There are a lot of people suffering from the fear of cancer caused by smoking, traditional cigarettes have become synonymous with “unhealthy”, heavy smoking poisoning people suffering from cancer cases abound. With the development of the times, electronic cigarettes into the public eye, wearing a “high-tech”, “fragrant” coat, so that people can not distinguish whether the electronic cigarette will cause cancer. Then with the author’s vision to clarify this important issue.

The main components of cigarette cancer

Cigarettes are carcinogenic mainly because tobacco releases thousands of chemicals during the combustion process, of which at least 69 are recognized as carcinogens by the International Agency for Research on Cancer (IARC) of the World Health Organization. These carcinogens cause damage to human cells through a variety of mechanisms, ultimately leading to the development of cancer. The following are the main reasons why cigarettes cause cancer:

Cigarette smoke contains more than 7,000 chemicals, hundreds of which are harmful to humans and at least 69 of which are carcinogenic. The major carcinogens include:

1.Nicotine: Although nicotine itself is not directly carcinogenic, it is a highly addictive substance that causes smokers to be exposed to other carcinogens over time.

2.Tar (Tar): Tar is a brown sticky substance produced by burning tobacco and contains a variety of strong carcinogens such as benzo[a]pyrene, benzo[a]anthracene, and other polycyclic aromatic hydrocarbons (PAHs).

3.Carbon Monoxide (CO): Carbon Monoxide reduces the oxygen-carrying capacity of the blood, leading to tissue hypoxia, and long-term inhalation increases the risk of cardiovascular disease and cancer·

4.Heavy Metals: such as cadmium (Cadmium), arsenic (Arsenic), lead (Lead), nickel (Nickel), etc. These heavy metals are carcinogenic, and long-term inhalation will damage multiple organs in the human body.

Formaldehyde (Formaldehyde) and benzene (Benzene): these substances can damage DNA and induce cell cancer.

Carcinogenic Mechanisms

Carcinogenic substances in cigarettes lead to cancer through the following mechanisms:

1.DNA damage and mutation: carcinogenic substances such as benzo(a)pyrene, nitrosamines and so on can directly damage cellular DNA, leading to gene mutation, causing cells to lose the normal growth regulation, and then become cancerous.

2.Immunity decline: long-term smoking will weaken the human immune system and reduce the body’s resistance to other carcinogens, making it easier for smokers to develop cancer.

3.Gene Mutation and Repair Disorders: Certain components in cigarettes interfere with the body’s DNA repair mechanism, leading to the accumulation of gene mutations and increasing the risk of cancer.

4.Chronic Inflammation and Cell Proliferation: Harmful substances in cigarette smoke can cause chronic inflammation in the respiratory tract and lungs, and long-term inflammatory stimulation can promote abnormal cell proliferation and increase the risk of cancer.

Cancer risk of vaping

Smoking is harmful to health is something that all people know, but some people are just addicted to cigarettes, just can’t quit smoking, so the birth of the cigarette alternative – electronic cigarettes. Currently on the market electronic cigarettes are basically divided into two ways: one is the real smoke, that is, the electric baking tobacco, although not lit, but the same very stinky! The other is analog cigarettes, in which cigarette bombs are manipulated through certain techniques to form smoke and produce the sensation of smoking.

However, vaping are really as “harmless” as people think? Not really!

vaping are not really harmless, this is just a kind of self-deception, strictly speaking, electronic cigarettes are only reduced in some of the harmful components of real cigarettes, not completely harmless. It’s true that vaping have less tar in them than real cigarettes, but the nicotine is still there (although there are nicotine-free vape oils available, but they are not popular).

There has been a lot of discussion about nicotine for many years now, and it is the main culprit in ‘smoking addiction’. There is also evidence linking it to the development of diabetes, obesity, cardiovascular disease, respiratory disease, digestive disease, neurological disease, and even a link to the development of cancer. From this point alone, those manufacturers who advertise ‘no harm’ should be fined for false advertising. And that’s not even mentioning the ones that claim to clear the lungs or be an aphrodisiac here! The nicotine content of e-cigarette oils or cartridges on the market fluctuates greatly, and many of them have a higher nicotine content than real cigarettes. It is important to know that the nicotine content of a real cigarette (about 1mg) can kill a mouse, and for a 30kg child, 24mg of nicotine will be fatal poisoning risk.

Although cigarettes are smoked in sips, they are still harmful when smoked consistently. Moreover, for old smokers, if they smoke vaping with excessive content, not to mention reducing their dependence on nicotine, but may increase their dependence……. And with all kinds of flavored oils, who knows what kind of chemical additives and flavors have been added inside! The additives and flavors inside may have health risks, some even found formaldehyde, acrolein and other harmful gases.

What are the health hazards of vaping?

Suppression of immune genes By comparing the immune cells in the noses of e-cigarette users, traditional cigarette smokers and non-smokers, it was found that  vaping suppresses 358 immune genes in a person’s nose, while 53 immune genes are suppressed in ordinary smokers. Suppression of immune genes leads to a sharp decline in human resistance to external bacteria, resulting in a variety of diseases. This also means that at the point of suppressing the number of immune genes in the human body – vaping are 7 times more harmful than cigarettes!

Triggering cardiovascular disease Since then, the researchers have launched a study on the e-cigarette smoke liquid, the results of the study again shocked the world: e-cigarette smoke aerosol also causes an increase in the aggregation of platelets, which may lead to the emergence of blood vessels in the micro-thrombosis. This means that vaping are no less harmful than traditional cigarettes in terms of increasing cardiovascular risk and causing heart attacks!

Prone to cancer Subsequently, researchers also found that the aerosol produced by the battery-heated cigarette liquid also contains cardiovascularly harmful aldehydes, including formaldehyde, acetaldehyde and acrolein. The harm of these organic gases needs no further explanation, right? Every household knows to leave their house open for a while after renovation to allow formaldehyde to evaporate. Today, however, people are inhaling formaldehyde into their bodies through vaping!

Causing fatal lung disease In the e-cigarette step by step was confirmed, “health halo” does not exist, another experiment results directly into the “villain” camp, it was found to bring an additional fatal risk! –Those who have vaped must have lingered on the different flavors of vaping, strawberry, blueberry, peach, mint …… Where does this sweet taste come from? This is due to the addition of a substance, diacetyl, to the cigarette oil. This substance causes a serious lung disease – occlusive bronchitis. This is a rare, fatal and irreversible form of obstructive lung disease that causes the lungs to gradually fail. If you suffer from this disease, you may have to spend a long time pumping blood, not to mention smoking.

Conclusion

The conclusion is that the lack of cancer risk from vaping is reduced compared to traditional cigarettes, but they are not a healthy alternative. vaping are not completely harmless and there is still a risk of cancer. The healthiest option is to stay away from all tobacco and nicotine products. If there is only one cancer prevention tip that a person learns in their lifetime, it is to stay away from tobacco.
