The Breast Flashcards
galactorrhea
milk production when you’re not pregnant
gynecomastia
breast development in men
BRCA
- gene that can cause breast cancer if there is a mutation in it
- normally, gene encodes protein for DNA repairnel
Fibroadenoma
- benign lump of solid tissue and well defined
- common in young women
- size doesn’t change
Fibrocystic breast disease
- cysts that form and ducts enlarge with fluid inside
- etiology: unknown
- common in 20-40 yrs
- pain, lump, size change, nipple discharge,
glandular tissue
- lubules and ducts
- exocrine glands
stromal tissue
- supporting tissue
- fat and fibrous connective tissue
mammogram
- most useful screening test for breast cancer in menopause women whose breast contain more fat and less glandular tissue
- base line age of screening 35-40 yrs
acute mastitis
- inflammation of breast
- usually due to staph infection
- swelling, pain, redness, lump
- common in women breastfeeding in first 6 months
breast carcinoma
- arises from duct-lobular unit
- age associated
- types: familiar and sporadic
risk factors of breast cancer
- prolonged estrogen exposure (no children, not breast feeding, early mecharche, late menopause)
- alcohol
- senedntary life
- white
- hormone replacement therapy
- occurs in both genders, more common women
CIS/invasive breast cancer
- CIS: 5 year survival rate is 93%
- invasive: most common diagnosis
degree of differentiation
- well differentiated: less severe, resembles normal breast tissue
- undifferentiated: more severe
sentinel lymph nodes
lymph node in breast that can be biopsied for diagnosis
lumpectomy
cut out lump in breast and tissue around it to ensure it is all taken out
Estrogen and Progesterone receptor
- tumor will have a hormone receptor on it and will cause it to grow
- drug is given to block the receptor
- if you have this it is positive
HER2 (human epidermal growth factor receptor)
-HER2+ tumors are aggressive and less responsive to hormone treatment
Triple Negative
- more difficult to treat
- No hormone receptors and no HER+
recurrent metastatic breast carcinoma
- cancer appears years after the original tumor has been removed
- treatment is focused on controlling growth, relieving symptoms, and improving quality of life
Hormone replacement therapy
there is a risk related to hormone treatment because long term use can increase risk of breast and ovarian cancer
main function of breast
milk production
what does fatty tissue look like in mammogram
dark
what does fibrous and glandular tissue look like on mammogram
white strands
what do cysts and benign tumors look like on mammogram
well circumscribed (clear)
what does a malignant tumor look like on mammogram
irregular border and frequently contains flecks of calcium
MRI
- more sensitive than x-ray
- better at detecting small carcinoma
- also detects non significant changes in breast
ultrasound
-can differentiate between solid tissue and fluid filled benign cysts
what causes gynecomastia in men?
- puberty
- medication
- loss of liver function https://www.brainscape.com/l/study?classes=18633971-10782014(metabolizes estrogen)
- can be bilateral or unilateral
