A pathology report is the written summary from a pathologist who examined tissue, cells, or fluid from a biopsy or surgery. For many cancers, it is one of the most important documents for a second opinion because it helps define the diagnosis and can influence treatment.
Pathology reports can be technical. You do not need to understand every word, but knowing the major sections can help you ask better questions.
What the report may include
Depending on the cancer type, a pathology report may describe:
- The cancer type or tumor name
- Whether the sample is benign, pre-cancerous, invasive, or metastatic
- Tumor grade, which describes how abnormal the cells look
- Tumor size or extent in the submitted tissue
- Margins, or whether cancer cells are close to the edge of removed tissue
- Lymph node findings
- Receptor status, such as ER, PR, or HER2 in breast cancer
- Biomarker, molecular, or genetic test results
- Special stains or additional testing
Diagnosis vs grade vs stage
Diagnosis names the cancer. Grade describes how abnormal the cancer cells look under the microscope. Stage describes how much cancer is in the body and whether it has spread. These are related but not the same.
A pathology report may contain some staging information, but staging often also depends on imaging, exam findings, surgery, and other tests.
Why another pathology review can matter
In some cases, another pathology team may review the slides to confirm the cancer type, grade, margins, or biomarker results. This can be especially helpful for rare cancers, unusual findings, or major treatment decisions.
Questions to ask
- Is the diagnosis final or are more tests pending?
- What is the cancer type and grade?
- Are margins or lymph nodes involved?
- Were biomarkers or molecular tests done?
- Would a pathology slide review change treatment planning?
