Incidence of cancer

I. Diseases related to smoking/cancer mainly include:

1. Cardiovascular diseases: Smoking is related to coronary heart disease, hypertension, sudden death and thromboangiitis obliterans. Smoking can promote thrombosis and reduce the sensitivity of human body to the precursors of heart disease.

2. Respiratory diseases: chronic bronchitis, emphysema, chronic obstructive pulmonary disease and lung cancer.

3. Diseases of digestive system: peptic ulcer, gastritis, esophageal cancer, colonic lesions, pancreatic cancer and gastric cancer.

4. Cerebrovascular diseases: Smoking will increase the risk of cerebral hemorrhage, cerebral infarction and subarachnoid hemorrhage. In addition, smoking can also damage brain cells, memory, thinking ability and lead to mental disorders.

5. Endocrine diseases: Smoking 20 cigarettes a day can increase the risk of diabetes by 1 fold. Smoking can also promote thyroid diseases.

6. Oral diseases: such as lip cancer, oral cancer, oral leukoplakia, candida albicans infection, oral mucosal pigmentation, oral odor, etc.

7. Ophthalmic diseases mainly include toxic optic neuropathy, decreased visual adaptability, macular degeneration and cataract.

Second, the harm to teenagers

Smoking is more harmful to teenagers. According to medical research, teenagers are in a period of growth and development, and their physiological systems and organs are not yet mature. Their resistance to harmful factors in the external environment is weaker than that of adults, and they are easy to absorb poisons and damage the normal growth of their bodies. According to a survey of 25 states in the United States, the age of starting smoking is negatively correlated with the mortality rate of lung cancer. If the mortality rate of lung cancer in non-smokers is 1.00, the mortality rate of smokers under 15 is19.68; 20-24 years old is10.08; 4.08 for those over 25 years old. It shows that the earlier you start smoking, the higher the incidence and mortality of lung cancer.

Smoking damages the brain, dulls thinking, reduces memory, affects study and work, and reduces students' academic performance. Psychological research shows that the intelligence efficiency of smokers is lower than that of non-smokers 10.6%.

Third, the influence of smoking on pregnant women and fetuses.

Smoking damages almost all important organs of human body: respiratory system, circulatory system, nervous system, urinary system and other important organs, which is the same for men and women. However, the special physical structure of women and the physiological characteristics of giving birth to the next generation will cause some special harm to smoking women and their fetuses.

First of all, smoking will reduce the fertility rate of both husband and wife. A follow-up study of 17000 women of childbearing age in the UK for 1 1 year shows that smoking will reduce the fertility rate. The infertility rate of women who smoke more than 10 cigarettes a day is 10.7%, while the infertility rate of women who don't smoke is only 5.4%. Another survey also believes that the risk of infertility among smoking women is 2.7 times that of non-smoking women; If both husband and wife smoke, the possibility of infertility is 5.3 times higher than that of non-smoking couples. The new experimental results show that nicotine in tobacco has an influence on sperm shape, exercise ability, straight swimming ability and sperm penetration ability, and the higher the nicotine concentration, the greater the influence. A British research report found that the sperm concentration and the percentage of active sperm in the smoking group were significantly lower than those in the non-smoking group. The average sperm content in the semen of the smoking group is 25 million/ml, and that of the non-smoking group is 63 million/ml. Only 49% of the sperm in the smoking group, while more than 63% in the non-smoking group. Therefore, smoking is one of the important causes of male infertility.

Smoking in pregnant women is very harmful to the development and health of the fetus. Tobacco contains a lot of toxic substances, besides nicotine, there are hydrocyanic acid, ammonia, carbon monoxide, carbon dioxide, pyridine, aromatic compounds and tar. These toxic substances can be absorbed into maternal blood with smoke, thus reducing the oxygen content in maternal body and placenta. Due to lack of oxygen, the growth and development of the fetus may be delayed, so the low birth weight babies born to pregnant women who smoke are twice as many as those born to pregnant women who don't smoke. These babies are not only weak, but also have a high risk of serious diseases and a high mortality rate within one year after birth. In recent years, many studies have also shown that pregnant women who smoke are more likely to have miscarriage, premature delivery and stillbirth than pregnant women who don't smoke. The survey also found that smoking during pregnancy will damage the fertility of daughters in adulthood.

