Ovarian cancer treatment is less likely for those women who have been taking the contraceptive pill long-term.
New research co-funded by Cancer Research UK has found that women who used the combined oral contraceptive pill for ten years saw their chance of developing ovarian cancer fall by 45 per cent compared to those patients who had been prescribed the medication for less than 12 months.
Other factors that were found to be beneficial include pregnancy, with mothers having a 29 per cent reduction in risk when contrasted with those who had never given birth.
"Ovarian cancer is difficult to detect and so prevention is key to saving women suffering from this disease," said Naomi Allen, a Cancer Research UK epidemiologist who helped produce the results.
The charity states the type of treatment used in ovarian cancer cases depends on the individual's tumour, but can include surgery, radiotherapy and chemotherapy.
