What is Lung Cancer?

Breathing! It’s something that we do every day and pay very little attention to. Yet, when something goes awry in the respiratory system, there is no denying the fatal consequences that may occur. Lung Cancer is the leading form of cancer that leads to fatalities in both males and females throughout the United States. This includes breast cancer, colon cancer and even prostate cancer fatalities combined. The reason that Lung Cancer is so prevalent in the United States is because of the nation’s addiction to smoking.

Lung Cancer forms when lung cells begin to divide at an abnormal rate and mutate. The cells begin to divide rapidly and in return the excess tissue creates tumors. The lungs are a vital component of the Respiratory System. Our lungs breathe in oxygen and in return they release Carbon Dioxide. This is the normal function of the Respiratory System. However, when Lung Cancer forms, the system goes awry. There are two classifications for Lung Cancer. These are: Non-Small Cell Lung Cancer and Small Cell Lung Cancer. Both Non- Small and Small Cell Lung Cancers are named due to the way the cells appear when examined under a microscope. Non- Small Cell Lung Cancer is more common and is divided into three main types or categories. These are: Squamous Cell or Epidermoid Carcinoma, Adenocarcinoma, and Large Cell Carcinoma.

Small Cell Lung Cancer is not as common as Non-Small Cell Lung Cancers and may also be referred to as Oat Cell Cancer, due to the fact that the cancer cells bear an oval shape. This type of cancer is fast spreading and grows quickly. It also spreads to other organs more rapidly.

Though Lung Cancer is the most common and fatal form of cancer seen today, it is also the most preventable. There are a number of environmental causes that contribute to the development of the disease and by preventing exposure to these; you can significantly lower your risk of developing Lung Cancer.
