Almost two-thirds of Australian women do not understand the difference between cervical and ovarian cancers, believing a Pap smear tests for both diseases.
Research released by Ovarian Cancer Australia to mark today's Teal Ribbon Day also shows half of women wrongly think the human papillomavirus vaccine that protects against cervical cancer also stops ovarian cancer.
The group said the research showed the need for education in women of all ages.
Each year, about 1300 Australian women are diagnosed with ovarian cancer and more than 800 die of the disease.
Teal Ribbon Day is supported by celebrity ambassadors and women living with ovarian cancer who encourage women to recognise the main symptoms of ovarian cancer.
These include abdominal or pelvic pain, increased abdominal size or persistent bloating, the need to urinate often or urgently, and feeling full after eating a small amount.
Proceeds raised from the sale of teal ribbons go towards research and support programs for women with ovarian cancer and their families.
