Duct systems in each breast have their own opening at the nipple
Breast tissue remains inactive until pregnancy
Pregnancy and breastfeeding
1. Lobules grow and begin to produce milk which is then released into the ducts
2. Muscle tissue in the nipples allows them to become erect in response to stimulation or breastfeeding
3. Muscle tissue around the lobules helps squeeze milk into the ducts
4. Montgomery's glands on the areola release small amounts of fluid during breastfeeding to lubricate the nipple
Breast changes after menopause
Number of lobules decreases and those that remain shrink in size
Breast density may decrease as breast tissue decreases and fat increases
Breasts have more fat than breast tissue after menopause
Lower breast density makes it easier to read a woman's screening mammograms after menopause
Benign breast disorder
Any non cancerous breast abnormality
Fibrocystic breast changes
Benign breast disease (BBD) representing a variety of changes in the glandular and structural tissues of the breast
Nipple discharge characteristics
Bilateral; upper outer quadrant
Round, smooth, several lesions, cyclic, palpable
Fibroadenomas
Common benign solid breast tumors that occur in about 25% of all women and account for up to half of all breast biopsies
Fibroadenoma characteristics
Unilateral; nipple area or upper outer quadrant
Round, firm, movable, palpable, rubber, well delineated single lesion
Hyperplasia of the breast
Overgrowth of the cells
Ductal hyperplasia is an overgrowth of the cells that line the ducts
Lobular hyperplasia is an overgrowth of cell lining the milk glands (lobules)
Usual hyperplasia has cells that look very close to normal
Atypical hyperplasia has more distorted cells
Hypoplasia of the breast
Also known as insufficient glandular tissue or IGT, a very uncommon condition that can cause low or no milk production
Signs of breast hypoplasia
Narrow, widely spaced breasts
Areolas appear swollen or puffy
Asymmetrical breasts, where one is much larger than the other
Breasts do not grow or change during pregnancy, and milk never "comes in" around 3 days after giving birth
Risk factors for breast hypoplasia
Genetics - Hormonal Imbalances
Low Body Fat; Poor nutrition
Medications
Turner syndrome
Poland syndrome
Mastitis
Infection or inflammation of the connective tissue in the breast that occurs primarily in lactating or engorged women
Types of mastitis

Redness: triangle- or wedge-shaped pattern
A lump or thickening in the breast
Fever
Flu-like symptoms - body aches or chills
Tiredness

Amenorrhea
The absence of menses during the reproductive years, normal in prepubertal, pregnant, postpartum, and postmenopausal females
Dysmenorrhea
Painful menstruation, may affect more than half of menstruating women
Premenstrual syndrome (PMS)
A constellation of recurrent symptoms that occur during the luteal phase or last half of the menstrual cycle and resolve with the onset of menstruation
Premenstrual dysphoric disorder (PMDD)
A more severe variant of PMS affecting 3% to 6% of premenopausal women, markedly interferes with work, school, social activities, and relationships with others
Endometriosis
One of the most common gynecologic diseases, affecting more than 6 million women in the United States, about 10% of the adult women population, bits of functioning endometrial tissue are located outside of their normal site, the uterine cavity
Treatment for endometriosis
Non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics
Hormonal medicines like GnRH-analogues and contraceptive methods
Surgery
Infertility
The inability to conceive a child after 1 year of regular sexual intercourse unprotected by contraception
Risk factors for infertility in women

Abortion
The expulsion of an embryo or fetus before it is viable, can be a medical or surgical procedure, the purpose is to terminate a pregnancy

Enterocele
The small intestine bulges through the posterior vaginal wall (especially common when straining)
