The people should know that smoking sends the risk which develops cancer to have in a big way, stops smoking regarding reduces contracts cancer's risk is how effective. This should become the general knowledge. This article is not telling the people to need to make anything, is only tells them to know anything. Smoking is the carcinogenic important hazard factor
The related research so far believed that smoking and cancer's relations mainly have the following 10 facts.
1.30% cancers may turn over to investigate in smoking, specially lung cancer, throat cancer, oral cancer, carcinoma oesophagi, but may also send the carcinoma of urinary bladder, the cancer of the pancreas and the kidney cancer. What is most fatal is the lung cancer and the cancer of the pancreas.
2. the long-term smoker compares smoker's lung cancer disease incidence rate high 10~20 times, throat cancer disease incidence rate high 6~10 times, cancer of the pancreas high 2~3 times, carcinoma of urinary bladder high 3 times, carcinoma oesophagi high 4~10 times, leukemia risk does not increase l.78 time.
3. if smokes every day above 25, 12% people will have the lung cancer.
4. some female who lives together with the smoker, its trouble lung cancer's probability must be higher than 6 times compared to the average man.
5. Jiangsu Province Tumour hospital in the admitting 1000 example lung cancer patient, discovered that 80% are the long-term smoker. The feminine smoker risk is more serious, is masculine smoker's 1.9 times.
6. the smoking index (smoking year number * smokes count to surpass 400 is a danger signal every day equally). If a young fellow, 15 years old start to smoke, every day attracts a package, to 35~40 years old, possibly the lung cancer.
7. in the world majority of countries 90% lung cancer are cause by smoking, in our country every 100,000 people have 35 people to contract the lung cancer. Smoking starts the age more early, the lung cancer formation rate and the mortality rate are higher. If the smoker lung cancer mortality rate will not suppose will be time 1.00, below 15 years old starts smoker its mortality rate is 19.65,20~24 years old is above 10.08,25 years old is 4.08.
8. the smoking woman contracts cervical cancer and the ovarian cancer relative risk factor is high. The former does not compare smoker high 4.4 times, the latter high 2.8 times. In the family the passive smoking has cervical cancer's relative risk factor high 2.5 times compared to not passive smoker.
9. smokes 20 year above woman to contract the breast cancer the risk to increase 30%, smokes above for 30 years this danger to increase 60%. The smoker cancer morbidity compares the smoker not to early 8 years.
10. smoker after no-smoking has the beneficial change, in 5 years (a package the lung cancer mortality rate drop every day) compared to the common smoker or nearly in not the smoker. The oral cavity, the respiratory tract, carcinoma oesophagi formation rate falls to smoker disease incidence rate half. in 10 years, the cancer pre-cell is replaced by the health cell. Stops smoking above for 10 years the lung cancer formation rate to fall approximately to and the smoker is not same.
The no-smoking is very advantageous to cancer's prevention
The authoritative scholar pointed out: Smoking is causes the lung cancer the primary cause, so long as stop smoking, 90% lung cancer may prevent. The lung cancer patient continues to smoke can increase the treatment difficulty and the complication, but stops smoking being able to lengthen the lifetime, and reduces the lung cancer the recurrence rate.
The tobacco is cancer independent may prevent the factor most greatly, if smokes drops year by year, then certain years later, cancer will be specially the lung cancer formation rate and the mortality rate along with it drop.
