The Common Elements Behind Lung Cancer

by Douglas Grahame

The most prevalent symptoms of lung cancer are persistent coughing, worsening of a pre-existing chronic cough and presence of blood in sputum, unexplained loss of weight, chest pains and difficulties in breathing. These symptoms will vary depending on the location of the patient and the rate at which the tumor spreads. The sad reality is that one cannot identify any early signs or warnings of lung cancer easily.

There are two types of cancer of the lungs: primary lung cancer and Mesothelioma, which is also referred to as secondary lung cancer. Primary lung cancer is usually starts in the lungs. Mesothelioma on the other hand results when the cancer starts in another part or other parts of the body and slowly spreads to the lungs.

Cancer of lungs is categorized into two; that is Mesothelioma and primary lung cancer. Primary lung cancer is that which begins inside the lungs and Mesothelioma, which is also called secondary cancer is usually as a result of another cancer which affected a different part of the body and has now spread into the lungs. The known causes of lung cancer include smoking, viruses, asbestos, radon gas and other genetic risks.

Smoking: Cigarette smoking is by far the major leading cause to lung cancer with over 80% of lung cancer related deaths in the developed world being as a result of cigarette smoking. There are even greater chances of one developing lung cancer if he/ she takes on smoking at a younger age. Non-smokers can also find themselves developing cancer through exposure from the presence of one smoking close to them. Therefore in smoking pipes and cigars, cannabis or as a passive smoker you are likely to develop lung cancer.

Radon Gas Fumes: Radon is a gas that occurs naturally and it passes to building foundations from the soil. If you are exposed to this gas, its concentration varies locally, consider the type of rocks and soil of a given area.

Asbestos: People who have a long contact with asbestos are likely to develop lung cancer especially if they couple it with the smoking of cigarettes. The two combinations are fatal as they increase the chances of developing cancer. Heavy exposure to asbestos lone can also result to lung cancer.

Viruses: In early times, viruses where thought to only cause lung cancer in animal. However, recent studies show that they can cause cancer I humans too. These viruses include JC virus, simian, papillomavirus and others.

Prevention measures such as avoidance of tobacco are cost-effective and better ways of avoiding lung cancer.
