Research on Lung Cancer Risk Factors

Active smoking and disease relationship was first studied as case-control studies in Germany during 1939 and 1943which revealed a strong association between active smoking and lung cancer [1]. After that large number of studies were conducted which established relationship of tobacco smoke with

It has been proven that smoking is the cause of 30% of general cancer deaths and 80% of lung cancer deaths in the U.S. Lung cancer has also been found to be the biggest cause of cancer deaths among breast cancer, prostate cancer, and ovarian cancer. This year alone, 190,500 of about 600,900 cancer deaths will be caused by smoking tobacco. This means that one in every three cancer patients will die due to tobacco products. In fact, smoking tobacco caused such high amounts of lung cancer that tobacco companies are legally required to include a surgeon general’s warning that outlines the potential of developing cancer on their packaging. The numbers and warnings of smoking-related lung cancer can be seen everywhere from statistics to the companies themselves being held liable for the illnesses their products

Lung cancer can be caused by multiple factors and many factors can work together to cause someone to have lung cancer. Besides smoking, radon, secondhand smoke, the environment and someone’s occupation can all cause lung cancer. As we already know smoking is the number one cause of lung cancer cases worldwide and over forty-three million people just in the United States smoke cigarettes. There are more than fifty chemicals in tobacco smoke that are ingested each time someone smokes. Some of these chemicals include benzene (which can be found in pesticides and gasoline), Formaldehyde (which preserve dead bodies), pesticides (which are found on lawns and gardens) and Tobacco-specific N-nitrosamines (Martin, 2012). When a person inhales the chemicals in cigarettes, they inhale thousands of poisons, toxic metals, and

According to the Healthy People 2020, each year, approximately 480,000 Americans die from tobacco-related illnesses. Further, more than 16 million Americans suffer from at least one disease caused by smoking. (U.S. Department of Health and Human Services, 2012). The effect of cigarette smoking is alarming. Use of tobacco in the form of smoking is not only dangerous to the one who is smoking but also to a non-smoker. Tobacco harms a human physically and mentally. Major cause of lung cancer is smoking. It is important to prevent the use of tobacco because it is the largest preventable cause of diseases and death in the United States. According to Chin, Hong, Gillen, Bates and Okechukwu (2012) Blue-collar workers smoke at higher rates than white-collar workers and

The years following the release of the first Surgeon-General’s report on tobacco use in 1964 have recorded successes and setbacks for public health officials. The report closely followed a release from the tobacco industry in 1954 titled “Frank Statement to Tobacco Users” which basically said that there was no cause for alarm. It rebutted the findings from a study on mice which showed the link between tobacco smoking and lung cancer. It insisted that there was not enough proof or evidence to state that there was a direct link between tobacco smoking and lung cancer.

Lung cancer is a very common to be diagnosed with and harmful to anyone who is exposed to many resources around the world: smoking (first hand and second hand) and pollution. Any resource that is made up of chemicals that are exposed into the air that people breathe, give the risk of affecting others with lung cancer. However, since smoking is the most popular way to cause lung cancer, many people are exposed to it from either firsthand or second hand. First hand smoking is when the person being affected is indirect contact with the source that is giving off the toxins, while secondhand is when the one being affected is not directly connected to the main source. Either way the chemicals and toxins that come from harmful resources soon will build up and affect one’s normal body

Lung cancer occurs due to cells in a person’s lungs that multiple at a rapid pace, which form a malignant tumor. These tumors in the lungs take away important necessities such as oxygen, and nutrients; diminishes the ability of the tissue to properly function. One of the most type of common lung cancers is Adenocarcinoma, which make up to forty percent of these cases. Smoking is the primary reason for Americans to be diagnosed with lung cancer, with a cigarette containing more than 4,000 chemicals that have permanent damage to the lungs causing long term effects (Conrad 2016).

One of the leading and most avoidable risk factors of lung cancer is smoking. In both males and females smoking is linked to a higher incidence of lung cancer at an increase of 23% and 13% respectively. Smoking not only increases the likelihood of lung cancer, but has shown a correlation in higher risk of other cancers such as oral, laryngeal, pharyngeal, esophageal, pancreatic, ovarian, and multiple more. As a whole,

Everyone knows cancer is the second leading killer in the United States. As people, we try our best to adapt when we hear a loved one has cancer. The question, “Why?” or “How?” always seems to come across our minds when hearing the diagnosis. Learning these common causes and risk factors may reduce a person’s chances in getting cancer. The most common mainstream product sold to cause cancer is cigarettes. ”Dangerous chemicals are found in tobacco use such as nicotine, Benzene, and Menthol (wood alcohol). Radioactive materials are in the tobacco leaves used to make cigarettes and cigars. Studies have shown the connection between tobacco products and lung cancer. Did you know? Lung cancer is one of the most preventable diseases that exist.

Over decades, lung cancer globally continues to be the leading killer in both genders. In the United States, smoking is responsible for 90% lung cancer deaths in men and about 80% in women. About 15 decades ago, lung cancer was not considered as the leading killer because it was an extremely rare disease about 1% in total of cancer cases. However, by the year 1927, the percentage increased into 14%. During World War I, many soldiers and civilians started smoking to release stress. Eventually, that made the lung cancer rate and smoking addiction in the population started to increase. In a research that published in 2001, lung cancer annually kills over one million people worldwide (Witschi, 2001). The death rate, which caused by lung cancer,

Lung cancer was once a very rare disease, this disease was so rare that doctors thought that it was a once-in-a-lifetime oddity. Towards the end of the 19th century cigarettes and tobacco become popularised, causing a global lung cancer epidemic. In 2014, an estimated 221,000 adults in the United States will be diagnosed with lung cancer, (115,610 men and 105,590 women). Lung cancer is the second most common cancer in the US. The one-year survival rate is 44%, the five-year survival rate is 17% (cancer). The cigarette is the deadliest artifact in the history of humans. Cigarettes cause around 1 lung cancer death per 3 or 4 million smoked, this is why the epidemic is so large today. Cigarettes cause about 1.5 million

Lung cancer is the leading cause of cancer-related mortalities in the world. An astounding average of 1.6 million deaths occur due to lung cancer yearly (1). Lung cancer is classified into two types: small cell and non-small cell lung carcinoma (NSCLC), where 85% of lung cancer cases are NSCLC. NSCLC has several different histologic subtypes, some of which are: squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Of the three, adenocarcinoma accounts for more than 50% of NSCLCs, making it the most common subtype (2).

The number one factor for getting lung cancer is smoking tobacco. Smoking causes cancers because the tobacco changes our DNA and
