Is fat included included in "benign breast tissue" on pathology?

Likely yes,,: Fat is a major part of breast tissue as it surrounds it and may help provide nutrients that help make breast milk, etc.. If a report says "benign breast tissue" it likely means that normal tissue is seen. Fat is part of that normal tissue. Moreover, it indicates that there isn't anything wrong with that tissue seen at that time. You can also discuss this with your dr. To be sure. Good luck.

Possibly: "benign breast tissue" is a general diagnostic category which indicates that there is no cancer or precancerous findings in the biopsy. Fat can be a component of this, as can normal breast lobules or ducts, or benign conditions such as fibrocystic disease.

Yes: The breast is made up of breast parenchyma (the lobules and ducts that produce milk) and adipose tissue (fat). As you age, the proportion of the breast that is fat increases. Essentially all breast biopsies will have fat in them and this is not reported separately by the pathologist as it is a part of the normal breast.

Yes: Fatty tissue (adipose tissue) is considered benign breast tissue. Benign breast tissue includes all the following: fibrocystic disease, florid hyperplasia, fibrous mastopathy, apocrine metaplasia, fibroadenoma, and even benign calcification.
