A member asked:
Are all breast lesions showing enhancement with wash out seen on breast mri malignant?
4 doctors weighed in across 2 answers
No: Radiologists say that one of the disadvantages of breast MRI is that its specificity appears is moderate (not high), although the specificity (specificity = % of abnormal lesions that are actually cancer) has been hard to determine. Published reports give specificity values of 37% to 97%, depending on the selection of both the MRI technique and the criteria for determining cancer.

No.: There are benign lesions which enhance and demonstrate washout - , for example, a normal lymph node in the breast or fat necrosis which may be caused by trauma to the breast or breast surgery. A biopsy may be required to prove that the lesion is not malignant.
