What is a pathology report?
A pathologist examined tissue from your biopsy or surgery under a microscope and documented exactly what they found. This report is the basis for your diagnosis and treatment plan — it is the document your whole care team relies on to decide what happens next.
The structure of a pathology report
Clinical history
Why the biopsy was done — the symptoms, findings or concerns that led your provider to take a sample.
Gross description
What the tissue looked like to the naked eye — its size, color and overall appearance before it was examined under a microscope.
Microscopic description
What the pathologist saw when they examined the cells and tissue under the microscope. This is where the detail lives.
Diagnosis
The conclusion — the pathologist’s bottom-line interpretation of everything they found. This is the most important section of the entire report.
Key pathology terms explained
Benign
Not cancerous. This is good news.
Malignant
Cancerous.
Carcinoma in situ
Abnormal cells are present but have not spread beyond where they started — a very early stage, highly treatable.
Invasive
Cancer cells have spread beyond their original location.
Margins
The edge of the removed tissue. “Clear” or “negative” margins mean no cancer cells at the edge (a good sign); “positive” margins mean cancer cells were found at the edge and more tissue may need to be removed.
Grade
How abnormal the cells look — a lower grade often means slower growing.
Stage
How far the cancer has spread (different from grade).
Atypical
Cells look unusual but not necessarily cancerous — often needs monitoring or further testing.
Hyperplasia
An increased number of cells — usually benign.
Dysplasia
Abnormal cell growth that could become cancerous over time — requires monitoring.
What to do after receiving your results
1Schedule a follow-up to discuss the results in person.
2Bring a written list of questions so nothing slips your mind.
3Consider bringing a support person with you.
4Ask for a copy of the full report for your own records.
Red flags requiring prompt follow-up
Some findings warrant a prompt call to your provider so you can talk through what they mean and what comes next. Reach out without delay if you see:
Any mention of “malignant” or “carcinoma”
“Positive margins”
“High grade”
A recommendation for “urgent” or “immediate” follow-up
If you have severe symptoms such as chest pain, trouble breathing, fainting or confusion do not wait for a callback — call 911 or go to the nearest emergency room.
