Wellbeing, the health research charity for women and babies, is launching a national awareness campaign to increase women's knowledge of ovarian cancer.
Ovarian cancer kills just under 5,000 women in the UK annually but does not have the same visibility among the public as breast cancer, said a charity spokeswoman.
Any woman whose mother, sister or aunt has had either breast or ovarian cancer is at greater risk of developing ovarian cancer themselves. The campaign will highlight this but also clarify the symptoms in order to encourage more self-diagnosis while avoiding mass hysteria, said the spokeswoman.
The "Say knickers to ovarian cancer
campaign will mail information leaflets to health authorities and GP practices nationally as well as targeting radio and print media. There are no plans for paid advertising.
