“The pill” slightly raises breast cancer risk in younger women

“The pill” slightly raises breast cancer risk in younger women. That is the conclusion of a recent analysis of 34 studies of breast cancer and oral contraceptive use. All the women in the studies were pre-menopausal (or younger than 50) and used oral contraceptives, often called “the Pill.” In particular, the report found that women who used oral contraceptives prior to their first full-term pregnancy had a 44% higher risk of developing breast cancer than women who had never taken the Pill. At highest risk were those who had used oral contraceptives for 4 or more years before having their first child. Other studies have shown that increased breast cancer risk disappears 10 years after a woman stops taking the Pill. And overall, the risk of breast cancer among women who take the Pill is small. Still, the researchers say, doctors should discuss with younger women the risks and benefits of oral contraceptive use. Aside from contraception, benefits include a measure of protection against ovarian and endometrial cancers.
