Scientists have investigated when it is better to quit smoking and how it affects the development of cancer

The risk of developing cancer is halved at least 15 years after quitting smoking. To prevent the risk of developing the disease, it is better to quit smoking at a young age.
This is the conclusion reached by scientists from the National Cancer Center in South Korea in a study published in the journal Jama Network Open, writes The Guardian.
The scientists analyzed the medical data of nearly 3 million Koreans, each of whom had regular physical examinations between 2002 and 2019. Of these, almost 200,000 patients were diagnosed with cancer.
Scientists have found that smokers who quit before the age of 50 have a 57% lower risk of developing lung cancer compared to those who continued to smoke. At the same time, patients who quit smoking over the age of 50 had a 40% lower risk of developing lung cancer.

Scientists have also discovered the risks of developing damage to certain organs. Thus, among hikers, the risk of developing lung cancer decreased by 42% more than 13.5 years after giving up cigarettes.
And the risks of liver, colon and stomach cancer were reduced by 27%, 20% and 14%, respectively, compared to those who continued to smoke.
“The study confirms two important points. First, it may take many years for the risk of developing cancer to decrease. Second, it is better to stop smoking at a young age to prevent the disease.”– said Robert West, a professor of health psychology at University College London.
For smokers planning to quit, study author Jin-Kyung Oh doesn’t advise using a “start-up” method, but instead giving up the habit gradually. It is better to do it under the supervision of specialists, the scientist added.
We previously reported that by 2050, the number of cancer cases in the world will increase by 77%.
