Acidosis Causes More Condition_symptoms
Key points
-
- Cigarette smoking causes 87 percent of lung cancer deaths and is responsible for most cancers of the larynx, mouth, esophagus and bladder (see
Question 1 -
). - second-hand smoke is responsible each year for approximately 3,000 lung cancer deaths among nonsmokers (see Question 2 ).
- snuff smoke contains thousands of chemicals, including over 60 substances known to cause cancer (see question 3 ).
- The risk of developing smoking-related cancers and diseases non-cancer increases with the total exposure has been had in life to cigarette smoke (see Question 4 ).
- Smokers can reduce their risk of developing cancer by quitting smoking (see Question 5 ).
- snuff consumption, especially cigarette smoking is the single most cause of death can be prevented in the United States. Cigarette smoking alone is directly responsible for at least one-third of all cancer deaths in the United States each year ( 1 ). Cigarette smoking also contributes to lung, heart, stroke and development of babies with low birth weight (
2 ). Quitting smoking can significantly reduce a person's risk of heart disease and lung, and can limit adverse health effects in children. What are the effects of cigarette smoking on the incidence of cancer? Cigarette smoking causes 87 percent of deaths from lung cancer. Lung cancer is the leading cause of cancer death in both men and women (
1 - ). Smoking is also responsible for most cancers of the larynx, mouth, esophagus and bladder. It also has a close relationship with the development and death from kidney cancer, pancreas and cervix ( 2 , 3 ). Are there any health risks for nonsmokers? health risks caused by cigarette smoking are not limited to smokers. When exposed to secondhand smoke or snuff smoke in the environment (ETS, in English), the risk of nonsmokers for developing lung cancer increases sharply (1
- , ; 2 ). (Second-hand smoke is a combination of smoke given off by the tip the burning cigarette and smoke that smokers are fired from the lungs). According to the Centers for Disease Control and Prevention (CDC), exposure to secondhand smoke causes about 3,000 lung cancer deaths among nonsmokers and is estimated to be responsible for lower respiratory tract infections in 300,000 children each year ( 3 ). The Agency for Environmental Protection (EPA) announced in December 1992 a risk assessment report in which snuff smoke in the environment was classified as Group A carcinogen, ie, a carcinogen found for the man, a category reserved only for the most dangerous agents that cause cancer ( 4 , 5 ). What harmful chemicals are in cigarette smoke? Cigarette smoke contains some 4,000 chemicals, including 60 substances known to cause cancer (carcinogens) in humans (3
- ). In addition, many of these substances, such as carbon monoxide, tar, arsenic and lead, are poisonous and toxic to the human body. Nicotine is a drug that is naturally present in the plant and is primarily responsible snuff of a person's addiction to snuff products, including cigarettes. When smoking, nicotine is rapidly absorbed into the bloodstream and travel to the brain within seconds. Nicotine causes addiction to cigarettes and other products like snuff which is produced by the addiction of heroin and cocaine ( 6 ). How does affect those who smoke cigarettes on exposure to secondhand smoke? The risk of developing smoking-related diseases like lung cancer and other cancers, heart disease, stroke and respiratory disease is related to total exposure you have had in life to cigarette smoke (7
- ). This includes the number of cigarettes you smoke daily, the intensity of their smoking (ie, the size and frequency of puffs), the age at which started smoking, number of years a person has smoked and exposure to secondhand smoke snuff hand. What effect does smoking cessation on the risk of developing cancer and other diseases? Smokers who quit live longer than those who continue to smoke. Moreover, as soon as you stop smoking, the greater the health benefits (1
- ). Quitting smoking reduces a person's risk of dying from cancer and other smoking-related diseases ( 1 ). How much risk is reduced depends on the number of years a person smoked, the number of cigarettes smoked in one day, the age at which smoking began and the presence or absence of disease at the time of quitting. Research has shown that people who quit smoking before age 35 reduce their risk of developing a disease related to snuff by 90 percent ( 1 ). Even smokers who quit before age 50 significantly reduced their risk of dying from a disease related to snuff ( 1 ).
