A new study based on 80,000 postmenopausal women found that first-hand and second hand smoking raises risk of breast cancer cancer. investigation was done by Dr. Juhua Luo from West Virginia University and Dr. Karen Margolis from Health Partners Research Foundation, and published in the British Medical Journal. Luo and Margolis analysed data from 80,000 women, there were between 50 and 79 years. data came from women's health initiative Observational Study 1993-98, and included patients from 40 clinics around the United States. ten years after the data is taken, 3,250 women developed cases of invasive breast cancer.
Study results show that smokers have a 16% greater risk of developing postmenopausal breast cancer compared with women who had never smoked. former smokers has an average of 9% increased risk of breast cancer, but the risk was worst for women who smoked since their teen years or 50 years or longer. even 20 years after a woman stops smoking, her risk is still higher than lifetime average risk of breast cancer.
Some of the women in this study had never smoked, but had been exposed to second-hand smoke. those who had suffered extensively for passive smoking in ten years in childhood, 20 years during adulthood at home, or 10 years as adults in the workplace had 32% excess risk for breast cancer. so if you had a parent, smoked when you were a kid, or a spouse or partner who smoked at home or coworkers, who smoked around you on the job, they have not done any services.
Dr. Karen Margolis believes that we all would be healthier if none of us smoked at any stage of life. "our findings highlight the need for interventions to prevent the initiation of smoking, in particular at an early age, and to promote non-smoking cessation of all ages". bottom line is: non-smoking, avoid those who smoke, and get help to stop smoking. lower than the average risk of breast cancer is just one advantage you getWhen you stop smoking, there are many more good things about giving up smoke.
