The fact epithelial hyperplasia(a component of fibrocystc disease of breast) is related with the breast carcinoma has been well known.
But this relation appears to have difference according to the type of breast carcinoma.
In case of DCIS or DCIS with stromal invasion, there appears to be deep relation with epithelial hyperplasia.
On the other hand, there appears to be no particular relation between epithelial hyperplasia and invasive carcinoma without DCIS.
Therefore, in nomenclature, I propose that the so-called invasive carcinoma must differentiate into DCIS with stromal invasion and pure infiltrating carinoma according to the presence of DCIS or not.
