10 Early Warning Signs of Lung Cancer

Lung cancer is mainly a result of smoking. However it can develop in a non-smokers lungs as well. This article discusses some of the main symptoms that should not be ignored. If you or a loved one is having any health issues please do seek help from a medical professional.


What is lung cancer and how does it start or occur in the body? Cancer of any type begins with abnormal cells. All of us have cancer cells in our body. Lung cancer is one form of abnormal cell growth that gets out of control.

A lung cancer diagnosis is frightening, but early diagnosis can improve survival rates by nearly half, according to the American Cancer Society. Although many of the early warning signs for lung cancer can be caused by something else, being aware can help you know when to visit the doctor. Keep reading for ten signs if ignored could raise your risk or early lung cancer detection.

“early warning signs you
should know”

A recurring or worsening cough

If you suddenly develop a cough that never seems to go away, even after a couple of weeks, it may be time to visit your doctor. And while a persistent cough might worry you, it might be worse if you see any blood.

Bloody cough

If coughing causes you to cough up mucus or other matter from your lungs, always check for blood. Even a little blood can be an early sign of lung cancer, and you should also be aware of pain during coughing.

Chest pain

A cold or infection can cause chest pain when coughing, but pain throughout the chest area that persists even when there is no cough is a cause for concern. Some people also experience pain in their back, shoulders or arms. Although it might seem like a minor concern, chest pain, like a hoarse voice, can be a sign of something worse.


A hoarse voice is another symptom that can be caused by a simple cold, but consult with your doctor if it lasts longer than the cold, or about two weeks. Lung cancer can affect the voice box, which causes the voice to sound deeper or raspier. A hoarse voice can also be accompanied by wheezing.


Wheezing is often caused by something less serious than lung cancer, such as allergies, asthma or a cold. If treatment for other causes doesn’t improve your condition, it could be a sign that the lungs are inflamed or constricted by lung cancer. Inflamed lungs can also cause shortness of breath.

Shortness of breath

Don’t ignore it if you feel winded when doing things that never caused problems for you before. Lung cancer can block airways, making breathing more difficult after even light activity. Feeling short of breath after activity and feeling tired often go together, and tiredness can be another symptom of lung cancer.

“don’t ignore your symptoms”

Many people ignore some of the symptoms simply because they are unaware of the relation between how they feel and the possibility of cancer developing. Cancer – any type of this disease, is scary. But ignorance does not mean the problem will go away.

If you’re like me, or most people, you may want to avoid going to the doctor. With symptoms like these it’s not a good thing to ignore finding out what is happening. Better safe than sorry.

Weakness or tiredness

Cancer can make people feel weak and tired. A sense of fatigue that doesn’t get better with rest is a signal to see a doctor. Lung cancer can also cause weakness in the fingers. Feeling weak could also be caused by a loss of appetite, and that is another symptom.

Loss of appetite and weight

Unless you are dieting, a sudden loss of more than ten pounds could be a sign of cancer. A sudden loss of appetite can also be a sign of declining health. If you experience weight loss with no explanation, you should consult with a doctor to find the cause. Losing weight can make you more susceptible to infections, which can worsen when lung cancer is present.

“CONSISTENT Pulmonary conditions”

Recurring pulmonary (lung) infections

Lung cancer can weaken the lungs, making infections such as pneumonia and bronchitis more difficult to fight. If either of these conditions returns after treatment, it could be a sign of something more serious. Serious, recurring infections can weaken lungs to the point where they collapse, which is called pneumothorax.


A pneumothorax is a collapsed lung that causes difficulty breathing and sudden pain in the chest. While the condition can be caused by a chest injury, it can also happen when lung disease damages the lung.

While some of these symptoms may be caused by a simple infection or other minor cause, be sure to visit your doctor early if you are concerned. An early diagnosis for lung cancer makes a good outcome much more likely.

“bad habits or bad environment”

Lungs of SmokersFor the most part when we think about lung cancer we look to cigarettes and perhaps asbestos as the cause of this disease. According to the CDC (Center for Disease Control) anywhere between 80 to 90 percent of all lung cancers are related to smoking.

In most cases it is the smoker who suffers. However, about 7,330+ people develop lung cancer from breathing second hand smoke.
