Cancer is the second leading cause of death worldwide. In every single puff of smoking, more than 80 carcinogens enter the body, directly damaging cellular DNA. Chronic smoking causes an accumulation of genetic mutations in the body's cells, which can ultimately lead to cancer. Recent large-scale studies estimated that 15.1% of new cancers and 21.4% of cancer deaths worldwide are attributed to tobacco use, which is a major preventable risk factor. Quitting smoking can significantly reduce the risks of cancer incidence, progression, mortality, and recurrence, while tobacco control remains the most efficient public health policy for reducing the social cancer burden and protecting public health.
Nicotine replacement therapy (NRT) is a well-evident, safe, and effective aid for quitting smoking. It provides a safe and low dose of nicotine, helping smokers to combat withdrawal symptoms and gradually break free from nicotine and tobacco dependence, and making the quitting process easier. Those wish to quit smoking can contact the Integrated Smoking Cessation Hotline 1833 183 of the Department of Health to acquire more information about NRT and receive appropriate smoking cessation services.
