What are the early symptoms of lung cancer? These are the common symptoms of lung cancer in the early stage

I don't know how much you know about lung cancer. Lung cancer is too common for all of us. There are many patients with lung cancer in our lives. Because at present, the incidence of lung cancer is still very high in our country. Since the incidence of lung cancer is so high, it is very important for us to understand its early symptoms to prevent the occurrence of lung cancer.

Cough: Lung cancer has different symptoms due to its different locations and functional damage. Since tumors mostly grow on large bronchi and are highly irritating, coughing is easy to occur. However, the degree of coughing varies. About 50% of patients have irritating coughs, no sputum or a little white foamy sputum.

Hoarseness: This is the most important early symptom of lung cancer and a new discovery that experts at home and abroad have been exploring in recent years. This type of hoarseness often occurs suddenly, progresses rapidly, and may even cause complete loss of voice. At the same time, most patients also have chest pain, etc., and rest and anti-inflammatory symptomatic treatment for more than two weeks are still ineffective.

Fever: When central lung cancer grows in the bronchus and develops to the point where the lumen is semi-obstructed or completely obstructed, obstructive pneumonia may occur. The fever is generally around 38°C and can be easily reduced with anti-inflammatory treatment. However, if the obstructive lesions are not removed, pneumonia will reappear soon, forming recurrent pneumonia.

Swelling and pain in bones and joints: Mainly affecting the tibia, fibula, ulna, radius and other bone joints of the legs. The tips of the fingers and toes are often swollen and clubbed. If there is no obvious effect after rheumatoid arthritis related treatment, it is necessary to promptly consider whether it is an early symptom of lung cancer.
