Xiao Zhang's father is an old smoker who has been smoking for over forty years and is now almost seventy years old. She always makes her father quit smoking because she is worried that his father will get lung cancer as he grows older, so she begins to strictly control his smoking volume,Due to his father's heavy smoking habit, Xiao Zhang's advice was of no use, and he would secretly hide and smoke.

For the sake of her father's health, Xiao Zhang took him to the hospital for a check-up, and the results surprised her. There was no obvious problem with his lungs.After inquiring with the doctor, it was found that smoking a cigarette does not necessarily lead to lung cancer.

So, why should an old smoker who has been smoking for decades not have lung cancer instead?

Let's start by saying, what are the hazards of smoking in general?

1. Cancer:

In China, there are approximately 820000 new cases of lung cancer every year.It contains a variety of harmful chemicals known as Carcinogen, which can damage DNA and lead to uncontrolled cell growth.

Lung cancer is the most common type of cancer associated with smoking, but it is also associated with throat cancer, Oral cancer, Esophageal cancer, pancreatic cancer, bladder cancer cancer, kidney cancer and Cervical cancer.

2. Respiratory disease:

Smoking damages the respiratory system in multiple ways.The toxic chemicals in tobacco smoke can irritate the respiratory tract and cause inflammation,It causes chronic diseases such as Chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) includes two main diseases: Emphysema (involving the destruction of pulmonary air bags) and chronic bronchitis (leading to inflammation and airway stenosis).These situations can lead to breathing difficulties, coughing, wheezing, and an increased risk of respiratory infections.

3. Cardiovascular disease:

Smoking is the main risk factor for heart disease and stroke.Chemicals in tobacco smoke can damage blood vessels, leading to Atherosclerosis, that is, fat deposition and plaque accumulation in arteries.This can narrow the arteries and restrict blood flow, leading to an increased risk of blood clots, heart disease, and stroke. Smoking also increases blood pressure and causes Arteriosclerosis.

4. Decreased lung function:

Smoking can damage lung function and reduce Vital capacity.The toxic substances in cigarette smoke, such as tar and nicotine, can damage lung tissue and impair the function of the air sacs (alveoli) responsible for oxygen exchange.Over time, this can lead to a decrease in lung efficiency, making breathing more difficult and reducing physical strength.

5. Increased risk of infection:

Smoking can weaken the immune system and impair the respiratory system's defense against infection.Smokers are more vulnerable to respiratory infections, including pneumonia, bronchitis and influenza.

The harmful chemicals in tobacco smoke can numb or kill cilia,Cilia are tiny hairlike structures in the airway that help clear mucus and capture pathogens.This can damage the respiratory system's ability to resist infections, leading smokers to develop upper respiratory diseases more frequently and severely.

6. Reproductive complications:

Smoking has adverse effects on both male and female reproductive health..

7. Eye diseases:

Smoking also increases the risk of developing cataracts,.

..

However, as stated in the preface,Why do some old smokers actually not get lung cancer?

Once,Shanghai Jiao Tong University published a research paper on the relationship between smoking and lung cancer in the journal Nature Genetics,.

The study suggests that heavy smokers actually have fewer mutated genes in their bodies,The biggest possibility is that they have evolved more powerful DNA repair ability,.

According to their investigation,.

Although some long-term smokers may not develop lung cancer, it is worth noting that,.

Smoking is inherently associated with significant health risks, and. .
