What are the early symptoms of lung cancer? Several early symptoms of lung cancer

Lung cancer is a very harmful malignant tumor that has a great impact on the patient's body and mind, and needs everyone's attention. In recent years, the incidence and mortality of lung cancer have been on the rise, and a big reason for this is related to environmental pollution, especially in some industrial countries, where air pollution is serious and the number of people suffering from lung cancer is generally high. So what are the early symptoms of lung cancer? Let's learn about them together, which will help to detect the disease in time.

Hoarseness is one of the most important early symptoms of lung cancer, and it is also a new discovery that experts at home and abroad have been exploring in recent years. Hoarseness can occur in pharyngitis, colds, and acute bronchitis; after thyroid surgery, pharyngeal surgery; it can also occur after improper voice production, excessive speech, or even after heavy smoking and drinking. However, this type of hoarseness can generally be treated symptomatically or healed by rest. The hoarseness caused by lung cancer, thyroid cancer, and laryngeal cancer is completely different from the above hoarseness, especially lung cancer.

What are the early symptoms of lung cancer? Other early symptoms of lung pain, such as cough, chest pain, hemoptysis, etc., lack characteristic features, but hoarseness has certain specificity. According to statistics, about 20% to 30% of lung cancer patients may experience hoarseness at different stages of the disease, including the early stage, of which central lung cancer may be as high as 40%. The pathology of hoarseness caused by lung cancer is that the tumor invades and compresses the nerves that control the vocal cords. This hoarseness often occurs suddenly, progresses rapidly, and even completely loses the voice. At the same time, most patients are accompanied by chest pain, etc., and rest and anti-inflammatory symptomatic treatment for more than two weeks are still ineffective.
