Ten percent to 15 percent of lung cancer victims are non-smokers. Among that group, women are two to three times more likely than men to get the disease. Doctors don't know why. Hormones, second-hand smoke, diet and air pollution all are believed to be factors.
Recent research showed that a woman who smokes the same number of cigarettes as a man is twice as likely to develop lung cancer. The study from Sloan-Kettering Cancer Centre in New York suggested that the key to the double tumour risk lies in men having a greater ability to detoxify toxins and the presence of the female hormone oestrogen which is known to help cancers.
In addition, non-smokers who develop lung cancer are two and a half times more likely to be female than male.
Dr Siegfried believes that the higher susceptibility of women to the adverse effects of tobacco could be associated with their higher levels of oestrogen.

Evidence for this comes from two studies which found a greater risk of lung cancer among women who underwent the menopause late in life, and those who had short menstrual cycles. In both cases oestrogen levels were higher than average.
Dr Siegfried believes the hormone may exacerbate the effects of exposure to tobacco smoke - and to other substances known to be linked to lung cancer such as the gas radon.
She said: "The concentration of sex hormones may influence not only the metabolism of the carcinogens in tobacco smoke but also may influence the growth rate of lung tumours."

I hope no defense attorney ever makes the mistake of allowing you to sit on a jury judging his client.
