Breast Examination
• Obtain History• Perform Clinical Breast Exam• Discuss/teach monthly self breast exam• Refer for Mammography at age 35/40
• Most Common Breast Problems—breast pain (mastalgia), nipple discharge, palpable mass
• Address symptoms• Rule out malignancy
![Page 3: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/3.jpg)
Breast Pain
• More common in premenopausal women• Rarely a presenting symptom of breast
cancer• May be cyclic or non-cyclic (hormonal/fluid
retention?)• Fibrocystic disease-studies do not show a
causal relationship, may or may not be present in histologic findings
![Page 4: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/4.jpg)
Breast Pain
• Obtain info on type of pain, location, & relationship to menstrual cycle
• Cyclic pain is usually bilateral & poorly localized
• Usually resolves spontaneously
• Non cyclic pain is usually a sharp, burning localized pain
• May be secondary to an underlying fibroadenoma or cyst
• Both types may be exacerbated by stress, medications, nicotine, caffeine
![Page 5: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/5.jpg)
Nipple discharge
• Often a benign process• First step is to determine whether the
discharge is pathologic or physiologic• Pathologic--spontaneous, bloody, often
associated with a mass-usually unilateral & confined to one duct. Most common cause is intraductal papilloma.
• Physiologic—discharge only with compression, multiple duct involvement
![Page 6: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/6.jpg)
Nipple Discharge Work-up
• A careful history can usually identify a physiologic discharge. If coexisting abnormalities &/or more than 35 years old-complete exam & mammography. Usually goes away when nipple is left alone.
• All spontaneous or unilateral nipple discharge should be referred for surgical exam
![Page 7: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/7.jpg)
Palpable Breast Mass
• In premenopausal women normal glandular tissue is nodular (most pronounced in the upper outer quadrant & the inframammary ridge)
• Nodularity is a physiologic process & not an indication of breast pathology
• Differential diagnosis of a dominant breast mass: macrocyst, fibroadenoma, fibrocystic changes, fat necrosis, & cancer
![Page 8: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/8.jpg)

Breast Disease Summary• Most common
problems are breast pain, nipple discharge, & a palpable mass
• Goal of the evaluation is to address the symptoms & rule out cancer
![Page 11: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/11.jpg)
Preinvasive Disease of the Cervix& Cervical Cancer
• Cervical Cancer is the second most common type of cancer in women worldwide.
• A causal link exists between HPV & cervical neoplasm.
• The presence of high-risk HPV types increases the risk of malignant transformation.

Other Risk Factors That Affect Susceptibility to HPV subtypes
• Smoking• Nutrition• Coexisting STI• Genetics
More severe infection may occur in women with immunosuppression.
CDC advises semiannual screening with pap smear the first year after diagnosis; then may revert to annual screening if no cytological abnormalities detected.

Pap smears that suggest invasive disease require further
evaluation by: colposcopy, biopsy, endocervical curettage, cryotherapy laser vaporization,
loop excision, cone biopsy, hysterectomy
![Page 25: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/25.jpg)
Uterine CancerRisk Factors• age (75% menopausal-late 60s)• obesity (especially upper body type)• PCOD• Unopposed exogenous estrogen• Diabetes• Personal or family history of ovarian or breast
cancer• Nulliparity• Late Menopause (after age 52)
![Page 26: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/26.jpg)
Uterine Cancer• Directly related to the amount of estrogen
stimulation & endometrial hyperplasia• Postmenopausal bleeding is endometrial cancer
until proven otherwise• Early in disease state, normal findings on
examination• Metrorrhagia (any nonmenstrual or
intermenstrual bleeding)• Lower abdominal pain/pressure (10% of cases)• Rarely back pain or edema in lower extremities
secondary to metastasis
![Page 27: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/27.jpg)
Diagnostic Evaluation for Endometrial Cancer
• Endometrial Biopsy• D&C (allows for more extensive sampling)• Transvaginal Uterine Sonography (endometrial
thickness <6mm, usually not associated with cancer)
• Hysteroscopy with directed biopsy (useful in staging)
• Pap Smear may be detected as “endometrial cells”
• Type 1—most common type is hormone sensitive, low stage, with excellent prognosis
![Page 28: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/28.jpg)
Staging for Endometrial Cancer (see handout)
• FIGO staging for endometrial cancer• Stage IA G123: tumor limited to endometrium. • Stage IB G123: invasion to less than one half the myometrium. • Stage IC G123: invasion to more than one half the myometrium. • Stage IIA G123: endocervical glandular involvement only. • Stage IIB G123: cervical stromal invasion. • Stage IIIA G123:tumor invades serosa and/or adnexa, and/or positive
peritoneal cytology. • Stage IIIB G123:vaginal metastases. • Stage IIIC G123:metastases of pelvic and/or para-aortic lymph nodes. • Stage IVA G123: tumor invasion of bladder and/or bowel mucosa. • Stage IVB: distant metastases including intra-abdominal and/or inguinal
lymph nodes. • References• FIGO staging for corpus cancer. Br J Obstet Gynaecol 99(5): 440, 1992. • Corpus uteri. In: American Joint Committee on Cancer.: AJCC Cancer

