10 Common Cancers and Their Warning Signs

Lung cancer

Estimated new U.S. cases in 2018: 234,030

Signs of lung cancer include:

• A persistent cough that doesn’t go away and gets worse over time
• Coughing up blood
• Wheezing or shortness of breath
• Constant chest pain
• Bone pain
• Hoarseness or other voice changes
• Regular lung infections (like pneumonia or bronchitis)
• Losing weight without trying
• Not feeling hungry
• Frequent headaches
• Blood clots

Lung cancer doesn’t usually cause symptoms until it’s advanced (also referred to as late-stage cancer). That’s because your lungs have few nerve endings, so tumors can grow there without causing pain. If you have any of the signs above, see your doctor to get tested for lung cancer and other possible causes, such as asthma.
