Lung cancer is an uncontrollable growth of cancerous cells in one or both of the lungs. While normal lung tissue cells reproduce and develop into healthy lung tissue, these cancerous cells reproduce rapidly and never grow into normal lung tissue. Tumors begin to form and the lung begins to function improperly. More than 87% of lung cancer is related to smoking. Not all smokers develop lung cancer though. Those who have quit have a lesser chance of getting it than those who are currently smoking. Even for those people who do not smoke has a chance to get this cancer if you are continuous exposed to carcinogens and secondhand smoke.
Lung cancer is estimated to kill more then 154,900 Americans by the end of year 2002. While other cancer incidences are decreasing, lung cancer rates are gradually increasing. From the years 1960 to 1990, the deaths from lung cancer increased over 400%. Even with the advancing technology, there is no certain cure for the lung cancer patients. A new study showed that Anethole Dithiolethione might actually be able to prevent cancer by preventing the growth of cancerous cells on the lungs. It can also destroy the cancer causing cells but this is not proven to work for everyone. If this were to actually work, more people can afford this medication instead of going to surgery or having chemotherapy. .
Secondhand smoke can also cause lung cancer. The taking in of carcinogens and smoke from cigarettes and cigars might have the same or even a worst affect than the smoker himself. In the year 2002, 3,000 people died from breathing in these carcinogens. Since most in some bars and restaurants, people are allowed to smoke, people can inhale the smoke, which might cause a problem to the respiratory system. This is why the ban on smoking in restaurants and bars might be a good affect on society. It might help reduce the deaths from secondhand smoke or maybe reduce the risk of heart disease and asthma.
