Q

Why is ovarian cancer frequently diagnosed at an advanced stage?

often diagnosed at an advanced stage due to non-specific symptoms, which can result in the disease being widely metastatic within the abdomen by the time it is detected

A

Return to normal recall.

47
Q

Cervical screening: What should be done if the 2nd repeat smear test at 24 months is still hrHPV positive?
