Contents
Gross examination
Selection and trimming
- Determine total specimen size. Optionally, determine weight[1]
- Ink margins.Template:Ink note If sample orientations are marked, use different colors for different directions.[1]
- Palpate specimen for masses. Compare with radiograph if available[1]
- Make 3-4 mm thick slices.[1]
- Submit:[1]
- Entire specimen if it can fit in 3-5 slices.
- If larger, 1 slice per cm of tumor (minimum of 3 slices of tumor), including both center and periphery of tumor.
- Additional suspicious areas, including those indicated by mammography

Report
- Size of original tissue sample, preferably in 3 dimensions.

Microscopic evaluation

- Tumor size
- Tumor type, see most common conditions below.
- Distance from excision margin
