What are the signs of early stage lung cancer?

A persistent cough

A cough can be a sign that your body is suffering from a cold or a respiratory infection. Usually, this phenomenon can disappear after 1-2 weeks. However, if the cough lasts for a long time and does not go away, it is highly likely that you have lung cancer. To know exactly what problem you are having, be alert and have your lungs checked as soon as possible by taking an X-ray combined with other necessary tests to determine the cause of the cough.

Chest pain

Among the 9 signs of early stage lung cancer, it is impossible not to pay attention to the symptom of chest pain, in addition, the patient may also have pain in the back or shoulder. The pain can be continuous, dull or occasional. Regardless of the nature, you should pay attention.

What you need to observe and monitor at this time is whether the chest pain only occurs in one area or spreads throughout the entire chest cavity. When the chest pain is caused by lung cancer, it will lead to an unpleasant reaction in the lymph nodes. They can metastasize to the chest wall, ribs or pleura.

Hoarseness does not heal on its own

Lung cancer has the ability to change the patient's voice. This is very easy to notice and the patient's voice may become deeper or hoarse than before.

Sometimes hoarseness is also a sign of a common cold but will gradually disappear after a short time. If you have hoarseness lasting more than 2 weeks, this is a warning of an unusual event that is quietly happening in your body.

In the case of a patient with lung cancer, the cause of the disease affecting the quality of the voice is due to a malignant tumor pressing on the nerve that controls the larynx or trachea, changing the patient's voice.

Cough changes

If you have a chronic cough, pay special attention to changes in these coughs, especially in people who have a habit of smoking. If you often have coughs, each cough lasts longer or the sound is hoarse, coughs up a lot of mucus or even coughs up blood, this is very likely one of the warning signs of lung cancer.

Lung cancer is a malignant disease and the leading cause of death. The best way to prevent lung cancer is not to smoke, because smokers have a much higher risk of developing lung cancer (about 20 times) than non-smokers. If you still smoke, quit smoking because it can affect your health.
