MONTREAL, Nov. 1 (UPI) -- Women with lung cancer live longer than men, even when the disease is untreated, a study suggests.

The study -- presented at the annual Chest 2005 medical conference -- showed women not only have better lung-cancer survival odds than men, but also that women with untreated lung cancer have a 21 percent decreased risk of death, compared to their male counterparts.

Specifically, researchers found a 54 percent five-year survival rate for women, compared to a 40 percent rate for men, and women receiving treatment for the disease had a 30 percent decreased risk of death compared to male lung-cancer patients.

Researchers suspect the disparity may be because the deadly disease acts differently depending on gender and is more aggressive in men.

The epidemiological study -- conducted at Mount Sinai School of Medicine in New York City -- focused on 18,967 cases of stage 1 and stage 2 non-small-cell lung cancer diagnosed between 1991 and 1999. The study drew from a Medicare database that tracks the disease.
