What Exactly Are Carcinogens Cause Cancer?

substances is one of the most clearly demonstrated links between environmental exposures and cancer. The good news is the bladder cancer is probably a completely preventable disease, if exposure to the carcinogenic substances is limited or eradicated.

In America, there are many studies on the relationship between tobacco use and cancer that was conducted. These studies estimate that about a third of cancer deaths related to tobacco use. Tobacco causes approximately 90% of all deaths from lung cancer and smoking also causes cancer in many other parts of the body like pharynx, larynx, esophagus, pancreas, uterus, cervix, kidney, bladder, colon and rectum. To reduce the risk of tobacco-related diseases, the health educators may find information on the Web site “http://www.nobutts.org” to give their audiences necessary information to help them quit smoking.

For example, Iodine 131 causes thyroid cancer. It is a substance that dissolves into liquid such as water and milk. Other chemicals such as Strontium-90 and Cesium 147 as well get into water, milk, soil, food and vegetables that we eat and cause bone, skin cancer and leukemia. Chemicals like Strontium-90 and Cesium-147 remain for up to 200 to 300 years in the atmosphere (CancerSource.)

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

Cancer results from abnormal, unregulated cell growth which can create physiological impairments in body tissues (1). Two adverse characteristics of cancer cells include the ability to invade other tissues and the inability to die (2). Cells generally become cancerous due to changes in gene expression and subsequent errors in protein function (2). These faults in genes and physiology can be caused by mutations which can result from exposure to carcinogens. One of the most common substances associated with carcinogens (though not carcinogenic itself) that promotes cancerous growth is nicotine (3). Nicotine has been shown to stimulate growth, promote the creation of blood vessels (angiogenesis), and prevent cell death through nicotinic acetycholine receptors (nAChRs)(3). In mice, for example, nicotine increased levels of angiogenesis by altering mechanisms involved in a heightened response of the COX-2, prostacyclin, VEGFR-2, MMPs, uPA, and e-NOS protein activity (3). These increases in cell sensitivity to these particular factors stimulated by nicotine promoted cell growth and migration to other tissues (3).

Some of the pollutants released include: toluene, benzene, xylene and ethyl benzene, ground level ozone (also known as smog), nitrogen oxides, carbon monoxide, and formaldehyde. Exposure to these pollutants are known to cause short-term illness, organ damage, nervous system disorders, cancer, birth defects and even death in some cases. Some of the cancer causing are this; Dioxin is formed when chlorine breaks down, and can be found in both water and air. Dioxins are known human carcinogens and endocrine disruptors. One dioxin has been classified by the International Agency for Research on Cancer (IARC) and the Environmental Protection Agency (EPA) as a known human carcinogen. Organic solvents are a class of chemicals that includes chlorinated and other solvents, including toluene, methylene chloride, trichloroethylene and formaldehyde. Sources of exposure include outdoor and indoor air pollution, waste incineration, cleaning products and some cosmetics. They are also used in the manufacture of computer parts. Many pesticides that are included in the fluid, including herbicides and other pest-killing poisons, have been labeled as human or animal carcinogens. A report demonstrated that lifetime use of residential pesticides may be associated with an increase

There are approximately six hundred ingredients in cigarettes, when burned a chemical reaction occurs and they release more than seven thousand chemicals. At least sixty-nine of the chemicals have been proven to cause cancer, and most are poisonous. Cigarettes are composed of nicotine, carbon dioxide, irritants, and tars as wells as formaldehyde, arsenic, and DDT. If a human person ate one pack of cigarettes, they would be instantly killed. Furthermore, there are enough of these poisonous chemicals that

The high mortality rates are the primary reason why many people are actively petitioning for the universal ban of tobacco. In a recent article published by the American Lung Association they found approximately 600 ingredients in cigarettes. When burned, they create more than 7,000 chemicals. Roughly 69 of those chemicals are known to be poisonous, cause cancer, and many other diseases. Tobacco usage accounts for more than 30% of

According to statistics in the 20th century the world over 100 million people died of tobacco-related diseases. However, the proportion of smokers has not decreased, or even increased due to the limited understanding of the harmful effects of tobacco smoke, knowledge is limited.

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.

Smoking is one of the leading causes of mortality and morbidity. The exposure to tobacco smoking negatively impacts the health of an individual over time by increasing the risks of developing diseases of the respiratory and circulatory systems (Ministry of Health, 2005). In particular, smoking is the leading cause of lung cancer. With repeated exposure, inhalation of tobacco into the lungs causes a build up of tar, altering lung tissue (Cockerham, 2007; Marmot and Wilkinson, 2006). This direct use of tobacco accounts for the death of 5 million people around the world. In the United States, 444,000 deaths per year are attributed to smoking, were 13 years of life lost for a male smoker and 14.5 years lost for a female (Cockerham, 2007; WHO, 2012). In New Zealand, tobacco use is the main cause of preventable death, contributing to around 4600 deaths

One chemical agent that results in cancer is ethanol, or alcohol. Alcohol is one of the most prevalent drug choices nationwide. The effects of alcohol differ with each individual person. It depends on age, gender, percent body fat, and the rate of metabolism (). A few of the cancers that alcohol can cause include oral, colorectal, breast, and liver.

"These days, there are up to 500 chemicals in an average human body that were not found in humans before 1920."1 Several forms of environmental pollution have the ability to intoxicate human bodies with unwanted chemicals. Pollution exists when the environment cannot break down or eliminate an object without creating negative effects. Intoxicating bodies is just one of the several harmful effects that pollution has, specifically, in North America. Pollution causes other problems such as: methane production, health issues, acid rain harmful to ecosystems, and water and soil contamination. Environmental pollution harmfully

Brain cancer is one of the dangerous cancer types that cause rapid deterioration of health and death. Smoking in young women is increasing as a trend and it requires a coordinated approach. The women should be made aware of the consequences of smoking on their immediate health as well as the long term effects on them and their children. The smoking women are prone to numerous cardiovascular diseases, diabetes, lungs, and respiratory issues. According to Zheng, Cantor, Zhang, Chiu, and Lynch (2001) even there is minimal evidence that there is a direct link of smoking and brain cancer however the intake of N-nitroso compounds can cause brain cancer. The tobacco intake through various methods including smoking causes various health issues.

Their are these chemicals called Carcinogens that are often found in food. They are not in the food naturally, but i thought it was still important to include into my conclusion since it is something that happens everyday. Carcinogens is a broad topic considering they are also found in cigarettes, it is surprising that they cold also be found in our food. However, Carcinogens like Dioxin are caused to be in your food by the plastic that surrounds some foods and drinks. Preventing this is pretty simple don't freeze your plastic water bottles as this releases dioxins in the plastic and don't heat fat-containing food in the microwave using plastic containers. Other Carcinogens such as Aflatoxins are detected occasionally in milk, cheese, corn, peanuts, cottonseed, nuts, almonds, figs, spices, and a variety of other foods and feeds this is caused by the feed given to the animals or put into the soil to improve efficiency. Another thing about food and cancer is; “ Eating large amounts of processed meats may increase the risk of colon cancer secondary to nitrates added to the food. that is why you see nitrate free lunch meat and hot dogs now.” Also, a report from the American Cancer Society stated that "the regular consumption of charred well-done meat showed an increase in the risk of pancreatic cancer". This could also relate back to obesity causing cancer. Overall
