Study hypothesis 1. To establish the impact of preclinical detection of ovarian cancer by screening on ovarian cancer mortality
2. To determine the physical morbidity of ovarian cancer screening
3. To determine the resource implications of screening and the interventions which result from screening
4. To record the psychological consequences of screening in the subgroups of true negative, true positive, false negative and false positive screening results
5. To assess the feasibility of population screening for ovarian cancer as reflected by uptake of invitations and compliance rates with annual screening
6. To compare the performance of two screening strategies for ovarian cancer
7. To establish a serum bank for future assessment of novel tumour markers
