Benign Disord Breast
MAMC exam 8 benign disorders of the breasts
Question | Answer |
---|---|
external components of normal breasts | skin areola nipple |
internal components of normal breasts | mammary glands 15-20 lobes axillary & internal mammary lymph nodes |
what determines breast size | adipose tissue |
lactation | milk production |
hormonal cycle associated with ovulation, menstruation, & pregnancy | prolactin progesterone estrogen |
triad of assessments for breast health | breast self-exam (BSE) clinical breast exam (CBE) mammography |
BSE | regular (monthly) systematic examination starting at age 20 regularity is key! usually 7-8 days after menses 90% of lumps found by women during BSE |
rationale for regular breast exams | majority of lumps found aren't cancerous cancerous breast lesions are treatable |
techniques for teaching BSE | inspection palpation timing of BSE |
changes in breast exam to report | changes in skin texture retraction/indentation of nipple discharge from nipple atypical fullness and/or puckering |
timing of BSE's | menstruating women - 3-8 days after end of menses post-menopausal women - first day of month or any day that's remembered |
clinical breast exam (CBE) | trained health care provider patient teaching vital inspection - same as BSE palpation - sitting or supine |
mammograms | low dose x-ray of breast in combination with a physical exam detects tumors not detectable with palpation detects tumors as small as 0.5cm annual screenings beginning at 40 |
t/f mammograms are an excellent source for screening & detection and can diagnose cancer | false, cannot diagnose cancer |
established risk factors for breast tumors | over 50 family history defective gene BRCA 1 & BRCA chronic alcohol use ethnicity nulliparity age of first full term pregnancy 1st preg. after 30 age at menopause & menarche history of breast cancer or benign proliferative lesion female cancer |
50% of women diagnosed with breast cancer demonstrated none of the identified risk factors except for ______ | age |
benign growths | fibrocystic breast condition fibroadenoma acute mastitis chronic mastitis |
fibrocystic breast disease also called | chronic cystic mastitis or mammary dysplasia |
cause of fibrocystic breast disease | unknown but related to response of breast tissue to cyclic hormone changes |
most common benign breast lesion | fibrocystic breast disease |
symptoms of fibrocystic breast disease | premenstrual pain/breast tenderness diffuse tender cysts usually occur bilaterally mobile lumps if close to skin surface deeper ones from carcinoma |
definitive diagnosis of fibrocystic breast disease from | surgical biopsy |
characteristics of fibrocystic breast disease | affects premenopausal women usually 30-50 aspiration biopsy may be required for definitive diagnosis |
interventions for fibrocystic breast disease | padded bra/good supportive bra analgesics/diuretics dietary measures danocrine/danazol hormonal contraceptives |
fibroadenoma | solid benign mass of connective tissue & glandular tissue usually occurs in late adolescence or early adulthood cause unknown but related to hormonal changes |
characteristics of fibroadenoma | growths during pregnancy shrinks after menopause grows slowly - usually single nodule, not related to menstrual cycle, not considered pre-cancerous |
assessment findings of fibroadenoma | painless, non-tender lump encapsulated, mobile firm if large, breast size asymetric |
diagnosis & treatment of fibroadenoma | US more accurate than mammogram excisional biopsy as needed |
nursing management for fibroadenoma | teach how to perform BSE wound care if excision necesary follow-up care |
acute mastitis | bacterial infection usually caused by S. aureus or streptococci |
when acute mastitis most commonly occurs | during lactation |
causes of acture mastitis | poor hygiene or infant infections |
manifestations & treatment of acute mastitis | tender/inflammed breasts obstructing milk flow warm packs, well fitting bra, ABX |
risk factors for chronic mastitis | age 30-50 obesity have had difficulty nursing inverted or cracked nipples traumatic injury increased fibrosis of tissue multiparous (multiple births, i.e. twins) |
