Tumor Markers

Vaginal diagnostic ring device, comprising a diagnostic sensor for performing an intravaginal diagnosis or measurement therefor, wherein the device further comprises a first rigid member having a first and second end;

• a second rigid member having a third and fourth end;
• a first flexible member coupled between the first and third ends;
• a flexible part coupled between the second and fourth ends;
• wherein the first flexible member and/or flexible part are configured for allowing the device to be squeezed by bringing the second and fourth ends together thereby transforming a shape of the device from an extended shape to a collapsed shape for allowing the device to be inserted into a vagina of a user at or near the fornix posterior vaginae, said extended shape corresponding to a substantially oval or annular ring shape;
• wherein at least one of the first flexible member and the flexible part is at least partially elastic such that the device is prebiased to assume the extended shape when no external force is being applied thereto, characterized in that the diagnostic device is configured for detecting a tumor marker.
