Lung Cancer: Symptoms

Lung cancer often doesn't cause symptoms in its early stages. This is when it's small and hasn't spread. Many lung cancers don't cause symptoms until they've already spread.

When lung cancer does cause symptoms, they're often like those you might have anyway if you smoke. For example, some early symptoms of lung cancer include shortness of breath and coughing.

These are some of the more common symptoms of lung cancer:

• Cough that doesn't go away or gets worse over time
• Chest pain, which might be worse when coughing or breathing in deeply
• Coughing up blood or rust-colored mucus
• Shortness of breath
• Hoarseness
• Wheezing
• Appetite loss
• Unexpected weight loss
• Feeling tired or weak
• Pneumonia or bronchitis occurring more than normal for you

Some symptoms can be caused by lung cancer spreading to other parts of the body:

• Trouble breathing that's getting worse
• Bone pain
• Belly or back pain
• Yellowing of skin and eyes (jaundice)
• Headache, seizures, or confusion
• Weakness or numbness in an arm or leg
• Enlarged lymph nodes in the neck
• Drooping eyelid
• Problems talking

Many of these symptoms can be caused by other health problems. It's important to see your doctor for an accurate diagnosis if you have these symptoms. Only a doctor can tell if you have lung cancer.
