Understanding the diseases that resemble lung cancer

Lung cancer is a serious disease that can be fatal for Illinois victims if not treated properly. However, it’s important to understand that there are several other diseases that have symptoms that are similar to it.


This is a lung infection that causes the airways to become inflamed, which can lead to a cough, shortness of breath and chest pain. One of the key distinguishing symptoms of bronchitis as opposed to lung cancer is that bronchitis usually goes away on its own after a few weeks, while lung cancer symptoms persist and worsen over time.


Pneumonia is another lung infection that can cause similar symptoms to lung cancer, including a cough, chest pain and difficulty breathing. An example of a misdiagnosis is when pneumonia is mistaken for cancer because both conditions can cause an abnormal chest x-ray. However, pneumonia is usually accompanied by a fever, which doctors don’t normally see among lung cancer patients.

Congestive heart failure

This condition occurs when the heart can’t pump enough blood to meet the body’s needs, which can cause fluid to build up in the lungs and lead to shortness of breath, chest pain and fatigue. However, unlike lung cancer, congestive heart failure is often accompanied by other symptoms such as swelling in the legs, ankles and feet.


Asthma is a chronic lung condition that causes the airways to become inflamed and narrow, which can lead to symptoms such as shortness of breath, wheezing and chest tightness. However, asthma attacks are usually triggered by environmental factors such as dust, pollen or smoke, which is not typically seen in lung cancer patients.

Pulmonary embolism

This is a serious condition that occurs when a blood clot blocks one of the arteries in the lungs, which can cause shortness of breath, chest pain and an irregular heartbeat. A pulmonary embolism is usually accompanied by other symptoms such as leg pain or swelling, which you’ll rarely see among lung cancer patients.

If you or someone you love is experiencing any of these symptoms, it’s important to see a doctor right away for a proper diagnosis. Early detection is key to surviving lung cancer, so don’t delay in getting the help you need.
