These studies highlight the broad benefits of smoking cessation not only for lung cancer but also for other cancers, with risk reductions ranging from 14% for stomach cancer to 42 % for lung cancer.
Nicotine addiction is a problem for millions of people. It affects people’s health. This is stated in a large-scale study involving more than 2.9 million people. Scientists have discovered that quitting smoking can significantly reduce the risk of developing various types of cancer. The Daily Mail writes about it.
“The analysis showed that people who stopped smoking had a 17% lower risk of developing cancer compared to those who continued to smoke. Smoking has long been recognized as a major risk factor for several types of cancer, including the lungs, stomach, colon, liver, pancreas and kidneys. The increased risk is due to harmful toxins in cigarette smoke, which can impair the immune system’s ability to effectively fight cancer cells,” said experts.
The study involved Koreans aged 30 years and above. They underwent two consecutive medical examinations starting in 2002 with follow-up until 2019. During an average follow-up period of 13.4 years, 197,000 cases of cancer were identified among nearly three million participants.
An initial increase in cancer risk was observed within seven years of smoking cessation. This is explained by the “sick quitter” effect. However, this term refers to people who quit smoking not as a preventive measure, but usually because they already have health problems due to smoking. However, the long-term benefits of quitting smoking are clear.
“Among people who quit smoking completely, the risk of developing cancer decreased by 17% compared to those who did not quit, and the reduction in risk became more significant over time. 15 years after quitting smoking, the risk of developing cancer was cut in half. Especially notable was the rapid reduction in the risk of developing lung cancer, which began to decline three years earlier than the risk of other types of cancer. Those who stopped who smoked before age 50 had a 57% reduction in the risk of developing lung cancer compared to those who quit smoking later in life,” the researchers added.
Remember that earlier scientists said that smoking increases the risk of dementia more than cancer.
