Cigarette smoking accounts
for at least 30% of all cancer deaths. It is a
major cause of cancers of the lung, larynx
(voice box), oral cavity, pharynx (throat), and
esophagus, and is a contributing cause in the
development of cancers of the bladder, pancreas,
liver, uterine cervix, kidney, stomach, colon
and rectum, and some leukemias.
About 87% of lung
cancer deaths are caused by smoking. Lung cancer
is the leading cause of cancer death among both
men and women, and is one of the most difficult
cancers to treat. It is very hard to detect when
it is in the earliest, most treatable stage.
Fortunately, lung cancer is largely a
preventable disease. Groups that promote
nonsmoking as part of their religion, such as
Mormons and Seventh-day Adventists, have much
lower rates of lung cancer and other
smoking-related cancers.
Other Health Problems
But cancers account
for only about half of the deaths related to
smoking. Smoking is also a major cause of heart
disease, aneurysms, bronchitis, emphysema, and
stroke, and contributes to the severity of
pneumonia and asthma.
Tobacco has a
damaging affect on women's reproductive health.
It is associated with reduced fertility and
increased risk of miscarriage, early delivery (prematurity),
stillbirth, and low birth weight in infants. It
has also been linked to sudden infant death
syndrome (SIDS).
Smoking has also
been linked to a variety of other health
problems, including cataracts, hip fractures,
and peptic ulcers.
Lung cancer is the leading cause of cancer death in the US for both men and women. (Source: Cancer Facts & Figures 2004)
Lung cancer is the most preventable form of cancer death in our society. (Source: Cancer Facts & Figures 2004)
87% of lung cancer deaths can be attributed to tobacco use. (Source: Cancer Prevention and Early Detection 2004)
Lung cancer estimates for 2004 (Source: Cancer Facts & Figures 2004):
New cases: 173,770
Males: 93,110
Females: 80,660
Deaths: 160,440
Males: 91,930
Females: 68,510
Besides lung
cancer, tobacco use also causes increased risk
for cancer of the oral cavity, nasal cavities,
larynx, pharynx, esophagus, stomach, liver,
pancreas, kidney, bladder, uterine cervix, and
myeloid leukemia. (Source: Cancer
Prevention and Early Detection 2004)
In the US,
tobacco use is responsible for nearly 1 in 5
deaths or an estimated 440,000 deaths per year
during 1995-1999. (Source: Cancer Facts &
Figures 2004)
In 2004, more
than 180,000 cancer deaths will be caused by
tobacco use. (Source: Cancer Prevention and
Early Detection 2004)
Tobacco use
accounts for at least 30% of all cancer deaths
and 87% of lung cancer deaths. (Source:
Cancer Facts & Figures 2004)
In 2002, an
estimated 45.8 million US adults (22.5% of the
population) were current smokers. (Source:
MMWR Morb Mortal Wkly Rep.
2004;53(20):427-431. To be published in
Cancer Facts & Figures 2005.)
More than 80% of
smokers surveyed in 1991 began to smoke before
age 18, and 35% had become daily smokers by
age 18. (Source: Cancer Facts & Figures
2004)
Each year,
secondhand smoke may be responsible for about
3,000 lung cancer deaths in nonsmoking adults
and an additional 35,000 to 40,000 cases of
heart disease in people who are not current
smokers. (Source: Cancer Facts & Figures
2004)
Cigars contain
many of the same carcinogens that are found in
cigarettes. Cigar smoking, which has steadily
increased since 1993, causes cancer of the
lung, oral cavity, larynx, esophagus, and
possibly the pancreas. (Source: Cancer
Facts & Figures 2004)
Among adults age
18 and older, national data showed 6% of men
and 1% of women were current users of chewing
tobacco or snuff. (Source: Cancer Facts &
Figures 2004)
Oral cancer
occurs several times more frequently among
chewing tobacco or snuff users compared with
non-tobacco users. (Source: Cancer Facts &
Figures 2004)
Smoking-related
medical costs totaled $75.5 billion in 1998
and accounted for 8% of personal health care
medical expenditures. This translates to
$1,623 in excess medical expenditures per
adult smoker in 1999. (Source: Cancer Facts

"I had quit for a while and started up again 3 years ago. The hypnosis worked so well I wish I had
used it the first time. This time I am done for good!"
- T.S. Encinitas
"I am sending my Sister and Brother-in-law to see you for smoking as
well. They couldn't believe how simple it was for me, and I am
thrilled with the results. Thanks!
- K.C. Sorrento Valley
"I was skeptical after 20 years of smoking, but you were right, I was
definitely ready to be done with the habit. I am never going
back."
- F.T. Cardiff
"I went to a bar with friends and
just laughed at the people outside smoking. It felt amazing to say,
"No thanks, I don't smoke." Yes!!!"
