Lung Cancer Essay

The leading cause of death in America is lung cancer. Lung cancer is ranked top 10 fatal cancers in the United States. There are many types of ways to get lung cancer. There is radon gas it occurs outdoors naturally. Then there is second hand smoke that comes from other people smoking. People are even getting lung cancer from cancer causing agents, this happens from carcinogens. You can also get it from air pollution indoors and outdoors. Also there are gene-mutations that form cancer causing cells. Then there is the one everyone blamed lung cancer is smoking.

Lung cancer dates back to 1761 when it was called disease. In 1878 only 1% of the populations were thought to have it. When the 1900s came by that number rose to 15%. There was only 374 case filed by 1912. It wasn’t until 1929 when smoking became a factor in lung cancer. Fritz Lickint was the first person to tell the public about the dangers of smoking that which went into a campaign act to tell worldwide about the dangers of smoking.

The Surgeon General of the US finally made the recommendation that people should stop smoking to improve their health and wellbeing. In the 1950 scientist introduced radical radiotherapy to reduce the size of cancerous cells.

Radon gas was found in the 1870s, when some scientists were mining for ore in Ore Mountains in Schneeberg, Saxony. The area has a high content of radon in the tunnels because the area has been mined since the 1470s. The scientists later discovered that 75% of the miners died from lung cancer but it did not shut down the tunnels until 1950.

Radon gas is currently the leading cause of lung cancer in the nonsmokers. Radon gas is harmless in small amounts but sometimes becomes concentrated in homes built on soil wi...

...per cubic meter of air, they found. While people who smoke may also live in more polluted areas, the large group of the studies showed that even so, pollution can raise even a non-smoker’s risk of cancer.

The cancer cells from gene-mutation. Scientists now know some of the risk factors for lung cancer can cause certain changes in the DNA of lung cells. These changes can lead to not normal cell growth and, sometimes, cancer. DNA is the chemical in each of our cells that makes up our genes and how our cells function. People usually look like their parents because they are the source of our DNA. But DNA affects more than how we look; it also can affect our risk for developing certain diseases, including some kinds of cancer like lung cancer etc…Some people inherit DNA mutation from their parents that greatly increase their risk for developing certain cancers.
