what does a duct papilloma cause

A

bloody discharge nmo lump

21
Q

what is a radial scar

A

central scar surrounded by proliferating glandular breast tissue in a stellate papttern

22
Q

RF for breast carcinoma

A

23
Q

when does breast screening occur

A

every 3 years from 47-73 mammography

24
Q

what does mammography look for

A

calcifications or mass in the breast

25
what is breast carcinoma in situ
neoplastic epithelial proliferation limited to ducts or lobules by the basement membrane
26
what is the difference between LCIS and DCIS
DCIS presents with calcifications and LCIS doesn't
27
LCIS (lobar carcinoma in situ-breast)
incidental biopsy findings no Ecadherin no microcalifications
28
what does breast DCIS put you at risk of
invasive breast ca
29
invasive breast carcinoma subtypes
mucinous tubuluar ductal lobular
30
invasive breast ca: mucinous
produce mucin which dissects into surrounding tissue
31
invasive breast ca: lobular
cellsin single file strands
32
invasive ca: tubular
well formed tubules with low grade nuclei \<1cm
33
invasive ca: ductal
can't be subclassified
34
what is the triple assessment
examination radiological exam FNA &cytology
35
when is an USS used in triple assessment
if the woman is\<35yo if older USS+ mammography
36
what is checked for at biopsy in triple assessment
histological subtrype ER/PR receptor tubule formation mitotic activity nuclear pleomorphism
37
what receptor is associated with a good prognosis in breast ca
ER/PR
38
what receptor is asociated with poor prognosis is breast ca
HER2
39
what medications are used for HER2 breast ca
herceptin trastuzumab
40
how does tamoxifen work
mixed agonist/ antagonist of oestrogen at its receptor
41
what medication is used in breast ca to reduce oestrogen
anastrazole
42
what do basal; cell like breast ca stain positive for
CK5/6/14
43
where do phyllodes tumours originate from
interlobular stroma
44
what is seen on histology of phyllodes tumour
increased cellularity mitoses
45
do phyllodes tumours metastesis
no
46
are phyllodes tumours benign
usually