Smoking in pregnant women will increase the incidence of fetal congenital malformation. Statistics show that the number of congenital malformations born to smoking mothers is 2.3 times that of non-smoking mothers. Smoking causes fetal malformations such as anencephaly, cleft palate, cleft lip, dementia and physical development disorders, which is 2.5 times that of non-smokers.

The research results of foreign countries in recent two years show that pregnant women's exposure to nicotine and other chemicals in cigarettes will seriously affect the transmission of nerve cells and sound waves in the cochlea to inner ear neurons, so pregnant women's smoking will lead to fetal hearing loss. A study in the United States also found that babies born to pregnant women who smoke have abnormal hearing. According to the follow-up survey, when the children reach 6_ 12 years old, they are given a hearing test according to their mothers' smoking during pregnancy. The results show that the more pregnant women smoke, the worse their children's hearing response. Children who smoke secondhand smoke have found similar results.

A large-scale survey conducted by Danish researchers confirmed that 30% to 40% of sudden death babies are related to mothers smoking during pregnancy, and the risk of sudden death of babies born to women who smoke during pregnancy is three times higher than that of babies born to non-smoking women. The researchers pointed out that nicotine in cigarettes may be the culprit, because nicotine has the function of weakening or destroying the fetal self-protection mechanism.

Another survey showed that the incidence of congenital heart disease in infants born to smokers was 7.3%, while that of infants born to non-smokers was 4.7%. A study in Germany found that smoking in pregnant women is more harmful to the fetus than is currently recognized. If you smoke 10 cigarettes every day during pregnancy, the risk of fetal cancer will increase by 50% and the possibility of leukemia will double. Researchers found typical NNAL carcinogens produced by tobacco in the urine of female newborns who smoked. The fetus absorbs nicotine through umbilical cord, converts it into NNAL in the liver, and finally excretes it through the kidney. In this way, pregnant women who smoke will cause damage to the liver, kidneys and lungs of the fetus.

In addition to the above indirect effects on the fetus, smoking in pregnant women will also have a direct impact on the fetus. Smoking can accelerate fetal heart rate and reduce respiratory movement. Nicotine and other toxic substances in smoke can also penetrate into the placenta through blood, be transported to the fetus and even cause damage to imperfect organs.

Smoking in pregnant women is not only harmful to the fetus, but also harmful to their own health. It is reported that pregnant women who smoke will have complications such as placental abruption, bleeding and premature water breakthrough during delivery, which is 1-2 times higher than that of normal women.

Therefore, for the health of the next generation and pregnant women themselves, pregnant women should stay away from cigarettes, avoid passive smoking, and spend their pregnancy and delivery in a fresh and pleasant environment.

Fourth, the harm to women.

Smoking and ectopic pregnancy.

In the past 20 years, the incidence of ectopic pregnancy (mainly tubal pregnancy) among women all over the world has increased by two or three times. In the past, it was thought that the main causes of ectopic pregnancy were pelvic inflammatory disease and sexually transmitted diseases. However, why is ectopic pregnancy still on the rise in areas where the incidence of pelvic inflammatory disease and sexually transmitted diseases is decreasing? Experts have been looking for new risk factors of ectopic pregnancy, one of which is smoking. Experts have found that no matter how the history of sexual life, pelvic infection, birth control and childbirth changes, the occurrence of ectopic pregnancy is obviously related to the amount of smoke inhaled by pregnant women. The researchers divided pregnant women into two groups. The incidence of ectopic pregnancy in smoking group was 40. 1%, while that in non-smoking group was 29.7%. There is a significant difference between the two groups. A research team from the University of Washington conducted a case-control study on 274 patients with ectopic pregnancy and 727 pregnant women in the same period, and concluded that the risk of tubal pregnancy among smokers was 40% higher than that of non-smokers.

