  46. 1.  Describe conservative and surgical management of leiomyomas.
    1.  No treatment is necessary for small and asymptomatic leiomyomas.

    If the patient is severely anemic due to bleeding, progesterone given IM every 28 days and 300 mg of iron will help.

    Estrogen only therapy is usually limited to women who no longer have a uterus.

    • Exogenous estrogen is contraindicated in patients with estrogen dependent cancers, such as breast, and endometrial and ovarian cancers, or on diagnosed vaginal bleeding.
    • Patients with liver disease, active thrombosis or history of stroke should not take estrogen.  Pregnancy and migraine headache are other contradictions to taking estrogen.

    1.  Ovarian cancer has 3 main classifications; surface epithelial- stromal tumors( by far the most common life-threatening represent 80 to 90% over wearing tumors), sex cord - stromal tumors, and germ cell tumors.

    Ovarian cancer is quantitatively the rarest but the most deadly form of gynecological cancers.

    Ovarian cancers have been associated with the number populations in a woman's lifetime; therefore nulli-parity increases the number of ovulations and thereby the risk of a cell mutation occurring.
  55. 1.  Describe the symptoms of ovarian cancer. 

    2.  Describe objective findings of ovarian cancer.
    1.  Symptoms include back pain bloating and constipation.  As a tumor enlarges public pressure, discomfort urinary frequency abdominal swelling bloating and nausea.

    2.  During a pelvic exam, a public Mass, decreased mobility of the cervix and uterus, pain untold patient of the ovaries, and a digital rectal exam may confirm a pelvic mass.  Malignant ovarian tumors are usually large with irregular contour and decreased mobility, unlike benign tumors and cysts.
  56. 1.  Describe ovarian cancer staging.
    1.  Ovarian cancer staging a staged 1 through 4, one being confined to the ovaries and 4 representing distant metastasis.
  57. 1.  Describe management of ovarian cancer.