Ovarian Cancer
• Risk factors-unopposed estrogen stimulation (anovulatory cycles, infertility, infertility drugs, nulliparity, low parity, exposure to toxins/carcinogens (dietary fat, perineal talc use, asbestos exposure)
• Heredity (breast, ovarian, Lynch II Syndrome-familial predisposition to breast, endometrial, colon, prostate, ovarian cancers)
![Page 30: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/30.jpg)
Ovarian Cancer (cont)• Etiology-unknown
• Classification based on type-
a) epithelial cell tumors (>90%; increases with age)
b) germ cell tumors (most common in children/young adults)
c) sex cord-stromal tumors (rare-usually occur in postmenopausal women)
![Page 31: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/31.jpg)
Clinical Presentation of Ovarian Cancer
• Abdominal bloating• Dyspepsia• Frequent urination• Pelvic pressure or
pain• Constipation
• Pelvic mass• Abdominal
distention• Pleural effusion• Ascites• Adenopathy• Cachexia
Symptoms are notoriously vague & nonspecific
![Page 32: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/32.jpg)
Diagnostic Evaluation for Suspected Ovarian Carcinoma
• Pelvic exam• Pelvic transvaginal utrasonography• Color flow doppler of ovarian vessels• Serum tumor markers (i.e., CA125)• Serum beta HCG (germ cell tumors)• Genetic testing (BRCA1)
• Preoperative staging tests—CXR, CBC, serum chemistries, IVP, cystoscopy, proctoscopy, barium enema
• Surgery (definitive diagnosis & staging)
![Page 33: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/33.jpg)
Staging for Ovarian Cancer• Staging System • Stage I: Ovarian cancer that is confined to one or both ovaries. Stage II:
Ovarian cancer that has spread to pelvic organs (e.g., uterus, fallopian tubes), but has not spread to abdominal organs. Stage III: Ovarian cancer that has spread to abdominal organs (e.g., abdominal lymph nodes, liver, bowel). Stage IV: Ovarian cancer that has spread outside to distant sites (e.g., lung, brain, lymph nodes in the neck). Recurrent: Ovarian cancer that has recurred (come back) even though the patient has completed treatment. Once ovarian cancer is assigned a stage, the classification does not change, even if the cancer recurs or metastasizes to other sites within the body.
• Ovarian cancer staging usually is described in terms of the FIGO system (staging scheme developed by the International Federation of Gynecology and Obstetrics) and the TNM system (classification system developed by the American Joint Committee on Cancer [AJCC]). According to the TNM system:
• T = Tumor SizeN = Node InvolvementM = Metastasis Status
• Ovarian cancer treatment ultimately depends upon such staging. In general, the lower the stage, the more favorable is the prognosis
![Page 34: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/34.jpg)
Treatment Options & Prognosis for Women with Ovarian Cancer
• Early Stage: Surgery--Five year survival rate >90%
• Advanced Stage: Chemotherapy, autologous bone marrow transplantation, hormonal therapy Five year survival rate 30-40%
![Page 35: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/35.jpg)
Dysfunctional Uterine Bleeding
• Definition: the bleeding manifestations of anovulatory cycles
• Causes: a thickened endometrium causes by perimenopause, puberty, PCOS, obesity, unopposed estrogen replacement therapy
• Other patterns of DUB: estrogen low relative to progesterone; results in a thinned endometrium (low estrogen pills < 30 mcg, POP, Depo-Provera, Norplant, Mirena IUS)
![Page 36: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/36.jpg)

Clinical Presentation of DUB
• Acute: orthostatic BP changes, > heart rate, pallor, large amount of blood in vaginal vault, uterus may be enlarged due to retained clots
• Chronic: stable heart rate & BP, body habitus (obesity, stigmata of PCOS), pale or normal skin color, small amount or no blood in vaginal vault, uterus WNL

• Luteinizing Hormone• Follicle-stimulating hormone• Thyroid Function Tests• Prolactin• Testosterone• Hysteroscopy• Ultrasound
![Page 41: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/41.jpg)
Differential Diagnoses for Abnormal Uterine Bleeding
Hormonal: a) anovulation (anorexia, puberty, perimenopause, obesity, hypothyroidism, extreme stress, prolactinoma, PCOS), b) BTB on OCPs, POPs, DepoProvera, HRT, etc
Anatomic & Physiologic: cancer (cervical, endometrial, ovarian), polyps (cervical, endometrial), uterine fibroids, pregnancy (SAB, ectopic, molar), ovulation, postpartum (atony, retained placenta, subinvolution)
![Page 42: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/42.jpg)
Differential Diagnosis (cont)
Infectious: cervicitis (CT), endometritis (postpartum), PID (GC)
Hematologic: bleeding diathesis ( idiopathic thrombocytopenia purpura, hemophilia, various blood dyscrasias)
![Page 43: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/43.jpg)
Pharmacologic Treatment Options
• DUB may be severe enough to cause anemia. Several measures may help: non-steroidal anti-inflammatory drugs (such as ibuprofen), progestins (provera and others), birth control pills, danazol (a weak androgenic hormone which causes suppression of ovarian estrogen/progesterone production) and GnRH agonists (gonadotropin releasing hormone agonists) such as Lupron, which lead to suppression of ovarian estrogen/progesterone production.
![Page 44: Women’s Health--GYN Megan Louque, RN, CNS, ANP, FNP](https://reader033.vdocument.in/reader033/viewer/2022051401/56649ddf5503460f94ad843a/html5/thumbnails/44.jpg)
Non-Pharmacologic Treatment Options for DUB
• Endometrial Ablation
• Hysterectomy (last resort)
