What cancers are associated with smoking?

It causes more than lung cancer — based on current evidence, it can cause cancers of the mouth and throat, voice box, esophagus, stomach, kidney, pancreas, liver, bladder, cervix, colon and rectum, and a type of leukemia (acute myeloid leukemia).
How many different types of cancer can you get from smoking?
Most people associate lung cancer with tobacco but did you know there are 16 cancers that can be caused by smoking? Every time a person takes a puff of a cigarette, 7000 chemicals enter the lungs and spread to other parts of the body, including 69 known carcinogens. Here are some of the facts on smoking and cancer.
Does smoking increase risk of all cancers?
So the statistics are turned around: Smoking accounts for 30 percent of all cancer deaths and 87 percent of lung cancer deaths; the risk of developing lung cancer is about 23 times higher in male smokers compared to non-smokers; smoking is associated with increased risk of at least 15 types of cancer; or that smoking …
Which cancer is not associated with smoking?
Of the many sites of cancer examined, the following were not associated with cigarette smoking: colon, rectum, liver, prostate, kidney and skin (melanoma).
How many cigarettes a day is normal?
On average, respondents in this group considered that smoking can cause cancer only if one smokes at least 19.4 cigarettes per day (for an average reported consumption of 5.5 cigarettes per day), and that cancer risk becomes high for a smoking duration of 16.9 years or more (reported average duration: 16.7).
How harmful is smoking?
Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs. Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis. Cigarette smoking causes most cases of lung cancer.
Can quitting smoking cause cancer?
The good news is that the risk of having lung cancer and other smoking-related illnesses decreases after you stop smoking and continues to decrease as more tobacco-free time passes. The risk of lung cancer decreases over time, though it can never return to that of a never smoker.
How can I prevent lung cancer after quitting smoking?
Quitting reduces your risk of lung cancer, even if you’ve smoked for years. Talk to your doctor about strategies and stop-smoking aids that can help you quit. Options include nicotine replacement products, medications and support groups. Avoid secondhand smoke.

How do we know smoking causes cancer?
The first clues about how cigarette smoke causes cancer came in the 1960s. That’s when scientists found that molecules suspected of being carcinogens could bind to DNA. Since DNA is the blueprint for life, anything that corrupts that blueprint is destined to cause trouble.
