SYNOPSIS: A large case-control study using the Danish National database found a slight increase in the risk of glioma in ever-users of hormonal contraception, which increased with duration of use. Users of progestin-only methods were at higher risk. However, these findings should not influence clinical practice or perception of contraceptive safety.
