Tobacco and Cancer – An Introduction
The 1982 US Surgeon General’s Report states, "Cigarette smoking is the major single cause of cancer mortality in the United States." This statement is as true today as it was in 1982. The following information has been excerpted from materials developed by the American Cancer Society. It is provided in English and Spanish to make sure that no one – despite their language proficiency – misses an opportunity to be informed about the health dangers of smoking. This information can help you find out how tobacco increases your risk and where you can go to get help quitting.
Harmful Effects of Tobacco.
It’s extremely important that you know how cancer and disease are caused by cigarettes, cigars, and smokeless tobacco. You must also learn about secondhand smoke, workplace restrictions, and tobacco's effects on teenagers. You can also check out Frequently Asked Questions (FAQ) for information about smoker's cough and much more.
Smokeless Tobacco Is Highly Addictive and No Safer Than Smoking
Many people are under the impression that chewing tobacco or snuff are safer than smoking. There's no burning cigarette in your mouth or cloud of smoke--just a "dip" of finely-ground tobacco (snuff) placed between the gum and cheek or a "chew." In 1986, the U.S. Surgeon General concluded that the use of smokeless tobacco is not a safe substitute for smoking cigarettes or cigars, as this product can cause various cancers and noncancerous oral conditions, and can lead to nicotine addition. Some of these conditions are listed below.
* Cancer of the mouth and pharynx
* Leukoplakia (white sores in the mouth that can lead to cancer)
* Gum recession, or peeling back of gums
* Bone loss around the teeth
* Abrasion of teeth
* Bad breath
The most serious health effect of smokeless tobacco is increased risk of cancer of the mouth and pharynx. Oral cancer occurs several times more frequently among snuff dippers than with non-tobacco users. Cancer of the cheek and gums may increase nearly 50-fold among long-term snuff users.
Second Hand Smoke - What Is It?
Secondhand smoke, also known as environmental tobacco smoke (ETS) or passive smoke, is a mixture of two forms of smoke from burning tobacco products:
Sidestream smoke: smoke that comes from a lighted cigarette, pipe, or cigar
Mainstream smoke: smoke that is exhaled by a smoker
When nonsmokers are exposed to second hand smoke it is called involuntary smoking or passive smoking. Nonsmokers exposed to secondhand smoke absorb nicotine and other compounds just as smokers do. The greater the exposure to second hand smoke, the greater the level of these harmful compounds in your body.
