A groundbreaking study has discovered that halting smoking, irrespective of the individual's age, considerably diminishes the risk of cancer, throwing new light on the importance of health testing and lifestyle modifications. Smoking remains the premiere cause of cancer, causing around 150 cases across the UK daily. Most smokers have attempted to quit The Core Research Findings Health examinations and medical data from almost 3 million Koreans were meticulously analyzed between 2002 and 2019, noting cancer occurrences such as lung, liver, stomach, and colorectal tumors. It was observed that nearly 200,000 participants received a cancer diagnosis during the course of the study period. A significant reduction in cancer risk was reported within the first decade of smoking cessation. People who had quit smoking for at least 15 years showed their chances of developing cancer reduced by half compared to those who continued smoking habits. Furthermore, the risk of lung cancer decreased more rapidly and drastically, especially among those who quit smoking before middle age. Lung Cancer and Smoking Lung cancer is the most prevalent type of cancer and the largest preventable cause of cancer-related deaths. From the research, it was found that smokers who quit before they turned 50 saw a 57% drop over the follow-up period in their lung cancer risk, compared to those who continued to smoke. Even those who quit at 50 or later saw a 40% reduction in lung cancer risk during the same period. Quitting smoking, no matter what your age, has significant health benefits, says Dr. Jin-Kyoung Oh, who led the study at the National Cancer Center near Seoul. Always remember, its never too late to quit smoking. We encourage you to start your journey towards a smoke-free life. Tobacco Smoke and Other Cancers The study also observed Tobacco smoke can also lead to a variety of other cancers, including those of the bladder, stomach, bowels, and organs such as the kidneys and liver. The risk of such cancers also saw smaller falls between 14-27% upon quitting smoking. Health Examination and Testing As per the study correlation between smoking cessation and reduction in cancer risk, the importance of regular health examination and testing becomes paramount. The development of cancer is generally a multistage process, with gradually accumulating DNA mutations that eventually lead to some cells replicating uncontrollably, explains Robert West, Professor Emeritus of health psychology and an expert on addiction. The sooner a smoker ceases the habit, the lower the likelihood they will develop cancer. The study underscores the importance of testing for early detection of cancer, specifically lung cancer, among smokers and the general populace. Current tests for lung cancer primarily include imaging tests (like chest X-rays or CT scans) and tissue sample tests (biopsies). Cancer Prevention and Quitting Smoking For smokers, its crucial to quit as young as possible. The younger smokers can stop, the more of their lives they get back, Prof West adds. The path to quit smoking is simple: make annual attempts to quit and avail evidence-based specialist stop-smoking support at every quit attempt instead of trying to go 'cold turkey'. Advocates for a Smoke-Free World This extensive study has highlighted the tangible health benefits linked to quitting smoking, no matter what age the habit is stopped. The reduced risk of various cancers stands as a stark reminder of the importance of cessation of smoking and comprehensive support and initiatives to encourage smokers to quit.
