From John Gray
You discuss the relative merits of the pill and the coil for birth control (28 October, p 7). I understand that the pill may also mitigate against the awful, often fatal, disease of ovarian cancer.
Few people seem to hear about this until they have a dear relative with the disease or they get inside a cancer ward. A large trial of ovarian cancer screening has just begun, though the results are not due out for another six years – see www.medicine.manchester.ac.uk/abouttheschool/news/cancermilestone
