The size and location of the tumor (Tumor, T) Usually, the pathologist assigns a stage using the TNM system from the American Joint Committee on Cancer (AJCC). If the pathologist sees this, he or she will include it in the report. A tumor that has grown into blood or lymph vessels is more likely to have spread elsewhere. A lymph node is called “positive” when it contains cancer and “negative” when it does not. Lymph nodes are tiny, bean-shaped organs that help fight disease. The pathologist will also note whether the cancer has spread to nearby lymph nodes or other organs. This means that it is likely that cancerous cells are still in the body. A “positive” or “involved” margin means there are cancer cells in the margin. Another important factor is whether there are cancer cells at the margins, or edges, of the biopsy sample. Tumors with fewer dividing cells are usually low grade.
The pathologist usually notes how many cells are dividing. How quickly cells are dividing, mitotic rate. Learn more about grading for specific cancer types.
There are different methods used to assign a cancer grade for different types of cancers. A tumor with cells that look more like healthy cells is called "low grade" or "well differentiated." A tumor with cells that look less like healthy cells is called "high grade," "poorly differentiated," or "undifferentiated." In general, the lower the tumor’s grade, the better the prognosis. In general, the pathologist is looking for differences in the size, shape, and staining features of the cells. Grade describes how the cancer cells look compared with healthy cells. For invasive tumors, it is important for the pathologist to note how much the tumor has grown into nearby healthy tissue. Although noninvasive tumors do not spread, they may grow or develop into an invasive tumor in the future. Invasive tumors can spread to other parts of the body through a process called metastasis. Tumors of many types may be noninvasive (in situ, which means “in place”) or invasive. There are several factors noted in this section that affect diagnosis and treatment. It describes what the cancer cells look like when viewed under a microscope. This is the most technical section of the report. This includes the general color, weight, size, and consistency. This section describes the tissue sample or tumor as seen with the naked eye.
The pathologist’s and oncologist’s contact information, as well as the laboratory where the sample was testedĭetails about the specimen, including the type of biopsy or surgery and the type of tissue Patient's name, birth date, and other personal informationĪn individual number assigned to the patient to help identify samples But most pathology reports include the sections discussed below. Parts of a pathology reportĭifferent pathologists use different words to describe the same things. Ask your doctor to explain the results in the pathology report and what they mean. But you should expect the report to contain highly technical medical terms. You are allowed by law to receive a copy of your pathology report. The timing depends on the testing needed.

It may take a few days to a few weeks to receive the full report. Your doctor will receive these test results as they become available. This information helps your doctor figure out the best treatment options. Other specific details about the tumor’s features. A noncancerous, or benign tumor, means the tumor can grow but will not spread.
A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. If the tissue is noncancerous or cancerous. Learn about the various types of biopsies.īy looking at and testing the tumor tissue, the pathologist is able to find out: This sample of tissue, called a specimen, is removed during a biopsy. The report gives a diagnosis based on the pathologist’s examination of a sample of tissue taken from the patient’s tumor. A pathologist is a doctor who diagnoses disease by: A pathology report is a medical document written by a pathologist.
