Birth Control Pills Still Linked to Breast Cancer, Study Finds
Women who rely on birth control pills or contraceptive devices that release hormones face a small but significant increase in the risk for breast cancer, according to a large study published on Wednesday.
The study [DOI: 10.1056/NEJMoa1700732] [DX], which followed 1.8 million Danish women for more than a decade, upends widely held assumptions about modern contraceptives for younger generations of women. Many women have believed that newer hormonal contraceptives are much safer than those taken by their mothers or grandmothers, which had higher doses of estrogen.
The new paper estimated that for every 100,000 women, hormone contraceptive use causes an additional 13 breast cancer cases a year. That is, for every 100,000 women using hormonal birth control, there are 68 cases of breast cancer annually, compared with 55 cases a year among nonusers.
While a link had been established between birth control pills and breast cancer years ago, this study is the first to examine the risks associated with current formulations of birth control pills and devices in a large population.
The study found few differences in risk between the formulations; women cannot protect themselves by turning to implants or intrauterine devices that release a hormone directly into the uterus.
The research also suggests that the hormone progestin — widely used in today's birth control methods — may be raising breast cancer risk.

Just let the contraceptive aside and you'll have both kinds**

E.g. boobs - limited to only two per person. Lately, the menist movement registered a leap ahead in physical (boobs) equality.

Yeap. But, naturally, you still have only two of them.

You have to go to a furry convention for more than that, I guess.

Surprise: polymastia [wikipedia.org] is said to be most prevalent in male humans.
