At the recent 32nd meeting of the American Society of Gynecological Oncology, data were presented that suggests that aspirin may lower the incidence of ovarian cancer. In a cohort of 748 women followed for an average of 12 years, and who had taken aspirin for a minimum of 3+ times weekly and for at least six months, there was a lowering of the risk of developing ovarian caner with an odds ratio of 0.6. This equates with a 40% reduction in the risk of developing the disease so says Dr Akhmekhanov who reported the data.
