Will e-cigarettes actually cause cancer?


Will not. To know, whether e-cigarettes cause cancer is not a complex problem, and the relevant scientific conclusions have long become the consensus of authoritative medical institutions and researchers around the world. In recent years, top cancer research institutions and experts have also spoken out for e-cigarettes to counter the rumors that e-cigarettes cause cancer. The currently available evidence is as follows:

Truth: The cancer rate is less than 0.5 percent of cigarette smokers

According to the World Health Organization list of carcinogens, tobacco and second-hand smoke are category 1 carcinogens (clear can be carcinogenic, a total of 120 types). Tobacco has 69 kinds of carcinogens, such as nitrosamine, formaldehyde, and polycyclic aromatic hydrocarbon benzene (A) pyrene, most of which exist in the tar and smoke produced by its combustion. By contrast, nicotine is only addictive, not even the last class 4 carcinogens.

At present, the mainstream e-cigarette products on the market mostly use electronic atomization technology, which does not contain tobacco, so it can reduce the harm of cigarettes by 95%. As for carcinogen content, data released by the US Centers for Disease Control and Prevention in July 2020 showed that e-cigarette users contain only 2.2 percent of NNAL in their urine than in smokers. NNAL is a class 1 carcinogen and a metabolite of the potent lung cancer factor nitrosamine.

As for another type of carcinogens (such as formaldehyde and acetaldehyde), Gan Wei, a genetic statistics researcher at the University of Oxford, gave a detailed answer in June 2021. He said that some e-cigarette products will contain base compounds, the content varies by product type, and different experimental environments, different conclusions, need comprehensive analysis, can not be generalized.

Taking a comparative study of 13 e-cigarette products as an example, the study showed that five e-cigarette products did not contain formaldehyde and acetaldehyde, and the average formaldehyde and acetaldehyde content in the other eight e-cigarette products were 13 times and 807 times lower than the average formaldehyde and acetaldehyde content in cigarette smoke, respectively. That is, the content of base compounds in e-cigarettes is lower than that in cigarettes.

The actual use of the user is indeed consistent with the experimental conclusion. According to a 2018 study released by the Department of Public Health in the UK, the cancer rate of e-cigarette users is only about 0.4 percent of those smokers, less than 0.5 percent."E-cigarettes have great potential to reduce harm and can effectively reduce the risk of cancer among smokers."The UK Public Health Department stressed in a report published on the UK Government website (http://GOV.UK).

Cancer researchers in many countries have encouraged smokers to switch to e-cigarettes
In recent years, the e-cigarette industry has developed rapidly, and the "huge harm reduction potential" of e-cigarettes has been continuously confirmed by the international authoritative research institutions. In April 2021, Cancer Research UK issued a document indicating that e-cigarettes have become a broad consensus among public health institutions and researchers worldwide, and the popularization of e-cigarettes can effectively reduce the cancer rate of smoking.

Scientists are still studying the potential health hazards of the long-term use of e-cigarettes, but what is important is that the amount of carcinogens found in electronic cigarette aerosols is far lower than that found in cigarette smoke."The American Cancer Society (ACS) website says. In addition, studies in the United States have shown that cancer smokers switching to e-cigarettes can reduce the negative effects of smoking on chemotherapy.
As the world's top cancer doctor, David Khayat has undoubtedly seen and endorsed this scientific evidence. The former president of the British National Cancer Institute has changed the way of cancer research and cancer patients (CBE).
This time, in her health advice for people aged 35-50, the David Khayat specifically stressed that smokers should consider switching to e-cigarettes: " The key to living a happy life is understanding and managing risks. Only small steps can improve your health.

However, Cancer Research UK notes that many smokers will mix cigarettes and e-cigarettes before completely switching to e-cigarettes, which does not reduce the harm. Therefore, cancer RC need to further explore factors affecting smokers' choices and find effective ways to help smokers switch to e-cigarettes.
"Most of the adverse effects of smoking will take decades to manifest."It took us several generations of research to draw the scientific conclusion that smoking is harmful to health," Gan said. " Regarding the long-term impact of e-cigarettes on the human body, with both positive and negative conclusions, we need to follow the development of the industry and continue to strengthen relevant research.

I hope everyone can treat e-cigarettes rationally.
