Long-time smokers may face an increased risk of death if they develop breast cancer, according to a Japanese study that adds to a growing body of evidence highlighting the lethal effects of cigarettes.
Among more than 800 women with breast cancer, those who had smoked for more than two decades had at least triple the odds of dying of any cause, or from breast cancer in particular, compared with women who never used cigarettes.
Fewer years of smoking were also linked to an increased risk of death from breast cancer, but the extra risk was so small that it might have been due to chance.