The study on the causes of ectopic pregnancy caused by smoking in pregnant women found that smoke can stimulate and thicken the walls of small blood vessels, so the blood circulation in pelvic cavity changes, which leads to a series of changes such as fertilized eggs implantation variation. Some people think that nicotine destroys the microfilament structure of fallopian tube that sends eggs to uterus, so that fertilized eggs can not be transported to uterus normally. Therefore, the slogan "If you are pregnant, please quit smoking immediately" was put forward in the United States. Pregnant women should not only smoke, but also avoid going to places with more smoke.

2. Smoking and infertility

The fertilization rate of female eggs who smoke is greatly weakened. Compared with non-smoking women, the risk of infertility of smoking women is 2.7 times that of non-smoking women. American researchers found that the fertility of smokers is 72% lower than that of non-smokers. British researchers found that Ding Ning, the decomposition product of nicotine, had a significant effect on the pregnancy of 45 infertile women undergoing in vitro fertilization. Researchers believe that Ding Ning can affect the production of estrogen in women's reproductive cycle, but compared with women without this substance, the proportion of female fertilized eggs taking Ding Ning has decreased by 60%. If the husband smokes, the situation is even worse. Statistics show that smoking couples are 5.3 times more likely to be infertile than non-smoking couples.

3. Smoking and dysmenorrhea

Many smokers say that smoking makes people feel "relaxed", "relieved of tension" and makes them "feel good". However, a study by the University of Milan in Italy shows that this temporary "relaxation" can cause dysmenorrhea, which is what women call fatal stomachache. Doctors observed 25 1 women aged 15-44. During the follow-up of 18 months, it was found that compared with non-smokers, women who smoked 10-30 cigarettes a day had twice the risk of dysmenorrhea except fibroadenoma, ovarian cyst and endometriosis. Women who smoke for more than 20 years are almost three times more likely to suffer from dysmenorrhea than non-smokers. The reason is that smoking constricts blood vessels, narrows them and slows down blood flow. According to expert analysis, this may partly explain the cause of dysmenorrhea, that is, smoking will also reduce the blood flow of endometrium, which will lead to painful spasm.

Smoking will accelerate menopause.

According to the report of American Medical Tribune 1994, a study shows that women who started smoking before 17 years old or smoked every day for 20 years will be 2 to 3 times more likely to have menopause before 40 years old. The researchers selected 344 natural menopausal women before the age of 47 and 344 age-matched women who were still menstruating or menopausal after the age of 47 as the control group. The results showed that compared with the non-smoking control group, the menopause rate of women who smoked between the ages of 45 and 54 increased by 43%. It is worth noting that smoking is a risk factor for ovarian failure at any age. Smoking is not only related to ovarian failure at the age of 40, but also a risk factor at the age of 25 to 30. Why does smoking lead to early menopause? Studies have shown that some components in smoke are toxic to follicles, leading to premature disappearance of follicles. Or due to estrogen deficiency. Smoking leads to menopause about 0-3 years earlier.

5. Female smoking can lead to osteoporosis.

A study of 465,438+0 pairs of twin sisters by doctors at the University of Melbourne, Australia, confirmed that women who smoke have more fragile bones and are more prone to fracture in old age. 4 1 Twin sisters (smokers and non-smokers) aged between 23 and 73 were matched, and the bone mineral density of their lumbar vertebrae, femoral neck and femoral shaft was measured. For women who continue to smoke as adults, the average bone mass index of smokers is 5%- 10% lower than that of non-smokers. Bone mineral density was measured every 10 year. Compared with non-smokers, the BMD of lumbar spine, femoral neck and femoral shaft decreased by 2%, 1.4% respectively. Studies have shown that every decrease in bone density 10% will reduce bone strength by 30%. As long as the bone mineral density decreases within 10 years 10%, the incidence of femoral neck fracture will increase by 44%. It is estimated in the United States that about 250,000 people are hospitalized for femoral neck fractures caused by osteoporosis every year, and the number of women is 6-8 times that of men. About 50,000 people die every year, which is the same as that of breast cancer.

