These Symptoms Can Be Caused by Several Health Conditions, in Addition to Lung Cancer
It's normal to worry when your body doesn't feel quite right, especially if you find yourself short of breath or have a cough that won't go away. These symptoms can make you wonder whether lung cancer or another serious lung condition is to blame, and that's an understandable concern.
What makes things a bit complicated is that many of the symptoms linked to lung cancer are also common to other health conditions. A stubborn cough, chest pain or fatigue may be a sign of something serious, but it could also be caused by an infection, asthma or even acid reflux. Knowing the difference isn't easy, which is why it's important to pay attention to your symptoms and talk with a doctor if they don't go away.
Symptoms that may be a sign of lung cancer
Lung cancer can be sneaky because most people don't usually have obvious symptoms early on. When symptoms do appear, they may include:
- A cough that lingers or worsens over time
- Coughing up blood or rust-colored spit
- Chest pain that gets worse with deep breaths, coughing or laughing
- Hoarseness or changes in your voice
- Wheezing or shortness of breath
- Losing weight or appetite without trying
- Feeling unusually weak or tired
These symptoms don't always mean you have lung cancer, but they're a sign that something is going on that may need medical attention.
Other conditions that can cause similar symptoms
Just because you have one or more of these symptoms doesn't mean you have cancer. In fact, many other health problems share the same warning signs, including:
- Infections like pneumonia or bronchitis – These can cause cough, fever, chest discomfort and tiredness.
- Asthma or chronic obstructive pulmonary disease (COPD) – Both can lead to wheezing, frequent coughing and shortness of breath.
- Acid reflux (GERD) – Stomach acid can irritate your throat and lungs, leaving you with a chronic cough or hoarse voice.
- Allergies – Seasonal or environmental triggers can lead to coughing, wheezing and congestion.
- Smoking-related lung damage – Even without cancer, smoking can cause a chronic cough and breathing problems.
What to do if you notice these symptoms
If you've had a cough for more than a few weeks, or if you notice chest pain or tightness, hoarseness or unexplained weight loss, it's best to make an appointment with your healthcare provider. Even if it turns out to be something less serious, you'll have peace of mind and can start treatment if needed, so you start feeling better sooner.
Who should get screened for lung cancer?
If you smoke or recently quit and meet the following criteria, the U.S. Preventive Services Task Force recommends that you get a yearly low-dose CT scan to screen for lung cancer:
- Are between 50 and 80 years old
- Have smoked the equivalent of 20 pack-years (a pack a day for 20 years or two packs a day for 10 years)
- Currently smoke or quit within the last 15 years
Screening gives you a chance to catch lung cancer early, before symptoms even appear, when treatment often works best.
