Breast + Endocrine Flashcards
What age does breast screening happen in the UK?
what do they get
- Between 50 and 70
- every 3 years
- can be extended from 57 to 73
- they get a mammogram in 4 standard views and in 2 views of each breast
Identify the views in this mammograph and the outer and inner quadrants
- the top two images are the mediolateral oblique views the upper being on the top of the image close to the armpit
- the bottom two images are craniocaudal views and the outer being at the top of the image
What further investigations can be done to assess calcification seen in the breast?
- Further Mammographic views
- True lateral: allows you to see a benign calcification that settles down → “tea cupping”
- Magnification view: extra paddle over areas of calcification to see the type of calcification and to see if it is truly ductal or benign
- Ultrasound
- looks for massive to see if there is an invasive component
- Examination
- Stereotactic biopsy → using mammography equipment for targeting
- take an X-ray of the sample as well
What views do mammograms come in?
- Craniocaudal (top to bottom)
- Mediolateral oblique (up towards the armpit)
