10 Early Symptoms of Lung Cancer

The number one cause of cancer deaths among men and women globally each year is lung cancer. In 2019, it's estimated that approximately 228,000 new cases were diagnosed, resulting in approximately 142,000 deaths. The general survival rate is poor because the cancer is usually not diagnosed until it is at an advanced stage.

There are two kinds of lung cancer. The first—and most common—is non-small cell lung cancer (NSCLC). This form accounts for approximately 80-85% of all lung cancers and is most often found in the lung tissue. The most important factor in survival rate for this type is the stage at which the cancer is diagnosed. Radiation therapy can produce a cure in a small percentage of patients and helps to relieve symptoms.

The second kind—small cell lung cancer (SCLC)—can most often be found in the bronchi. 98% of all small cell lung cancer cases can be attributed to tobacco smoking. This cancer can be fatal within 2-4 months of diagnosis. It spreads more rapidly than NSCLC, however, it is the most responsive cancer to radiation therapy.

The number one cause of lung cancer is tobacco smoking, which accounts for approximately 90% of all lung cancer diagnoses. Other causes are second-hand smoke, exposure to certain toxins and/or a family history of cancer. The best way to avoid being diagnosed with lung cancer is to quit smoking and stay away from others who smoke.

The best chance for surviving lung cancer is to have it diagnosed as early as possible, before it begins to spread. We have done the research and compiled the top ten early signs of lung cancer for you.
