In addition to what everyone else said, they went out of their way to use the word "irregular" TWICE. Maybe simple-minded of me, but as far as I understand benign shtuff is rarely irregular.

liverdietrying  There is not enough information in the question stem to determine what kind of cancer it is. You would need a biopsy and histology information to determine that. However, this is definitely not DCIS since there *is* a mass. DCIS usually just shows up as small microcalcifications on XR (I’d google an image so you can see it). All the words they use here describe an invasive cancerous scary mass -- what kind of cancer can’t be known until they biopsy it! +2

mnemonia  Fibrocystic changes doesn’t technically encompass sclerosing adenosis, which is the one where you would get calcifications. Cysts and fibrosis don’t usually present with calcifications. Fat necrosis I’m sure they would give history of trauma in the stem. +  
mnemonia  Calcifications = fat necrosis, sclerosing adenosis, and DCIS/IDC. Microcalcifications specifically I would venture to say is a buzzword ductal carcinoma specifically. Either way, of these 3, only cancer is an answer choice. +1

submitted by j000(5),

this is not mentioned in FA or pathoma, but according to Amboss:

In invasive ductal carcinoma, the mammography finding shows "star-shaped lesion occurs due to clustered microcalcifications of the surrounding tissue."

It is not DCIS because DCIS doesn't produce a mass It is not fibroadenoma (it is most common in women <35) It is not fibrocystic changes (premenopausal women 20-50, often bilateral, tender)

Y'all need some Amboss in your lives.

This is a benign or malignant question.

focal mass or density

irregular margins


= malignant = carcinoma
