What are the earliest symptoms of lung cancer? The three most common symptoms of early lung cancer

Symptoms of early lung cancer are generally non-specific, or may present symptoms of general respiratory diseases, such as coughing, coughing up blood, etc. The most typical symptom is coughing, which is characterized by irritating dry coughs. At the same time, patients also have fever. Whether the fever is severe depends mainly on the severity of the patient's condition. The following is an introduction to the symptoms of lung cancer:

1. Lung cancer patients may have clubbing in the early stage, which is manifested by the enlargement of the first section of the fingers and toes, and the protrusion and bending of the nails. The early manifestations of lung cancer are often accompanied by pain. 21% of lung cancer patients will have this symptom, which usually disappears after surgery.

2. Lung cancer patients usually have progressive general weakness and loss of appetite. In severe cases, they may have difficulty walking and getting up from bed. This is called polymyositis periplasmic, and is also an early manifestation of lung cancer that is often ignored. Most lung cancer patients think that it is caused by other diseases, so they often use the wrong methods.

3. Most lung cancer patients will have bloody sputum, which is also an early manifestation of lung cancer and an early signal of lung cancer. Some lung cancer patients have repeated attacks of "pneumonia" and spit out bloody sputum, which comes and goes. Expert explanation: If there is no history of hemoptysis in the past, and unexplained bloody sputum appears, the first thing to think of is lung cancer.

The symptoms of advanced lung cancer are not single. Depending on the patient's physical fitness, the symptoms will vary to a certain extent, but they are generally very obvious. Lung cancer is a very harmful disease and also the disease with the highest incidence among malignant tumors. Middle-aged and elderly people should have sufficient awareness of prevention.
