Figure legend: Examples of invasive cancers with various levels of ER expression. Panel
A (50×) and Panel B (200×) are from a case that was strongly and uniformly positive
(90-100% cells staining, strong intensity). Panel C (50×) and Panel D (200×) are from a
case with weak-moderate intensity but almost uniformly positive (70-80% cells staining,
weak- moderate intensity).
