Smoking
and Cancer - and Why you should consider Hypnotherapy
Introduction
It is estimated that one in three people will develop cancer at some stage
in their lives and that one in four will die from the disease. In 2000,
there were 42,800 cancer deaths in the UK attributable to smoking: approximately
a third of all cancer deaths. The UK Government has set a target (for
England) to reduce the cancer death rate in people aged under 75 by 20%
by 2010. The route to achieving this is set out in the National Cancer
Plan which includes targets to reduce smoking. Cigarette smoking is an
important cause of cancers of the lung, larynx (voice box), pharynx (throat),
oesophagus, bladder, kidney and pancreas. A recent review by the International
Agency for Research on Cancer found that, in addition to these cancers,
smoking is a cause of cancer of the nasal cavities and nasal sinuses,
stomach liver, cervix and myeloid leukaemia.
Hypnotherapy
to prevent Bladder cancer
Tobacco smoking is the principal preventable risk factor for bladder cancer
in both men and women. It is estimated that current smokers are two to
five time more likely to develop bladder cancer than non-smokers. As for
lung cancer, the risk is associated with both the dose and duration of
smoking, while cessation of smoking reduces the risk.
Hypnotherapy to prevent Breast cancer
Some studies have demonstrated a link between both active and passive
smoking and breast cancer. The IARC review concluded that most epidemiological
studies have found no association between active smoking and breast cancer
but since its publication a new study found that among women who had smoked
for 40 years or longer the risk of breast cancer was 60% higher that that
of women who had never smoked. Among those who smoked 20 cigarettes or
more a day for 40 years, the risk rose to 83%.
Hypnotherapy
to prevent Cancers of the mouth and throat
Smoking cigarettes, pipes and cigars is a risk factor for all cancers
associated with the larynx, oral cavity and oesophagus. Over 90% of patients
with oral cancer use tobacco by either smoking or chewing it. The risk
for these cancers increases with the number of cigarettes smoked and those
who smoke pipes or cigars experience a risk similar to that of cigarette
smokers. In total, 4400 new cases of oral cancer were recorded in 2001s.
(“Oral cancer” includes cancers of the lip, tongue, mouth
and throat.)
Heavy smokers
have laryngeal cancer mortality risks 20 to 30 times greater than non-smokers.14
People who drink alcohol and smoke have a much higher risk of oral and
pharyngeal (throat) cancers than those only using tobacco or alcohol.
A US study revealed that among consumers of both products the risk of
these cancers was increased more than 35-fold among those who smoked forty
or more cigarettes a day and took more than four alcoholic drinks a day.
It has been estimated that tobacco smoking and alcohol drinking account
for about three quarters of all oral and pharyngeal cancers.
Hypnotherapy
to prevent Cervical
cancer
Cancer of the cervix has been found to be associated with cigarette smoking
in many case-control studies. Until recently, scientists had been unable
to decide whether the relationship was causal or due to confounding factors
such as the number of sexual partners. A study in Sweden investigated
whether environmental factors such as smoking, nutrition and oral contraceptive
use were independent risk factors for cervical cancer and found that smoking
was the second most significant environmental factor after human papilloma
virus (HPV). The IARC review concludes that there is now sufficient evidence
to establish a causal association of squamous-cell cervical carcinoma
with smoking.
Hypnosis to prevent Colorectal cancer
According to the IARC review, there is some evidence that the risk of
colorectal cancer is raised among tobacco smokers. However, it is not
possible to conclude that smoking is a cause of colorectal cancer. This
may be due to inadequate adjustment for confounding factors which could
account for some of the small increase in risk that appears to be associated
with smoking.
Hypnosis to prevent Kidney cancer
Kidney cancer has consistently been found to be more common in smokers
than in non-smokers and there is now sufficient evidence to show that
smoking is a risk factor for the two principal types of kidney cancer.
There is a dose-response relationship with increasing numbers of cigarettes
per day and risk appears to drop after smoking cessation. Approximately
24% of kidney cancer cases in men and 9% in women can be attributed to
smoking.
