Among lesions detected in the first episode of screening 40.6% (363 of 894) proved to be malignant, whereas 51.9% (857 of 1651) of microcalcifications assessed in subsequent screening rounds were malignant.

How many microcalcifications are cancerous?

Some radiologists consider five or more calcifications in a cluster to be possibly suspicious of an underlying cancer. However, this is not a definite cutoff number — others recommend additional testing even if there are fewer than five in a cluster.
