Quitting smoking reduces cancer risk after 10 years

Quitting smoking significantly reduces the risk of developing cancer in the first ten years. One detects it Korean study published in the journal JAMA.

It’s never too late to quit smoking

According to the research, conducted on 2.9 million Korean adults, permanent cessation of smoking is associated with a significant reduction in cancer risk ten years after stopping. Quitting at any age helped reduce cancer risk, and especially for lung cancer, quitting before middle age showed a substantial reduction in cancer risk. Giving up the habit of smoking is, therefore, a good investment both from an economic and health point of view. Quitting helps reduce the risk of developing many pathological conditions.

Less passive smoking, healthier children

Furthermore, the decision to give up the habit by a smoker is an altruistic choice, as it limits exposure to secondhand smoke for the people who frequent it, for example reducing the risk of many diseases in children, such as respiratory diseases, such as asthma, and ear infections, such as ear infections.

What happens as soon as we stop smoking

According to the American Cancer Society, if you stop before reaching the age of 35, the negative consequences of smoking are reduced by 90%. Within 20 minutes from the last cigarette the heart rate and blood pressure decrease. Within 12 hours Nicotine and carbon monoxide levels in the blood decrease and oxygen returns to normal levels: muscles work better and sleep improves. Within a period between 2 weeks and 3 months about blood circulation and lung functions improve.
From the first to the ninth month coughing and shortness of breath decrease and you feel more physically active. Within a year the risk of heart attack is halved and after the first 5-15 years the risk of stroke becomes the same as that of a non-smoker.

Reducing the risk of cancer

In the 10 years following cessation of smoking, the risk of lung cancer is reduced by up to half and the risk of developing cancer of the mouth, throat, esophagus, bladder, cervix and pancreas also decreases. Within 15 years the risk of developing chronic conditions becomes the same as that of a non-smoker.

The increase in life expectancy

Quitting smoking at 30 allows you to gain at least 10 years of expected life; at 40 it’s 9 years; at 50 years 6 years and at 60 years 3 years. Furthermore, stopping smoking also brings benefits to those who have already developed smoking-related diseases, reducing the probability of having a heart attack by 50% in those who stop smoking after a heart attack, it reduces the risk of impotence, miscarriage or to give birth to premature or low birth weight babies.
