According to the CDC, every year more people die of lung cancer in the United States than any other cancer. As with any type of cancer, early detection is a key factor when it comes to chances of survival. How can you stay your safest? Read on to learn about conditions that can feel like lung cancer—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.
Smoking, COPD, Emphysema

Smoking irritates the lungs and can lead to a chronic cough as well as lead to other medical problems that can mimic lung cancer symptoms. A chronic cough can cause aching muscles and chest pain. Smoking can also cause COPD, a serious lung disease that makes it difficult to breathe. People with COPD often experience a chronic cough. Emphysema is a form of COPD that is caused by damage to the air sacs in the lungs. It can lead to shortness of breath and coughing, particularly when breathing in. End-stage emphysema can also lead to unintentional weight loss.
Bronchitis

Bronchitis is an inflammation of the lining of the bronchi, the airways that carry air to and from the lungs. It is a common illness, affecting millions of people each year in the United States. Most cases of bronchitis are caused by a virus, and most people recover within a week or two without treatment. Bronchitis can cause all the early symptoms of lung cancer (cough, coughing up blood, chest pain, shortness of breath) and, if chronic, weight loss.
Pneumonia

Pneumonia is a lung infection that can be serious. It can cause difficulty breathing and chest pain. Pneumonia is most common in young children and older adults, but it can occur at any age. Cough is frequent. The other symptoms mimicking lung cancer can occur and if there are recurring bouts or chronic infection unintentional weight loss can result.
Tuberculosis

Tuberculosis is a serious lung infection – a type of infection – caused by a bacterium called Mycobacterium tuberculosis. A bloody persistent cough, fevers, and weight loss are all common symptoms.
Asthma

Asthma comes in two forms: cough variant and non-cough variant. In the majority of cases, asthma is a non-cough variant. It is a common lung disease that affects people of all ages, but it is most common in young people. Symptoms of asthma include wheezing, chest tightness, and shortness of breath. These symptoms can be caused by an allergic reaction. In cough variant asthma you have difficulty breathing, but do not have an asthma attack. The person will usually have a cough that is worse at night or early morning. The cough may be dry or may produce sputum.
Heart Failure

Heart failure can cause shortness of breath by causing the lungs to fill up with fluid. This occurs because the heart is not able to pump enough blood to meet the body's needs and fluid backs up. Symptoms of heart failure include shortness of breath, fatigue, and swelling in the feet and legs.
Blood Clots

Blood clots in the pulmonary arteries can cause extreme shortness of breath since the clot will block the flow of blood to the lungs. Blood clots can form in the veins of the leg (deep vein thrombosis) and travel to the arteries of the lung (pulmonary embolism). Symptoms of a blood clot in the lung include chest pain, shortness of breath, rapid breathing, and coughing up blood. It is a medical emergency.
Anemia

Anemia causes shortness of breath since it reduces the amount of oxygen that is carried in the blood. Anemia can be caused by a variety of problems, including iron deficiency, vitamin B12 deficiency, and sickle cell anemia. Symptoms of anemia include fatigue, shortness of breath, and pale skin.
Medications

Medications that cause shortness of breath include beta-blockers, which are used to treat high blood pressure and heart problems, and ACE inhibitors, which are used to treat heart failure and high blood pressure. Other medications that can cause shortness of breath include narcotic pain medications and antihistamines. ACE inhibitors can cause a cough in some people. Some medications can cause weight loss such as cancer treatments.
What to Do if You Experience Symptoms

If you have any of these symptoms it is important to see your doctor. Chances are that the symptoms may be due to a non-cancer cause. Early diagnosis and treatment are the best way to increase your chances of surviving lung cancer.
