What are the early symptoms of lung cancer? If you have these three signs, be alert

Many people do not know that lung cancer has become one of the top three cancer diseases in terms of mortality. The most common cause of the disease is smoking. Whether it is first-hand smoke or second-hand smoke, it will cause damage to the lungs. The early symptoms of lung cancer are not very obvious and can easily be mistaken for a cold, thus delaying the best time for treatment. Let's take a look at the early symptoms of lung cancer .

Early symptoms of lung cancer

1. Pain in the chest, shoulders, and back. Early cancer cells grow at the apex of the lungs and are particularly prone to invading nerves, muscles, bone joints, chest wall, and pleural membranes. At this time, persistent or intermittent pain will occur. In other words, if local pain in the chest, shoulders, back, etc. suddenly occurs, you should pay attention. At the same time, early lung cancer cells will also compress the brachial plexus nerves, causing soreness in the arm on the same side. At this time, the arm will not be able to be lifted, and the fingers will have radiating pain.

2. Fever. One of the more obvious characteristics of early lung cancer is fever, and it is a high fever, the temperature is often above 39 degrees, the temperature fluctuates by about 1 degree in 24 hours, and the lowest body temperature is also higher than the normal body temperature.

3. Chest tightness. Early-stage lung cancer patients often feel chest tightness. If cancer cells have invaded the pleura or chest wall, it will also cause chest pain. What everyone needs to pay attention to is that if a respiratory disease has not been cured after more than 2-3 weeks of treatment, or if the symptoms worsen after treatment, you should be alert and go to the hospital immediately for lung cancer screening.
