LONDON — Women who took the birth control pill beginning in the late 1960s lived longer than those never on the pill, a new study says.
British researchers observed more than 46,000 women for nearly four decades from 1968. They compared the number of deaths in women on the pill to those who never took it.
In the study, women on the pill generally took it for almost four years.
Experts concluded the pill cut women's risk of dying from bowel cancer by 38 percent and from any other diseases by about 12 percent.
The research was published Friday in the British medical journal BMJ.
Slightly higher death rates were found among women under 30 on the pill, but that began to be reversed by age 50.
Previous studies have found the pill does not raise the risk of dying. It also may protect against ovarian and endometrial cancer, but slightly increase the chances of breast and cervical cancer.
