Can Long-Term E-Cigarette Use Cause Cancer?

Does long-term use of e-cigarettes cause cancer? Everyone knows the carcinogenicity of traditional cigarettes, which contain many harmful substances. E-cigarettes were invented to reduce this harm, but do they also pose a cancer risk? This is a concern for many, so today we will discuss this issue in detail.
 
Does long-term use of e-cigarettes cause cancer? General Answer

Yes, it can cause cancer. Tobacco contains a significant amount of nicotine, and e-cigarettes also contain harmful substances.

Some e-cigarette products have high nicotine content, and the carcinogenic substances they contain can be as harmful to human health as traditional cigarettes. Additionally, because e-cigarette devices heat too quickly, they produce a highly toxic molecule called acrolein, which is very harmful to the body.

Nicotine can cause acute symptoms such as blood vessel constriction, increased heart rate, elevated blood pressure, and rapid breathing. Research has shown that nicotine can inhibit chemotherapy drugs like paclitaxel from killing lung cancer cells, thereby protecting cancer cells. Another serious harm of nicotine is its addictive nature, which leads to dependence and is one of the reasons for the difficulty in quitting smoking.

Does long-term use of e-cigarettes cause cancer? What doctors say

Long-term use of e-cigarettes can cause cancer, just like traditional cigarettes. Currently, smokers are about fifteen times more likely to develop lung cancer than non-smokers. Cigarettes contain a large amount of coal tar, nicotine, benzo[a]pyrene, and other carcinogenic substances. Long-term smoking, especially smoking 20 cigarettes a day for over 20 years, puts individuals at high risk for lung cancer. Lung cancer currently has the highest incidence rate. Early symptoms may include paroxysmal cough, while later stages may present with phlegm or blood in the sputum, often accompanied by weight loss. Chest CT scans can reveal lung masses, and biopsy or bronchoscopy can confirm the diagnosis.
 
Does long-term use of e-cigarettes cause cancer? Research findings

Numerous studies have found that known carcinogenic aldehydes, such as formaldehyde, are present in the gases released by e-cigarettes. However, researchers disagree on whether these toxic substances in e-cigarettes are sufficient to harm users.

For example, a study published this year confirmed that the number of aldehydes formed during the chemical decomposition of e-liquid in e-cigarettes has reached dangerous levels and can be released with the vapor.

According to recent reports from professorhealth.org, a research team from the Desert Research Institute (DRI) and the University of Nevada recently conducted a study and found that during e-cigarette use, a large number of carcinogenic chemicals like formaldehyde are absorbed by the respiratory tract and remain in the lungs. This study was published in the journal "Toxics."

Does long-term use of e-cigarettes cause cancer? NYU School of Medicine Research

Recently, a study from NYU School of Medicine indicated that using e-cigarettes may increase the risk of cancer or heart disease. The research team found that if laboratory mice were exposed to a "low dose" e-cigarette environment for 12 weeks (equivalent to 10 years for humans), many of the mice had DNA damage, and their bladders, hearts, and lungs showed pathological changes, with issues in DNA repair and lung protein functions. Overall, nicotine will always turn into carcinogens in your body, regardless of how it occurs.

Does long-term use of e-cigarettes cause cancer? Summary

In summary, long-term use of e-cigarettes does carry a certain cancer risk. Although nicotine itself may not be carcinogenic, it may indirectly lead to cancer. Therefore, if you do not have a nicotine addiction, it is not recommended to use e-cigarettes. Additionally, current e-cigarettes are not regulated, leading to quality discrepancies, so caution is advised.
