firgg
Mastoplasia
Ropy thickening of breast tissue often in upper outer quadrant persistent thru menstrual cycle
Galactorrhea
Abnormal breast discharge not necessarily milk
Gynecomastia
Swelling of breast tissue in boys or men caused by an imbalance of horomones estrogen and testosterone
Cooper’s ligaments
Fibrous septa that extend from skin to underlying pectoralis fasciae forming triangular lobules radially around the nipple, often when invaded by breast cause dimpling of the skin
Lymphatic drainage of the breast
- 75% axillary
- remaining 25% to internal mammary vessels and direct lymphatics to mediastinum
Breast tenderness 3-4 days prior to menses is due to….
….increased levels of estrogen and progesterone that cause cell proliferation and water retention
Where do most breast cancers start?
Terminal lobular ductal units composed of myoepithelial and epithelial cells
3D breast digitial tomosynthesis/ 3D mammography
A CT like type of digital mammogram that is highly detailed and views breast in slices, unfortunately still considered expeerimental by many insurance companies
When a woman has implants, what kind of breast exam does she need?
Diagnostic for any remaining tissue in the implant
Proper steps to take for all mammography screening
- Screening mammo
- If abnormal, diagnostic mammo
- Breast ultrasound
- Biopsy
Breast Imaging Reporting and Database System (BI-RADS) scale
0 - wasn’t diagnostic due to external error
1 - continue regular screening if >40yrs, its negative
2 - benign, continue regular screening if >40yrs
3 - likely benign, recommend 6 month follow up
4 - suspicious abnormality, do a biopsy just to be safe
5 - likely cancer
6 - def cancer
Breast cancer screening is unneccisary in patients….
…75 or older, or bilateral mastectomy
Of the 2 screening guideline bodies, ACS and USPSTF, which do we follow regarding breast cancer?
ACS
Severe mastodynia treatment
- Tamoxifen (anti estrogen)
- Goserelin (push into menopause)
Topical mastodynia treatment
Diclofenac (solaraze)
Fibrocystic breast changes
General term for benign breast changes that may include mobile lumps or pain but entail poorly defined symptoms and etiology
Diagnostic testing for fibrocysstic changes of the breast
Image directed core needle biopsy - remove a sample of breast tissue
Galactocele
Well circumscribed round milk filled cyst usually found in the central breast, thought to be due to spoiled milk buildup, treated easily with aspiration
Fibroadenoma
Firm freely mobile solid benign solitary breast mass 2nd most common tumor in the breast
What age group is firboadenoma most common?
Woen 15-35, arises in late teens and druing reproductive years
Phyllodes tumor
Rare rapidly growing bulky tumors that distort the breast, may ulcerate thru skin due to pressure necrosis, wide exicsion required unless metastasis has occurred
Intraductal papilloma
Benign growth within the ductal system that presents as bloody nipple discharge (that isn’t cancer), most common cause of unilateral nipple discharge***, relieved upon expression
Diagnosis for an intraductal papilloma
Ductogram
Fat necrosis
Bruised or dead tissue within the breast often due to trauma forming stellate lesions
