Yes! A biopsy report contains a wealth of important information about your breast cancer. It's one of the most important documents in your care journey.

Here's what your biopsy report typically includes:

- HER2 status — whether your cancer is HER2-positive or HER2-negative
- Hormone receptor status — estrogen receptor (ER) and progesterone receptor (PR) levels
- Cancer grade — how different the cancer cells look compared to normal cells (low, medium, or high grade)
- Cancer type — the specific kind of breast cancer cells found
- Spread — whether cancer cells show signs of growing into nearby tissue HER2 status is determined through two main tests performed on your biopsy tissue:

- IHC (Immunohistochemistry) — measures the amount of HER2 protein on the surface of cells, scored 0 to 3+
- FISH (Fluorescence in situ hybridization) — a more precise test that counts copies of the HER2 gene itself

This information helps your care team decide which treatments are most likely to work best for you. It's always a great idea to ask your oncologist to walk you through your report so nothing gets lost in translation!
