Recent use of some oral contraceptives is associated with an increased risk of breast cancer, researchers reported.

In a nested case-control study, women who had used birth control pills within the previous year had a 50% increase in the risk of disease, compared with those who had never or formerly used the drugs.

The risk varied with formulation of the contraceptives; some types -- notably those with low-dose estrogen -- were not associated with cancer.

"Our results suggest that use of contemporary oral contraceptives in the past year is associated with an increased breast cancer risk relative to never or former oral contraceptive use," Beaber said in a statement, adding the risk "may vary by oral contraceptive formulation."
