Our body is made up of cells, which is the body’s basic unit of life. Usually cells grow, divide, and produce more cells as needed to keep the body healthy. Sometimes this process can happen to rapidly and the body produces more cells than needed. The mass of unneeded cells forms a growth called a tumor. Not all tumors are detrimental to one’s health. Tumors can either be benign or malignant. Benign tumors are not cancerous. They can often be removed surgically. Once a benign tumor is removed, it does not return. They are rarely a threat to life. Malignant tumors, on the other hand are cancerous. These cancerous cells can break away and break apart the surrounding tissue. These cells can enter the blood stream and invade other parts of the body through a process

Lung disease such as tuberculosis increases a person’s chance to contract lung cancer. Last but not least is a personal history of lung cancer. Someone who has had lung cancer before is more likely to have it again than a person who has not had it before. Research continues to be done on the causes of lung cancer. To help find the cause of symptoms, a doctor will evaluate a person’s medical history, smoking history, and exposure to environmental and occupational substances, and family history of cancer. There are many different types of detection tests that can be done. A bronchoscopy is a test in which a doctor puts a bronchoscope into the mouth or nose of a person, down the windpipe to look into the breathing passages. A thoracentesis is a process in which a doctor uses a needle to remove a fluid sample that surrounds the lungs to check for cancer cells. A thoracotomy is a major operation in which a person’s hest is opened to check for the presence of cancer.

The lungs are a pair of sponge-like, cone-shaped organs that are the largest part of the respiratory system. The right lung has three sections called lobes. It is larger than the left lobe which only has two lobes. When a person breaths, the lungs take in oxygen which allows cells to perform the tasks necessary for life. As we exhale, carbon dioxide is released from our body. Carbon dioxide is a waste product produced by the cells.

The are many factors that put people at risk for lung cancer. Cigarettes, cigars and pipes, and environmental tobacco smoke are all related to smoking. There are other non-smoke related aspects of lung cancer. Pol
