Lung cancer is one of the most common forms of cancers. Lung cancer arises when a series of mutations in normal lung cells cause them to become abnormal and out of control. Lung cancer is the leading cause of cancer death In the United States in both men and women, but it is also the most preventable kinds of cancer. Almost 80% of all lung cancer deaths are thought to be caused by smoking tobacco. It is very rare for someone who has never smoked to be diagnosed with lung cancer. The risk for lung cancer among non-smokers is way lower than the risk of lung cancer in smokers. The more a person smokes and the more packs a person smokes a day, the greater the risk will be of being diagnosed with lung cancer. Cigar smoke and pipe smoke are almost as likely to cause lung cancer as cigarette smoking. Smoking low-tar or light cigarettes as an alternative to decrease the chances of the risk of lung cancer doesn’t help, considering the fact that these cigarettes increase the risk of lung cancer as much as regular cigarettes. There is also concern that menthol cigarettes could increase the risk even more, as the menthol has been known to allow smokers to breathe inhale more deeply. Secondhand smoke (breathing in the smoke from other smokers) is also a risk factor of lung cancer. Secondhand smokers have at least a 20% - 30% chance of being diagnosed with lung cancer. Secondhand smoke is thought to be the cause of over 3000 deaths from lung cancer a year. In my opinion this may be why smoking in public is nearly extinct. Radon which is an occurring radioactive gas that forms from the breakdown of uranium in soil and rocks. It can’t be smelled, seen, or tasted. According to the US Environmental Protection Agency (or the EPA) radon is the second leading cause of lung cancer, and it is the leading cause of lung cancer among non-smokers. There is so little radon outdoors to be considered dangerous, but indoors it can be more concentrated. When radon is breathed in it enters the lungs exposing them to small amounts of radiation, which in turn increases a person’s chance of lung cancer. The lung cancer risk from radon is much lower than that from tobacco smoke, but the risk from radon is

80% of lung cancer cases are caused by smoking, allowing lung cancer to be the most common form of cancer. Cigarette smoke contains chemicals that interfere with the body’s ability of filtering air and cleaning out the lungs Smoking also causes overproduction of mucus, meaning smokers are more likely to have “smokers cough” (chronic bronchitis) DAMAGE Destroys normal lung structure Smoking breaks down the elastic walls of small airways within the lungs, reducing the amount of lung tissue available…

Lung Cancer Essay

Lung Cancer Lung cancer takes years to develop. It results from the uncontrolled growth of abnormal cells in one or both lungs. These cancer cells form lumps and disrupt the lungs, the breathing tubes (bronchi) or both, at times interfering with their normal function. Unfortunately, lung cancer is often not discovered until it has spread (metastasized) throughout the body. Sometimes, however, lung cancer is detected earlier through a chest X-ray or other exam that has been conducted for an unrelated…

medicine, lung cancer continues to be the most common cause of cancer-related deaths. Non-small-cell lung cancer (NSCLC) accounts for 85% of all lung cancers. Researchers have identified epidermal growth factor receptor (EGFR) mutations that increase the risk for lung cancer in smokers and non-smokers. New pharmacological therapies are aimed at suppressing these oncogene and decreasing the rate of metastasis in certain types of lung cancers. These findings can be useful in not only lung cancer therapies…

The Cause Of Lung Cancer

second biggest cause of lung cancer. Radon is a naturally occurring, colorless, odorless, radioactive gas noble gas. It is the product of radioactive decay of the elements uranium, thorium, and radium in rocks and soil. Radon is present in nearly all air but in small amounts. When inhaled radon is mostly exhaled again. However, sometimes the radon atoms would decay while inside the lungs and release alpha particles and daughter nuclei. The daughter nuclei deposited in the lungs and airways would undergo…

Lung cancer is the common cancer worldwide, with 1.8 million cases and 1.6 million deaths in 2012. It surpassed breast cancer to become the leading cause of cancer related deaths in women in 1987. Deaths due to lung cancer have also increased approximately 3.5% between 1999 and 2012. While the death rate of men have come to a plateau, women’s death rates are still rising. In 2012 alone 86,740 men and 70,759 women had died from lung cancer. Also among 402,326 Americans living today have been diagnosed…

Lung cancer was a relatively rare disease at the beginning of the 20th century but by the end of the century, it had become the main cancer-related public health problem worldwide. (Wingo et al. 2003). Cancer is recognized as an ‘unbiased killer’ because it knows no gender, age or race of its victims. This disease begins in the cells of the body. In normal conditions, the cells grow and divide as the body needs them. However, this systematic process is interrupted when gene changes make one cell…

Lung cancer, like other types of cancer, is the result of an abnormality in the cell of the body. This type of cancer can grow in any part of the lung, although 90-95% of lung cancers are known to arise from the cells lining the smaller and the larger airways. What are the Lung Cancer Risk Factors Normally, the human body has a system that balances and checks the cell growth so that the cells are divided to produce new cells when needed. If there is a disruption in this body system, there can be…
