the respiratory system, which makes the oxygen transportation not smooth and triggers irritating cough, dyspnea as well as chest tightness and other symptoms.
When the tumor stimulates the pleura, the patient will experience cutting or pins and needles pain, and the symptoms will be aggravated when he/she breathes, and the sputum cannot be coughed out in time due to the tumor compression, and the bacteria in the sputum will multiply in the lungs, which may lead to infections and other symptoms.
In addition to the above clinical manifestations, the patient may also be accompanied by skin symptoms, such as dermatomyositis, hyperkeratosis of the skin, etc. Therefore, the patient should consult the doctor in time after diagnosis, and should not be negligent in order to avoid delaying the treatment.
