Understanding Your Biopsy Report: A Patient's Guide

Q: What is a biopsy?

A biopsy is the removal of a small tissue sample, examined under a microscope by a pathologist, to determine whether cancer is present and, if so, what type it is. It is usually the step that confirms a cancer diagnosis.

Q: What does the biopsy report actually tell my doctor?

It describes the tissue examined, whether abnormal or cancerous cells are present, the type and subtype of cancer if found, how abnormal the cells look (grade), and sometimes additional markers that guide treatment choices.

Q: What do terms like “malignant,” “benign,” and “grade” mean?

“Benign” means non-cancerous; “malignant” means cancerous. “Grade” describes how abnormal the cells look under the microscope and relates to how quickly the cancer is likely to grow — generally, lower grades tend to grow more slowly than higher grades.

Q: What is immunohistochemistry (IHC), which I sometimes see mentioned?

IHC is a specialised staining technique used to identify specific proteins on cancer cells, which helps classify the cancer more precisely and can guide treatment decisions, particularly for cancers like breast cancer where receptor status matters.

Q: Why does it sometimes take days or weeks to get biopsy results?

Tissue processing, staining, and detailed examination — sometimes including additional specialised tests like IHC — take time to do accurately. This waiting period is understandably difficult, but the time reflects thoroughness rather than delay for its own sake.

Q: Should I get a second pathology opinion?

For a significant diagnosis, a second opinion from another pathologist — sometimes called a review of slides — is a reasonable and fairly common step, particularly before major treatment decisions. Your treating doctor can help arrange this if you'd like one.

Q: What questions should I ask my doctor about my report?

Useful questions include: What type and grade is this? What stage does this suggest? Were any special markers tested, and what did they show? What do these findings mean for my treatment options?
