Ovarian cysts are fluid filled tumours that arises from one or both ovaries.

    - Menstrual lining and menstrual blood embedded in the ovary and enlarges in
      size
    - "Chocolate cysts"
    - Associated with infertility
    - Lower abdominal pain or painful menses

3. Benign Ovarian Cysts (non-cancerous)
    Various types e.g.
    - Serous cystadenoma (30% cancer risk)
    - Mucinous cystadenoma (5-10% cancer risk)
    - Dermoid cyst - oil, hair, cartilage, teeth

4. Ovarian Cancer
    - Less than 5% of all ovarian cysts

Operation

1.	Ovarian Cystectomy Removal of cyst and conserving the ovary for hormonal function especially for young women
2.	Oophorectomy Removal of whole ovary - if most or all of the cyst has occupied the whole ovary
3.	Total Hysterectomy & Bilateral Oophorectomy Removal of both ovaries and the uterus
