On an ordinary autumn afternoon, the sky is like a palette of dark blue and light gray, and Uncle Lee, 69, has died of lung cancer.
Uncle Lee had never smoked in his life, and his death left both doctors and his family baffled and regretted. In Uncle Lee's medical record, an experienced doctor annotated a sentence: "The onset of lung cancer is not caused by a single factor. ”
Uncle Lee's career was that of an ordinary librarian, and his life was simple and regular, sorting and borrowing books in the library for decades. The air in the library always seemed to smell of ink and paper, and Uncle Li always smiled and told the children that the smell of books is the best perfume.
However, Uncle Lee's health problems seem to have been creeping up since a decade ago. That's when he started noticing that he occasionally had shortness of breath, and he thought it was just a common symptom of older people, so he didn't pay much attention to it. It wasn't until five years ago that his symptoms began to become more frequent and severe, and he went to the hospital for a detailed examination, which resulted in a diagnosis of lung cancer.
The doctors investigated Uncle Lee's lifestyle and work environment and finally concluded that Uncle Lee's lung cancer was related to two main factors. The first is the long-term working environment in the stack.
Although seemingly harmless, the books in the library produce large amounts of paper dust and mold as they age, and these tiny particles are inhaled into the lungs for a long time, causing lasting microscopic damage to the lungs.
Secondly, although Uncle Lee never smoked, he lived in a city with high air pollution for a long time. Airborne particulate matter such as PM2.5 can penetrate deep into the lungs, and long-term exposure to this environment greatly increases the risk of lung disease even if you don't smoke.
In the city where Uncle Li lives, the air quality has been rated as poor for several consecutive years, and the average annual concentration of PM2.5 has exceeded the standard all year round, several times higher than the national safety standard.
The doctor specifically mentioned in the medical record that the formation of lung cancer is a complex process, which is related to multiple factors such as genetics, environment, and lifestyle.
In Uncle Lee's case, although there is no direct history of smoking, long-term environmental effects and occupational exposures cannot be ignored.
Friends and colleagues were saddened by Uncle Lee's loss, and they recalled that Uncle Lee was always able to find everyone in need, whether it was to find a hard-to-find book or simply listen to their troubles.
Uncle Lee's life is full of love for books, but perhaps he never realizes that this love also carries an unbearable weight in his life. At the end of his life, Uncle Lee was still worried about how the old books in the library could be better preserved.
Uncle Lee's life can be said to be accompanied by books, but who would have thought that it was the dust and mold between these books that silently eroded his lungs.
In Uncle Lee's case, in addition to paper dust and mold from the library, air pollution in the city was also one of the main culprits.
In today's society, people often discuss the harm caused by vehicle exhaust and industrial emissions, but often ignore the potential threats in the daily life environment. For example, volatile organic compounds (VOCs) in household products, such as paints and detergents, can also be a factor in triggering respiratory diseases.
Some people with lung cancer have never smoked. This means that, in addition to smoking, there are many other factors that can contribute to the development of lung cancer. This shows that we should not only focus on the obvious dangers, but also on the "invisible killers".
Although he eats a relatively healthy diet, the fast pace of city life, frequent eating out, and other factors may have caused him to inadvertently consume too many processed foods and preservatives, which accumulate in the body and may also increase the risk of chronic diseases.
Uncle Lee's experience has drawn attention to non-smoking lung cancer. Through his example, people are also beginning to realize that protecting their lungs is not as simple as avoiding smoking.
