Presentation
Routine screening. Patient is asymptomatic.
Patient Data
There is a subtle spiculated mass in the left breast, upper inner quadrant. It is more easily appreciated on the CC view. A
This is a zoomed in image of the left CC contact mammogram shown above - making allowances that we are no longer on the high resolution mammo screens!
Dedicated workup views confirm that the lesion persists following spot compression.
Spiculated mass was found on ultrasound, measuring only 3mm.
An ultrasound guided biopsy of the sonographic lesion was performed. Clip inserted at the biopsy site confirms that this corresponds to the spiculated mass seen on mammogram.
Core biopsy pathology result:
Grade 1 invasive ductal carcinoma.
Case Discussion
This is a small, subtle low grade cancer detected at screening mammography as a spiculate mass.
The ability to detect small cancers is crucial in breast cancer screening, as cancer size is an independent risk factor for overall and recurrence-free survival.
