A study has found that the risk of developing various types of cancer drops significantly after smoking cessation. The reduction in risk included lower incidences of lung cancer, liver cancer, stomach cancer, and colon cancer. Out of all the types of cancer, the risk of lung cancer decreased the fastest following the cessation of smoking, even three years earlier than other types of cancer.
According to research, weaning 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, even stopping smoking after the age of 50 reduces the risk of lung cancer by 39% compared to those who continued to smoke. Last year, about 31,000 women and men were diagnosed with cancer in Israel, with about 11,000 deaths from the disease. The rate of cancer cases in Israel is higher than the world average due to a smoking rate of about 20%, with higher rates among men (26%) and women (15%). Smoking is responsible for approximately 8,000 deaths per year in Israel and causes at least 15 types of cancer.
