A study published in the Journal of Clinical Oncology found that smoking cessation significantly reduces the risk of developing various types of cancer, including lung, liver, stomach, and colon cancer. The study found that the fastest reduction in risk was for lung cancer, which decreased by 50% three years earlier than other types of cancer.
The study also found that quitting smoking before the age of 50 offers better protection against lung cancer, resulting in a 57% drop in the risk of malignant tumors in the respiratory system. Additionally, stopping smoking after the age of 50 reduces the risk of lung cancer by 39%, compared to those who continued to smoke.
In Israel last year, about 31,000 women and men were diagnosed with cancer, with approximately 11,000 deaths from the disease. The rate of cancer cases in Israel is higher than the world average, with a smoking rate of about 20%, 26% among men and 15% among women. Smoking is responsible for approximately 8,000 deaths per year in Israel and causes at least 15 types of cancer.
Overall, this research highlights the importance of smoking cessation as a way to prevent various types of cancer and improve overall health outcomes.
