Study finds similar association of progestogen-only and combined hormonal contraceptives with breast cancer risk

There is a relative increase of 20% to 30% in breast cancer risk associated with both combined and progesterone-only contraceptives, whatever the mode of delivery, though with five years of use, the 15-year absolute excess incidence is at most 265 cases per 100,000 users, according to a new study.