A study by Harvard Medical School in the United States shows that if women still smoke after menopause, the protective effect of estrogen therapy may be reduced. He said: "Women who smoke and take estrogen have the same risk of hip fracture as women who don't take estrogen."

6. Women who smoke can cause urinary incontinence.

A study in 1992 showed that the risk of urinary incontinence of smoking women increased by 1.5 times, while that of quitting smoking women increased by 1.2 times. The researchers observed 322 middle-aged women with urinary incontinence and 284 women of the same age without urinary incontinence. Compared with women without urinary incontinence, most women with urinary incontinence are smokers or former smokers. The more you smoke, the greater the possibility of urinary incontinence. The total risk of bladder control problems among smokers and former smokers increased by 28%.

Cough may be an important cause of urinary incontinence in smokers. Cough is severe enough to cause physical damage to the muscles that control the flow of urine. Animal experiments have proved that nicotine can damage bladder muscles that control urine flow through its toxins. Of course, aging and childbearing will weaken and sag the structures that support the bladder, such as the pelvic floor, leading to urinary incontinence.

7. Smoking will reduce breast milk secretion.

American researchers have found that another harmful effect of smoking on infants is to reduce the quantity and quality of breast milk secretion. According to the researcher's research, the milk yield of smoking women two weeks after delivery is 2 1% less than that of non-smoking women. The secretion decreased by 43% at 4 weeks after delivery, but the difference was 46% at 6 weeks after delivery. The fat content in milk of smoking women is less than that of non-smoking women 19%. If the mother stops smoking, her milk secretion will increase, which means that the adverse effects of smoking will weaken or disappear after quitting smoking. Its mechanism remains to be studied.

8. Women who smoke and take birth control pills are prone to heart disease.

Women who smoke and take birth control pills will significantly increase the risk of cardiovascular diseases such as myocardial infarction. A recent study in the United States investigated 5779 women aged 18_44, and found that 7.4% of them both smoked and took birth control pills, and 1. 1% of them smoked more than 20 cigarettes a day. Research and analysis show that the incidence of acute myocardial infarction in women who smoke and take contraceptives is 200% higher than that in the general population.

American researchers studied more than 2,000 women and found that women who smoked more than 25 cigarettes a day and used oral contraceptives suffered the most, and their risk of myocardial infarction was 13 times that of non-smoking women. Studies have shown that smoking and birth control pills increase the possibility of blood clots. Japanese research reports that the mortality rate of myocardial infarction caused by smoking and taking oral contraceptives is 1 1.7 times higher than that of non-smokers. The older you get, the longer you smoke, and the higher your mortality rate. Therefore, the US Food and Drug Administration pointed out in the instructions of oral contraceptives that smoking is not allowed.

9. Women

Smoking will accelerate aging.

As early as 1928, Dr. Bohr of Hopkins Medical College put forward the theory that hypoxia would accelerate aging for the first time while studying cell biology. Smoking leads to long-term hypoxia and decreased estrogen secretion, which leads to premature aging. American scholars divide some smoking women of similar age into four groups according to the length of smoking time and the amount of smoking. The results show that those who smoke for a long time and heavily enter menopause ahead of time, their lips and eyes wrinkle prematurely, their teeth turn yellow, their skin is rough, they lose their elasticity and plump appearance, and some signs of aging appear prematurely.

Smoking and gynecological tumors.

The report "The Relationship between Smoking and Gynecological Tumors" published by the Department of Obstetrics and Gynecology of Beijing Medical University shows that 27 1 patient has been diagnosed with various gynecological malignant tumors through retrospective investigation, and compared with 375 age-matched non-gynecological cancer patients and normal women, it is found that the relative risk of cervical cancer and ovarian cancer in smoking women is higher than that in non-smoking women, with the former being 4.4 and the latter being 2.8. The relative risk of cervical cancer among passive smokers in the family is 2.5 times that of non-passive smokers. It is reported that the contents of nicotine and its metabolite Ding Ning in serum, urine and vaginal secretions of smokers are higher than those of non-smokers. But Ding Ning also increased in the serum of passive smokers.

