At the outset of lung cancer, there are no specific symptoms or signs. 40% of lung cancer patients are identified in the advanced third stage of the illness.

Even early chest x-rays fail to reveal this condition. In contrast, CT scans are much more accurate in detecting cancer. People between the ages of 55 – 80, and those who have been smoking for more than 15 years, are particularly at risk.

Everyone wishing to avoid or prepare for lung cancer should be aware of seven early warning signs.


If you’re breathing properly and hearing whistling or wheezing, you should visit a doctor immediately. A wide variety of medical disorders might cause this, ranging from benign to treatable, such as a blocked or irritated airway, to cancer of the lungs.


This may be a sign of lung cancer, caused by obstruction or constriction of airways, or through fluid collection in the chest as a result of a tumor in the lungs. If you’re having trouble accomplishing simple things that you’ve never had a problem with in the past, it’s a sign that you should see a doctor right once.


The chest, back, or shoulders may develop pain

As a consequence of aggravation or metastasis of the ribs, and lymph nodes, chest pain should not be overlooked. Irrespective of how well you feel, it is enough to prompt you to seek medical attention.

Coughing that won’t go away

Coughing that persists for an extended time is a warning indication that you may have lung cancer. If it lasts more than two weeks, it’s most likely simply a cold or another respiratory illness causing the cough. You should, however, contact a doctor immediately if you start coughing up mucus, and they should thoroughly examine your chest and lungs, including x-rays. Coughing up blood or additional mucus or coughing more often with a rougher, deeper sound are all possible changes to the cough. People who experience these signs and symptoms should seek medical attention as soon as possible.

Constant headaches

Constant headaches may be a symptom of lung cancer that has spread to the brain. Not all headaches, however, are caused by brain metastases. When a tumor grows on a major vein that carries blood from the heart’s upper chambers, it might exert pressure.

Inflammation of the Bones

If you notice increased pain in your bones or other parts of your body, it may indicate that you have a health problem and should consult a doctor.
