EUGENE, Ore. – A new study shows birth control pills, patches or other hormonal contraceptives could give women an increased risk of breast cancer.
Researchers in Denmark looked at 1.8 million women and found using any type of hormonal contraceptive was linked to a 20 percent high risk of breast cancer.
Those who used them longer were at a greater risk.
Researchers said the overall risk of breast cancer is still small for many women.
Past research suggests birth control bills protect against other types of cancer.