Breast cancer: A survey of 3,240 women undergoing mammography in Denmark found that the risk of breast cancer increased by 30% for women who smoked for more than 20 years, and by 60% for women who smoked for more than 30 years. The onset time of cancer in smokers is 8 years earlier than that in non-smokers. The American Cancer Research Center believes that the rising incidence of female breast cancer in recent years is closely related to the environmental factor of smoking, and smoking is the primary cause of breast cancer in most women. They conducted a six-year follow-up survey of more than 600,000 women. The results showed that the mortality rate of women who smoked was 25% higher than that of women who did not smoke, and the more they smoked, the longer they smoked, and the greater the risk of women dying from breast cancer.

Cervical cancer: A 9-year follow-up survey of 6,000 women published in Norway shows that the probability of cervical cancer or malignant tumor among women who smoke is 50% higher than that of non-smokers, especially among women who smoke 15 cigarettes a day and smoke for more than 10 years, the probability of cervical cancer is more than 80% higher than that of non-smokers. The long-term accumulation of nicotine in cervical cells is the main factor leading to canceration. The report also found that if a woman's husband or boyfriend smokes, the probability of cervical cancer among women who live with her every day is 40% higher than that of women whose spouses don't smoke.

British medical experts point out that women who have frequent sexual life and smoke are twice as likely to develop and die of cervical cancer as women who don't smoke. The uterus of smokers lacks Langerhans cells (Langerhans? Cells), when the human body is threatened by viruses or chemical products, such cells can enhance the function of its immune system. If you smoke more, there will be fewer such cells, and the number of smoking women is less than that of non-smoking women 1/3. They believe that hpv virus is the main cause of cervical cancer. When infected with hpv virus, the lack of Langerhans cells will reduce immune function and lead to cancer. In Britain, 2000 women die of cervical cancer every year. Some experts say that smoking can lead to "small AIDS" in the uterus.

As early as 1984, an investigation was made in the United States. The risk of cervical cancer in smoking women is 3.4 times that of non-smoking women. The study also found that women who smoke passively for 3 hours (or more) a day have three times the risk of cervical cancer as women who do not live in a smoking environment.

Ovarian cyst: According to the report of American Medical Tribune 1994, smoking doubles the risk of developing functional ovarian cyst in women. The authors observed 98 patients, aged 1539 years, who were newly diagnosed as functional ovarian cysts. These cases do not include pregnant women, women who have given birth for 3 months, women who have received infertility drugs or women who have been diagnosed with polycystic ovary disease, cystic teratoma, endometrial tumor, cystic adenoma and cystic adenocarcinoma. 239 women served as control group. After controlling the interference factors such as weight, postpartum status, abortion history, ovarian cyst history and current oral contraceptives, the risk of smoking women is twice that of the control group. Experimental research shows that smoking has anti-estrogen effect, which can not only reduce endogenous estrogen production, but also change estrogen metabolism of premenopausal women.

1 1. Smoking is harmful to the health of elderly women.

A study in the United States shows that compared with non-smokers and quitters, women who smoke over 65 are worse in 65,438+02 physical indicators, such as muscle strength, agility, coordination, gait, thinking, reaction, living ability and balance. Those who smoke 65,438+02 cigarettes a day are worse on almost every index. Smoking is also a risk factor for arteriosclerosis, especially arteriosclerosis of lower limbs. Smoking for many years will affect walking and motor function. Research also shows that the elderly can improve their health after quitting smoking.

The benefits of quitting smoking

I. Overview

According to scientists' experiments for many years, a series of beneficial changes will take place in the internal organs of smokers after quitting smoking, which are roughly as follows:

Within 20 minutes: blood pressure drops to the standard level; Pulse drops to standard speed; The temperature of hands and feet rose to standard body temperature.

Within 8 hours: the content of carbon monoxide in blood drops to normal level; The oxygen content in the blood increased to normal level.

Within 24 hours: the risk of myocardial infarction is reduced.

