Smoking is the direct cause of lung cancer!

Smoking is the direct cause of lung cancer! We all know that smoking is harmful to the human body, but many people continue to smoke. Experts have found through investigations on the causes of lung cancer that smoking is one of the causes of lung cancer and accounts for a large proportion of lung cancer patients. So why is smoking the direct cause of lung cancer? Let me tell you through some investigations and data.

Smoking is the direct cause of lung cancer:

1. Some women who live with smokers have a 6 times higher risk of lung cancer than normal people.

2. The incidence of lung cancer in long-term smokers is 10 to 20 times higher than that in non-smokers, the incidence of laryngeal cancer is 6 to 10 times higher, the incidence of pancreatic cancer is 2 to 3 times higher, the incidence of bladder cancer is 3 times higher, the incidence of esophageal cancer is 4 to 10 times higher, and the risk of blood cancer increases by 1.78 times.

3. If you smoke more than 25 cigarettes a day, 12% of people will develop lung cancer.

4. 30% of cancers can be attributed to smoking, especially lung cancer, laryngeal cancer, oral cancer, esophageal cancer, bladder cancer, pancreatic cancer and kidney cancer. The most deadly are lung cancer and pancreatic cancer.

5. A hospital found that 80% of the 1,000 lung cancer patients were long-term smokers. Female smokers are at a higher risk, 1.9 times that of male smokers.

6. A smoking index (number of years of smoking × average number of cigarettes smoked per day) exceeding 400 is a dangerous signal. For example, a young man who started smoking at the age of 15 and smoked a pack a day may get lung cancer before the age of 35 to 40.

7. In most countries around the world, 90% of lung cancer is caused by smoking. In my country, 35 people out of every 100,000 people suffer from lung cancer. The earlier the age of smoking, the higher the incidence and mortality of lung cancer. If the lung cancer mortality rate of non-smokers is set as 1.00, the mortality rate of smokers who start smoking under the age of 15 is 19.65, 10.08 for those aged 20 to 24, and 4.08 for those aged 25 and above.

8. Women who smoke have a higher relative risk of cervical cancer and ovarian cancer. The former is 4.4 times higher than that of non-smokers, and the latter is 2.8 times higher. The relative risk of cervical cancer in families exposed to passive smoking is 2.5 times higher than that of non-passive smoking.

9. Women who smoke for more than 20 years have a 30% increased risk of breast cancer, and those who smoke for more than 30 years have a 60% increased risk. Smokers develop cancer 8 years earlier than non-smokers.

10. Smokers undergo beneficial changes after quitting smoking. Within 5 years, the lung cancer mortality rate is lower than that of ordinary smokers (one pack per day) or close to that of non-smokers. The incidence of oral, respiratory, and esophageal cancers is reduced to half of that of smokers. Within 10 years, precancerous cells are replaced by healthy cells. The incidence of lung cancer in people who quit smoking for more than 10 years is roughly the same as that of non-smokers.

Through the above introduction, I believe that everyone is convinced that smoking is the direct cause of lung cancer. Relevant experts also pointed out that as long as you stop smoking, 90% of lung cancer can be prevented. Lung cancer patients who continue to smoke will increase the difficulty of treatment and complications, while stopping smoking can prolong survival and reduce the recurrence rate of lung cancer. It can be seen that smoking is very harmful to the human body. I hope that everyone can smoke less or not smoke at all. Maintaining a healthy body is the most important thing.
