It is best to discuss your risk and any symptoms with your doctor

When a cough doesn't go away or changes

Coughing that remains constant can be a sign of lung cancer. Coughing that is associated with a viral infection or cold will subside in a few days, but prolonged coughing can be a sign of lung cancer. Having difficulty breathing can also be a sign of lung cancer. If the body's airways are blocked by tumors or fluid builds up in the chest, breathing becomes difficult.

Bring it to your doctor’s attention

A wheezing or whistling sound is a sign of constrictions, obstructions, or inflammation of the airways in your lungs. Several causes can cause this, some of which are benign and easily treatable. When you cough or throughout the day, you may experience chest, shoulder, or back pain caused by lung cancer.

Add Block

This may also make your lungs weak

There is some evidence that headaches are associated with lung cancer metastasizing to the brain, though not all headaches are caused by lung cancer metastasizing to the brain.

The voice is raspy and hoarse

You should see your doctor if you notice that your voice has changed significantly or if you or another person notices it sounds deep or hoarse.

Weight loss that cannot be explained

Lung cancer may cause unexplained weight loss of 10 pounds or more. Cancer cells may use energy to drop in weight. Your body might also use energy differently when you're ill.
