Q

Give risk factors for ovarian cancer

A

>Age

Genetics

  • HNPCC
  • BRCA 1 and 2

Incessant ovulation

  • Pregnancy and breast feeding is protective as ovaries are dormant during this time
  • Early menarche and late menopause

Oral contraceptive pill reduces risk

Q

What is the screening programme for ovarian cancer?

A

Screening is not effective as there is not a sufficient pre-malignant stage to offer treatment for

However, prophylactic oophorectomy is offered to high risk women (cancer gene mutation carriers, 2 or more relatives)

If dyskaryosis, test vial for HPV

If negative, repeat in 1 year

If dyskaryosis, refer for urgent colposcopy

If 3 inadequate samples in a row, refer for colposcopy

42
Q

What investigation is used in cervical cancer diagnosis

A

Colposcopy and Biopsy

  • Refer if HPV positive and cytology abnormality