Within 48 hours: the function of nerve endings gradually began to recover; Smell and taste are more sensitive to foreign substances.

Within 72 hours: no more bronchospasm, greatly relaxed breathing and increased vital capacity.

2 weeks 1 month; Stable blood circulation; Steady and light; Lung function improved by 30%.

1 to 9 months: symptoms such as cough, sinus congestion, fatigue and shortness of breath are relieved; New cilia appear on trachea and bronchial mucosa, and the function of handling mucus is enhanced; Less sputum, cleaner lungs and less chance of infection; Improve the body's energy reserve; The weight can be increased by 2 _ 3kg.

1 year: the risk of coronary atherosclerosis is reduced to half of that of smokers.

Within five years: the mortality rate of lung cancer is lower than that of ordinary smokers (one pack a day), that is, from 1.37% to 0.72%, or close to that of non-smokers; The incidence of oral cavity, respiratory tract and esophageal cancer dropped to half of that of smokers; The incidence of myocardial infarction is almost reduced to the level of non-smokers.

10 years: precancerous cells were replaced by healthy cells, and the incidence of lung cancer dropped to the level of non-smokers; The incidence of cancer in oral cavity, respiratory tract, esophagus, bladder, kidney and pancreas decreased significantly.

Within 15 years: the risk of coronary atherosclerosis is the same as that of non-smokers.

Therefore, it is never too late to quit smoking, and it is best to quit smoking before your health is seriously damaged. A cohort study of British doctors shows that if smokers can quit smoking before the age of 35, the risk of dying from tobacco-related diseases is significantly reduced, which is almost similar to that of non-smokers.

Second, the changes in the incidence of major organs after quitting smoking.

1, respiratory system: the relative risk of lung cancer of smokers is 10- 15 times that of non-smokers, and the risk of lung cancer of smokers will be 30%-50% of that of continuous smokers after quitting smoking 10 years. Quitting smoking can also reduce the risk of pneumonia and bronchitis. Smoking is the main cause of chronic obstructive pulmonary disease (COPD). After quitting smoking, the rate of lung function decline with age will be close to that of non-smokers.

2, circulatory system: the risk of smokers dying of coronary heart disease is twice that of never smokers. Within one year after smokers quit smoking, this risk will be reduced by 50%. After quitting smoking 15 years, the risk will be close to that of never smokers.

3. Nervous system: Compared with non-smokers, the relative risk of death from stroke is twice that of non-smokers. Some smokers can reduce this risk to the level of non-smokers within five years after quitting smoking, while others need to stick to 15 years to get this effect. In addition, quitting smoking can improve cerebral blood flow.

4. Pregnant women smoking makes the fetal and infant mortality rate 25_50% higher than that of normal non-smokers, and the average weight of infants at birth is 200 grams lower than the normal value. If they can quit smoking before pregnancy, their babies will weigh almost the same as those born to mothers who never smoke.

Some people worry that they will get fat, but a large number of studies show that the average weight gain of smokers is only 2.3 kilograms. This weight gain has little effect on health. Of course, very few people gain more weight (more than 9 kilograms) after quitting smoking, but the possibility of quitting smoking is only 4%.

Third, China studies.

There is a common misunderstanding among middle-aged and elderly smokers in China: people who have long-term smoking habits suddenly quit smoking, which will not pay for it, and even promote death. An elderly cohort study in Xi 'an showed that after adjusting for important death risk factors such as age, blood pressure, blood lipid and weight, the total death risk of people who successfully quit smoking for two years or more was reduced by 56%. The mortality rate of coronary heart disease decreased by 93%. It is worth noting that the risk of COPD death among smokers is still high (RR=4. 10). It is suggested that the overall health protection effect of middle-aged and elderly people quitting smoking is positive. For individual diseases (such as chronic obstructive pulmonary disease), it is necessary to quit smoking as soon as possible or for a long time because of the particularity of its natural course. However, such former smokers often quit smoking because of illness, and most of the recent deaths after quitting smoking are related to the serious condition.
