Recognizing The Symptoms Of Lung Cancer

In general, lung cancer is a broad term that encompasses several different types of conditions that all result from the abnormal growth of cells in that part of the body. As cells age, most die off. However, some cells continue to grow and eventually become damaged or deformed. These cells accumulate over time and this is what we know as cancer. In some cases, the accumulation of abnormal cells grow into tumors, but this isn't always the case. When it comes to lung cancer, a tumor may develop, but it's the spread of abnormal cells that poses the greatest risk.
