1. Difficulty breathing

Shortness of breath or wheezing may not be a serious symptom. However, if you suddenly have difficulty breathing after running up stairs when you have not had it before, you should talk to your doctor soon because these symptoms are likely caused by a tumor in the lung, obstructing your breathing.

2. Frequent coughing

A persistent cough that leads to hoarseness, a hoarse voice that lasts for several weeks without going away... can be caused by a lung problem, such as pneumonia, a lung infection. However, many people think that this symptom is caused by a cold or allergies and do not go for a check-up. As a result, the inflammation in the lungs gets worse, leading to lung cancer if not treated promptly.

3. Rapid weight loss without a clear cause

In any case, rapid weight loss without a clear cause, not related to your calorie reduction or exercise... is most likely caused by illness, including cancer. In addition, if you feel a loss of appetite, it is easier to conclude that the cause may be a tumor inside your body, not excluding a tumor in the lung that leads to lung cancer later. This tumor will suddenly increase your body's metabolism and cause the above condition.

4. Chest pain

A typical symptom of lung cancer is chest pain, especially when you feel pain deep in the lungs every time you lift something, when you cough or laugh. In addition, persistent pain in the chest that does not go away after a long time can also be a sign of lung cancer that you need to pay attention to.

5. Pain in the hands and fingers

Pain and fatigue in the fingers can be two early warning signs of lung cancer that many people tend to ignore. In most cases, when the skin of the palms becomes thick and white with obvious wrinkles, the more likely you are to have lung cancer. You should see a doctor to determine your condition.

6. Blood in the sputum

Coughing up blood in the sputum is never a good sign, even if the amount of blood is very small or light in color. If you experience this condition, you should see a doctor immediately because it can be an early warning sign of lung cancer or some serious disease in your body.

7. Mood swings

If you feel like you can easily change your mood quickly, get angry and irritable, followed by fatigue and even depression... then you are at risk of lung cancer or some other cancer. Because cancer can cause hormonal imbalances, it can irritate the nerves that control emotions.

8. Frequent infections

Lung cancer can cause infections that affect the respiratory tract and lead to diseases such as bronchitis or other chronic infections. If you have chronic lung infections, you should take the time to get a chest X-ray to see if you are at risk of lung cancer.

9. Shoulder pain

Shoulder pain can occur if a lung tumor grows and puts pressure on the upper part of the lung and the nerves in the armpit. This pressure often leads to pain, tingling, and aching in the shoulder, inside the arm, and hand.

10. Abnormal breast tissue

This sign is more common in men. It is a condition in which the chest area becomes abnormally enlarged due to cancer cells stimulating the secretion of hormones in an abnormal way. However, women should not ignore this because it is very likely caused by lung cancer cells or cancer in other organs.
