     CERVICAL CANCER
     It is the 3rd most common cancer worldwide.

               Most cancers originate in squamous cells, while remainder are adenocarcinomas or mixed
                adenosquamous carcinomas.
               Adenocarcinomas begin in mucus- producing glands and are and often due to HPV
                infection.
               Most cervical cancers, if not detected and treated, spread to regional pelvic lymph nodes.

Conservative treatment:
The following conservative approach may be appropriate:
   1. Resection of the involved ovary
   2. Biopsies of the omentum (a large flat adipose tissue layer nestling on the surface of the
      intra-peritoneal organs) and the involved ovary
   3. Peritoneal washing for cytologic examination of pelvic fluid
   4. Periodic chest x-ray to rule out lung metastasis.

UTERINE CANCER
 It is a slow-growing tumor arising from endometrial mucosa of the uterus, associated with the
  menopausal years.
        P-
 Metastasis occurs through the lymphatic system to the ovaries and pelvis, via the blood to the
  lungs, liver, and bone, or intra-abdominally to the peritoneal cavity.
UN
 The most common gynecological cancer, and the third leading cancer in women.
   Etiology: Unknown
   Risk Factors:
      1. Use of estrogen replacement therapy (ERT)
       - Treating the symptoms of menopause with hormones is known as menopausal
           hormone therapy (or sometimes hormone replacement therapy). Estrogen is the major
           part of this treatment.
                                                                                                   2

 -  Estrogen treatment can help reduce hot flashes, improve vaginal dryness, and help
    prevent the weakening of the bones (osteoporosis) that can occur with menopause.
 - But using estrogen alone (without progesterone) can lead to endometrial cancer in
    women who still have a uterus.
                                                                         E

  - Nulliparous women had a 24% risk of ovarian/uterine cancer compared with women
    with one child, with 50% higher risk of endometroid and a 70% higher risk of clear cell
    ovarian/ uterine cancer

3. Polycystic ovary disease
  - The major reason PCOS increases the risk of endometrial cancer is the prolonged exposure of
     the endometrium to unopposed estrogen caused by anovulation. This prolonged exposure can
                                                                PR
     cause endometrial hyperplasia and may lead to endometrial cancer.
4. Increased age- Most cases occur in women older than age 55.
5. Late menopause
                                                   RE
 - If menopause occurs after age 50, the risk for this cancer might increase as the uterus
 might be exposed to estrogen for more years.
6. Family Hx of uterine cancer
                                           T
   Like many cancers, there is also a genetic link associated with uterine cancer. A family
                               NO
   history that includes a mother, sister or daughter diagnosed with the disease puts women
   at greater risk. In addition, women who have an inherited form of colorectal cancer
   (known as Lynch syndrome) have a 60 percent higher risk of developing uterine cancer.
                   DO
7. Obesity
 - Obesity is a strong risk factor for endometrial/uterine cancer and linked to hormone
   changes. A woman's ovaries produce most of her estrogen before menopause. But fat
        CN
   tissue can change some other hormones (called androgens) into estrogens. This can
   impact estrogen levels, especially after menopause. Having more fat tissue can increase a
   woman's estrogen levels, which increases her endometrial cancer risk.
  P-
 - Gaining weight as you get older age and weight cycling (gaining and losing a lot of weight
   many times in your life) have also been linked to a higher risk of endometrial cancer after
UN
   menopause
8. Hypertension
 - Published observational studies of hypertension and the risk of endometrial cancer and
   our results confirm that hypertension is a strong risk factor for endometrial cancer with a
   61% increase in the relative risk
9. Diabetes mellitus
  - Disorders associated with hyperglycemia (Type I and II diabetes mellitus) have an increased risk
     of Endometrial/ uterine Cancer, indicating that poor control of blood glucose may be an
                                                                                                       2
Diagnostic Evaluation:
     1. Pelvic examination -may reveal an enlarged uterus, and endocervical aspirate may show
       abnormal cells.

Management:
