Lung cancer is something nobody ever wants to be diagnosed with and while it can be scary to deal with, if caught in the early stages, it is treatable. The best way to catch lung cancer early is to know what symptoms to watch for.

Many of the most common symptoms of lung cancer are similar to other diseases and illnesses, so it is important to see a doctor if you are experiencing any of them.

Cough
A cough can be a symptom of a lot of things, from a common cold to something more serious. If the cough does not go away after a few days, you should see a doctor immediately and request an X-ray of your chest and lungs. Because coughs are so common, many people dismiss them, but a constant cough can actually be one of the first symptoms of lung cancer.

Back And Chest Pain
Before you notice a cough or any other symptom of lung cancer, you might notice pain in your neck, back or even arm. If the pain does not go away and your doctors cannot find another reason for it, it could be a symptom of lung cancer. The pain may be constant or can get worse with activity or when you breathe.

Trouble Breathing
If you find yourself feeling short of breath, especially when exercising or being active, ask your doctor to check your lungs. This can also be caused by other health problems, but is one of the earliest symptoms of lung cancer.

These three symptoms are the most common and earliest signs of lung cancer. Everyone is different, and if you notice any change in your health or any trouble breathing, it is important to talk to your doctor. Remember, the sooner you catch cancer, the more likely it is that your treatment will be successful.
