Usual problems with ADH and underestimation of DCIS/invasive cancer. Comparison of 2 different gauge needles. Increasing size to 9 -guage gave no improvement in diagnostic accuracy.
There was no statistically significant difference between 11-gauge biopsy
and 9-gauge biopsy in underestimation of atypical ductal hyperplasia and ductal carcinoma in situ.
