Researchers have found that smoking may increase the risk of dying early in premenopausal women with breast cancer.

In a prospective study of 848 women with who were followed for a median of 6.7 years, premenopausal women who smoked for more than 21.5 years had a 3.1-times higher risk of dying from any cause as well as a 3.4-times higher risk of dying from breast cancer. These links were not apparent among post-menopausal women.

There was also some suggestion that the increased risks seen in were especially relevant to women whose cancers expressed both the estrogen receptor and the progesterone receptor.

"Overall, this work is monumental in advising patients about how their smoking might affect their outcome," said Dr. Yuko Minami, co-author of the Cancer Science study. "Hopefully this paper will serve to reduce the number of who continue to smoke."
