According to more than 40 years of research, the contraceptive pill can protect women against certain types of cancer.
The study, which was carried out at the University of Aberdeen, reports that women are less likely to suffer from bowl cancer, endometrial cancer and ovarian cancer after using the pill, and it can protect you for up to 30 years after.
The research, which studied 46,000 women for 44 years, also debunked the myth that taking the pill can lead to breast cancer in later life – it does not.
The Oral Contraception Study first began in 1968, by the Royal College of General Practitioners to investigate the side effects of taking birth control.
Dr Lisa Iversen, the lead researcher said: "What we found from looking at up to 44 years' worth of data, was that having ever used the pill, women are less likely to get colorectal, endometrial and ovarian cancer.
"So, the protective benefits from using the pill during their reproductive years are lasting for at least 30 years after women have stopped using the pill.
"We did not find any evidence of new cancer risks appearing later in life as women get older.
"These results from the longest-running study in the world into oral contraceptive use are reassuring.
"Specifically, pill users don't have an overall increased risk of cancer over their lifetime and that the protective effects of some specific cancers last for at least 30 years," she added.
