Breast Flashcards
differences between a discrete lump + localised nodularity
discrete lump
- stands out from adjoining tissue
- has definable borders
- is measurable
name 7 factors that make a patient more likely to warrant hospital referral
- lump
- pain
- nipple discharge
- nipple retraction or distortion
- nipple eczema
- change in skin contour
- family history
2 views on mammography
mediolateral oblique view + cranio-caudal
why are breasts compressed in mammography
spread out glandular tissue of the breast, reducing overlapping structures
first line imaging in women < 35 years
ultrasound imaging
what is ultrasonography?
high frequency sound waves beamed through breast; reflections are detected + turned into images
Ultrasound appearance of:
- cysts
- cancers
cysts = transparent objects
(other benign lesions have well demarcated edges)
cancers = indistinct outlines
what is colour flow doppler ultrasound used for
Images the blood flow to lesions
what is the blood flow to malignant lesions?
have greater blood flow than benign lesions
what is the value of MRIs in breast assessment
- assess extent of invasive lobular cancers; sometimes not well seen on mammography
- optimum method for imaging breast implants
- high risk women between 35 and 50 years
What is the role of FNAC or needle core biopsy?
establish diagnosis without need for surgical excision
1-5 scale for each component of tripple assessment
1 - normal 2 - benign 3 - intermediate/probs benign 4 - suspicious 5 - malignant
2 indications for breast imaging
1) symptomatic
2) breast screening
frequency of breast screening
every 3 years from 47 to 73 years of age
management of: breast mass + localised nodularity?
clinical + imaging assessment with biopsy
investigation for presentation of galactorrhea?
- associated with: pregnancy or breastfeeding
- check prolactin levels
- investigate for pituitary tumours
