Dense Breasts/Anxiety Returns

parenchyma are the parts of an organ that are essential to its functioning, as opposed to things like a capsule that encompasses an organ.  So, I would assume the parenchyma of the breast would be the lobules and ducts, as opposed to the more fatty parts of the breast.

This site claims "Regardless of breast density, if a breast cancer is present, breast MRI can detect it greater than 95% of the time, while mammography can detect cancer approximately 80-90% of the time." http://www.mgh.org/nuclear/breast_MRI.html

In this study, it sounds like fat necrosis (which is benign) can look like a malignancy under MRI. http://www.ncbi.nlm.nih.gov/pubmed/12140154

I can't find studies that look at breast lumps with MRIs specifically.

I hate it when my  LCIS sisters have to go through this!