Hypnosis to prevent Leukaemia
Smoking is causally associated with myeloid leukemia in adults but not
to lymphoid leukemia. A French study of patients with newly diagnosed
acute myeloid leukemia concluded that cigarette smoking had an adverse
effect on survival in acute myeloblastic leukemia (AML), by shortening
complete remission duration and subsequent survival.
Hypnotherapy to Prevent Liver cancer
Large case-control studies have demonstrated an association between smoking
and risk of liver cancer. In many studies, the risk increases with duration
of smoking or number of cigarettes smoked daily. Confounding from alcohol
can be ruled out in the best case-control studies, by means of careful
adjustment for drinking habits. As association with smoking has also been
demonstrated among non-drinkers. The IARC review concludes that “there
is now sufficient evidence to judge the association between tobacco smoking
and liver cancer as causal”.
Hypnosis to prevent Lung
cancer
Lung cancer is the most common cancer in the world with 1.2 million new
cases diagnosed every year. Until recently, lung cancer was the most frequently
occurring cancer in the UK; it has now been overtaken by breast cancer
but it still accounts for 1 in 7 new cancer cases, that is, around 38,400
new patients annually. In Britain, one person every fifteen minutes is
diagnosed with lung cancer. Lung cancer is the cancer most commonly associated
with smoking: around 90% of all lung cancers are caused by smoking, either
directly or through indirect exposure. Because of its poor prognosis,
lung cancer is still the most common cause of cancer death in the UK,
with around 33,600 deaths each year, accounting for 6% of all deaths and
22% of all cancer deaths in the UK.
One in two smokers dies prematurely: of these, nearly one in four will
die of lung cancer. The risk of dying from lung cancer increases with
the number of cigarettes smoked per day, although duration of smoking
is the strongest determinant of lung cancer in smokers. Smokers who start
when they are young are at an increased risk of developing lung cancer.
Results of a study of ex-smokers with lung cancer found that those who
started smoking before age 15 had twice as many cell mutations as those
who started after age 20.
A longitudinal study of British doctors by Doll and Peto examined the
effects of prolonged cigarette smoking and prolonged cessation on mortality
from lung cancer. They found that if people who have been smoking for
many years stop, even well into middle age, they avoid most of their subsequent
risk of lung cancer. Also, stopping smoking before middle age avoids more
than 90% of the risk attributable to smoking.
Hypnotherapy
to prevent Oesophageal cancer
Tobacco smoking is a cause of cancer of the oesophagus (gullet) and the
risk increases with the number of cigarettes smoked and duration of smoking.
The risk also remains elevated many years after smoking cessation.
Hypnosis to prevent Pancreatic cancer
Cancer of the pancreas is a rapidly fatal disease with a five year survival
rate of only 4%. Cigarette smoking is a strong and consistent predictor
of pancreatic cancer although the risk diminishes to that of a non-smoker
ten years, on average, after cessation. Risk of the disease is related
to consumption and duration of smoking. Smokers have about twice as high
a risk for this cancer as non-smokers.
Hypnosis to prevent Passive smoking
Non-smokers are at risk of contracting lung cancer from exposure to other
people's smoke. The UK's Scientific Committee on Tobacco and Health (SCOTH)
found that the research findings were consistent with an increased risk
of lung cancer in non-smokers of between 20% and 30%. A subsequent review
of the evidence by SCOTH in 2004 re-confirmed that the increased risk
was in the order of 24%. This means that passive smoking causes several
hundred lung cancer deaths in non-smokers each year in the UK. The IARC
review confirmed that “the evidence is sufficient to conclude that
involuntary smoking is a cause of lung cancer in never smokers.)
Hypnotherapy
to prevent Stomach cancer
Studies have shown a consistent association between cigarette smoking
and cancer of the stomach in both men and women. Risk increases with duration
of smoking and number of cigarettes smoked, and decreases with increasing
duration of successful quitting.
