MALIGNANT (2) Invasive carcinomas
Tumour calcification within lymphatics
This is part 3 of some common benign causes of breast
microcalcification and some less common causes. These are new examples of the conditions in question - more
can be found on the relevant 'benign' pages elsewhere on the site and cross-links
are given frequently.
Lactational change and calcification of luminal secretions

and the calcs can show a concentric psammoma-like appearance. The following causes are recognised:
Idiopathic in the absence of a history of recent lactation
