A 20-year-old man who never smoked or drank was diagnosed with lung cancer. Reminder: Touch 5 things less, and your lungs will thank you

A 20-year-old was diagnosed with lung cancer?

Xiao Liu (pseudonym) just turned 20 years old. After graduating from high school, he went out to work to earn money to support himself. He used to work in restaurants and KTV before. This time, he found a new job to prepare for entry. During the entrance examination, he was found to have abnormal shadows in his lungs, and further examination was diagnosed as lung cancer.

This made Xiao Liu feel unacceptable. After getting the diagnosis results, he kept begging the doctor to check him again, because he did not smoke or drink, and there was nothing big on his body. Bad habits, how can I not understand that they will be equated with cancer. However, the results of the examination were already “certain”, and Xiao Liu did suffer from lung cancer.

In recent years, more and more patients are clinically non-smokers but diagnosed with lung cancer. This situation deserves everyone’s attention.

First, the new trend of lung cancer: the number of people who do not smoke clinically but get lung cancer is increasing< /h1>

Lung cancer is clinically divided into small cell lung cancer and non-small cell lung cancer, of which non-small cell lung cancer refers to all lung cancers except small cell lung cancer, including squamous cell carcinoma, adenocarcinoma, Large cell lung cancer, etc. Squamous lung cancer is the most common form of lung cancer in smokers and adenocarcinoma in non-smokers.

Professor Wu Yilong, the tenured director of Guangdong Provincial People’s Hospitalpointed out that in the 1970s and 1980s , squamous cell carcinoma and lung cancer account for 40% and 35% of all lung cancers, respectively. At present, adenocarcinoma accounts for 60%, while squamous cell carcinoma accounts for only about 20%, women suffer from adenocarcinoma The incidence rate has more than doubled.

The reason why more and more non-smokers develop lung cancer is closely related to these factors in life. To prevent the occurrence of lung cancer, it is necessary to avoid these five factors as much as possible.

Second, why some people will get lung cancer if they don’t smoke, these factors must be paid attention to

1. Air exhaust< /strong>

The rapid development of modern science and technology brings with it the atmospheric pollution caused by a large amount of industrial waste gas, gasoline combustion, coal, etc. in the environment. Long-term exposure of the human body to these substances will lead to Increased risk of cancer.

2, nutritional deficiencies

long-term lack of vitamin E, vitamin B2, vitamin E in the diet 1. People with trace elements such as zinc and selenium have an increased risk of lung cancer.

3. Exposure to carcinogens< /p>

Some people need to be exposed to carcinogens such as tar, asbestos, nickel and radioactive elements for a long time due to work, which in turn increases the risk of lung cancer.

4. Poor control of some lung diseases

self suffering from pneumoconiosis, tuberculosis, And patients with silicosis and other diseases, if there is no active treatment and intervention, the risk of developing lung cancer will be much higher than that of ordinary people. Some patients with chronic pulmonary bronchial inflammation and pulmonary fibrous scar lesions may cause squamous metaplasia and hyperplasia during the healing process. On this basis, there is also a certain risk of developing cancer.

5. Secondhand smoke

Forced secondhand smoke is also an important factor in inducing lung cancer One of the factors is that about 7,000 people die from lung cancer each year due to secondhand smoke.

There are non-smokers who suffer from lung cancer in their lives, and some who have smoked all their lives. People, but not suffering from lung cancer, the body is very healthy, why is this?

Third, why do some people smoke all their lives without getting lung cancer and live a good life?

1. Genes are powerful

A study published in Nature Genetics states, As smoking increases, so does the number of cellular mutations in the body, which increases the risk of developing cancer. But some people have powerful mechanisms in their bodies that protect them from lung cancer by restriction mutations.

2. Probability Questions

A survey in the UK shows that never smokers The risk of lung cancer in the population is very low, and some long-term smokers have a 16% risk of developing lung cancer. We can’t be sure if we are among the lucky smokers who don’t get cancer.

Plus,the amount of smoking is also an important factor in cancer risk , people who smoked <5 cigarettes a day had a 1/6 chance of developing cancer, while some people who smoked >5 cigarettes a day had a 1/4 chance of developing cancer.

There is no doubt that smoking is one of the main causes of lung cancer, but we Nor can some other possibleRisk factors that can cause lung cancer should be avoided as much as possible in life.
