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 breast cancer 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 premenopausal women were especially relevant to women whose cancers expressed both the estrogen receptor and the progesterone receptor.
