Breast cancer • MAMMOGRAM • DUCTOGRAPHY • MRI • ULTRASOUND GMA CPD 2009
Linear probe • Freq of 7.5-9MHZ
ULTRASONOGRAPHY • RT/LT • RADIAL/ANTIRADIAL • DISTANCE FROM NIPPLE;CM FN • Breast composition • Symmetry • Focal masses • ?Calcification • Axillary LN
Screening Guidelines for the Early Detection of Breast Cancer, American Cancer Society • Yearly mammograms are recommended starting at age 40. • A clinical breast exam should be part of a periodic health examination, about every 3 years for women in their 20s and 30s. Asymptomatic women aged 40 and older should continue to undergo a clinical breast exam, preferably annually*. • Beginning in their early 20s, women should be told about the benefits and limitations of breast-self examination. Women should know how their breasts normally feel and report any breast changes promptly to their health care providers. • __________ • * Beginning at age 40 years, annual CBE should be performed prior to mammography GMA CPD 2009
Usg preferred below 30yrs • Due to breast composition • Carcinogenic nature of x-rays
BENIGN FEATURES • MASS • Well defined • Smooth margins • Fatty content • CALCIFICATION • Tramline and tortuous; arterial • Smooth and round with lucent centre • Thick rod-like • Egg-shell • Pop corn • Large calcific opacity
MALIGNANT FEATURES • MASS • Spiculated margins • Ill defined • ?Architectural distortion • Skin thickening • ?Nipple retraction • ?Retraction of pectorialis muscle
CALCIFICATION • Micro calcification • Mixture of sizes and shapes • Cluster • Haphazard arrangement • Linear branching patterns
BI-RADS • Category 0 (needs additional imaging evaluation) • Category 1 (negative- nothing to comment on) • Category 2 (Benign finding) • Category 3 (Probably benign finding) • Category 4 (Suspicious abnormality) • Category 5 (Highly suggestive of malignancy) • Category 6(histologically known malignancy)
