3D breast tomosynthesis
breast tomo
2018, the american cancer society estimates that ________ women will be diagnosed with
invasive breast cancer - CORRECT ANSWER - 266,120
an additional ______ cases of in-situ breast cancer will be diagnosed - CORRECT
ANSWER - 63,960 (most common cancer diagnosed in women)
Breast cancer is the ____ leading cause of cancer death in women - CORRECT
ANSWER - 2nd
Once a women of average risk reaches the age of 40, she should begin _____ screening mammo
and continue for as long as she is in good health - CORRECT ANSWER - annual
since 1990, breast cancer mortality rate has _____ by 35% - CORRECT ANSWER -
decreased, due to improved breast cancer treatment and early detection by annual screening
mammogram.
Most significant clinical trail and the largest study of digital mammo? - CORRECT
ANSWER - Digital mammography imaging screening trial (DMIST)
, Purpose of the DMIST study? - CORRECT ANSWER - to evaluate the diagnostic
accuracy of digital mammo vs analog film in asymptomatic patients.
DMIST study found that Full-field digital mammo (FFDM) is a better imaging tool when
compared to film ammo in certain subsets of women; - CORRECT ANSWER - women
under 50
women with very dense glandular breast tissue
women who are pre-menopausal or peri-menopausal
Breast tissue composition - CORRECT ANSWER - the breasts are almost entirely fatty
there are scattered areas of fibroglandular density
the breast are heterogeneously dense, which may obscure small masses
the breast are extremely dense, which lowers the sensitivity of mammo
sensitivity - CORRECT ANSWER - Correctly identifies those women who have breast
cancer on screening mammo. When sensitivity is high, very few cases of cancer are missed on
mammo. however, this means that some healthy women will be misidentified as having cancer
(false positive result)
specificity - CORRECT ANSWER - correctly identifies those women who do not have
cancer on the screening mammo. When specificity is high, there are fewer false positives result
but more cases of true cancer are missed.
mammo screening of women with dense breast tissue is complicated by 3 issues; - CORRECT
ANSWER - dense tissue can mask cancers and reduce the sensitivity of mammography by
tissue overlap
all increased risk of developing breast cancer in women with dense breast tissue
all increased risk of developing more aggressive breast cancer with dense breast tissue
estimated that women with dense breasts are 4-6 times more liekly to develop breast cancer than
women with fatty tissue - CORRECT ANSWER - as breast tissue density increases, it
becomes more difficult to distinguish masses from tissue
