Beware of the six signs of lung cancer: These people need to be especially careful about the invasion of lung cancer!

Lung cancer, a malignant tumor with a very high mortality rate worldwide, quietly invades our lives. It is not without signs. In fact, the body will send out some warning signals in certain situations, but they are often ignored. The following are the six major signs of lung cancer that certain people should pay special attention to.

Lung discomfort is a common sign of lung cancer for long-term smokers or passive smokers. A persistent cough, especially one with bloodshot eyes, may be a sign of lung inflammation, but it may also be an early sign of lung cancer.

Recurring pneumonia or tuberculosis, especially after treatment, may be a sign of lung cancer metastasis. Lung tumors can affect the local immune system, causing recurrent infections.

Hoarseness, especially if it persists for no apparent reason, may be a sign of compression of the recurrent laryngeal nerve by a tumor. This is especially common in women and older people who have never smoked.

Chest pain or shoulder or back pain, especially persistent, severe pain, may indicate that lung cancer has invaded the pleura or ribs.

Unexplained rapid weight loss without obvious changes in diet may be a result of the tumor consuming a large amount of energy.

If you cough up blood for no apparent reason, especially if you cough up bright red blood, you should seek medical attention immediately, as this may be a sign of early bleeding from lung cancer.

People who are exposed to harmful substances for a long time, such as asbestos, radioactive substances, or are occupationally exposed to carcinogens, as well as those with a family history of lung cancer, should be more vigilant, have regular lung examinations, and detect and treat the disease early.

Knowing these warning signs of lung cancer is crucial for early detection and treatment of lung cancer. If you or someone close to you has the above symptoms, be sure to seek medical attention immediately and do not ignore them. Prevention is always better than cure. Maintaining a healthy lifestyle and regular physical examinations are our first line of defense against lung cancer.
