Stages of Cancer A pathology report is a medical document that gives information about a diagnosis, such as cancer. To test for the disease, a sample of your suspicious tissue is sent to a lab. A doctor called a pathologist studies it under a microscope.
The pathologist sends a pathology report to the doctor within 10 days after the biopsy or surgery is performed. Pathology reports are written in technical medical language.
Diagnosis (Summary): The final diagnosis is the section where the pathologist concludes the information from the entire pathology report into a concise pathologic diagnosis. It includes the tumor type and cell of origin.
This information is known as the gross description. A pathologist is a doctor who does this examination and writes the pathology report.

A pathology report is a document that contains the diagnosis determined by examining cells and tissues under a microscope. The report may also contain information about the size, shape, and appearance of a specimen as it looks to the naked eye. This information is known as the gross description.
During a biopsy, a doctor removes a small amount of tissue from the area of the body in question so it can be examined by a pathologist. For most types of cancer, a biopsy is the only way to make a definitive cancer diagnosis.
A biopsy report describes the findings of a specimen. It contains the following information: Gross description. A gross description describes how it looks to the naked eye and where the biopsy was taken from.
Interpreting pathology test results The treating practitioner is the most appropriate and qualified person to explain and discuss pathology test results. This is because tests represent just one of the many factors that are considered in reaching a diagnosis and planning treatment.
Determination of the cause or causes of an illness by examining fluids and tissues from the patient before or after death. The examination may be performed on blood, plasma, microscopic tissue samples, or gross specimens. See: autopsy; pathology.
The reported frequency of anatomic pathologic errors ranges from 1% to 43% of all specimens, regardless of origin and disease, he said. The error rate for oncology is 1% to 5%.
A histopathology report describes the tissue that the pathologist examined. It can identify features of what cancer looks like under the microscope. A histopathology report is also sometimes called a biopsy report or a pathology report.
The American Osteopathic Board of Pathology also recognizes four primary specialties: anatomic pathology, dermatopathology, forensic pathology, and laboratory medicine. Pathologists may pursue specialised fellowship training within one or more subspecialties of either anatomical or clinical pathology.
A biopsy is a medical procedure that involves taking a small sample of tissue so that it can be examined under a microscope. A tissue sample can be taken from almost anywhere on, or in the body, including the skin, stomach, kidneys, liver and lungs.
Carcinomas. A carcinoma begins in the skin or the tissue that covers the surface of internal organs and glands. Carcinomas usually form solid tumors. They are the most common type of cancer. Examples of carcinomas include prostate cancer, breast cancer, lung cancer, and colorectal cancer.
Biopsies are frequently used to diagnose cancer, but they can help identify other conditions such as infections and inflammatory and autoimmune disorders. They may also be done to match organ tissue before a transplant and to look for signs of organ rejection following a transplant.

Grade: The pathologist compares the cancer cells to healthy cells. There are different scales for specific cancers. A tumor grade reflects how likely it is to grow and spread. In general, this is what those grades mean: Grade 1: Low grade, or well-differentiated: The cells look a little different than regular cells.
Grade: The pathologist compares the cancer cells to healthy cells. There are different scales for specific cancers. A tumor grade reflects how likely it is to grow and spread. In general, this is what those grades mean: 1 Grade 1: Low grade, or well-differentiated: The cells look a little different than regular cells. They aren’t growing quickly. 2 Grade 2: Moderate grade, or moderately differentiated: They don’t look like normal cells. They’re growing faster than normal. 3 Grade 3: High grade, or poorly differentiated: The cells look very different than normal cells. They’re growing or spreading fast.
Identifying information: This has your name, birth date, and medical record number. It also lists contact information for your doctor, the pathologist and lab where the sample was tested.
They’re positive if they have cancer and negative if they don’t. Mitotic rate: This is a measure of how quickly cancerous cells are dividing. To get this number, the pathologist usually counts the number of dividing cells in a certain amount of tissue. The mitotic rate is often used to find what stage the cancer is in.
Cancers that spread are called invasive. Metastatic cancer is when the disease spreads to another part of the body from where it started.
These are different types of ductal carcinoma. Tubular, mucinous, and cribriform carcinomas are types of well-differentiated cancers with typically a better prognosis. Micropapillary carcinomas are associated with a worse prognosis. However, a definite diagnosis of these types of cancer cannot be established on needle biopsy, since some tumors may have mixed features. Only if most of the tumor shows these features, which can only be done once the entire tumor is removed on lumpectomy or mastectomy, can these types of cancer be definitively diagnosed.
The two major patterns seen in breast carcinoma are ductal carcinoma or lobular carcinoma. In some cases, the tumor can have features of both and are called mixed ductal and lobular carcinoma. In general, there is not a significant different prognosis between invasive lobular and invasive ductal adenocarcinoma of the breast.
The pathologist typically will measure the greatest dimension of the tumor as seen under the microscope or by gross (naked eye) examination (if visible). Not all cancers on needle biopsy are given a measurement, as the more accurate measurement will be done on the subsequent excision (lumpectomy or mastectomy).
If carcinoma extends to the ink, it indicates that it may not have been completely removed. The management of "invasive carcinoma", "intraductal carcinoma" (pre-cancer), "in-situ lobular carcinoma" (pre-cancer), "atypical duct hyperplasia" (early pre-cancer), or "atypical lobular hyperplasia (early pre-cancer)" at a margin is best discussed with your treating physician.
Tumors cells can break into small vessels seen under the microscope which is called "vascular" or "lymphovascular invasion". The presence of tumor in vessels is associated with an increased risk that the tumor has spread outside the breast, although this does not always occur. D2-40 and CD34 are special tests that the pathologist may do to help identify vascular invasion. These tests are not necessary in every case. If your report does not mention vascular or lymphovascular invasion, it means it is not present. Even with vascular invasion your cancer could still be very curable depending on other factors. How this finding will affect your specific treatment is best discussed with your treating doctor.
The stage of the tumor is a measurement of its extent both in the breast and whether there is any spread beyond the breast. A stage is typically not given for a needle biopsy specimen as the pathologist does not have the entire tumor to evaluate. For lumpectomy specimens, a stage is usually reported that takes into consideration the size of the tumor, which is indicated by "pT" followed by numbers and letters to indicate its size. The larger the number, the larger the tumor size. "pN" followed by numbers and letters indicate if and the extent of spread to any lymph nodes (see below) that may have been removed with the specimen. "pMx" means that the pathologist cannot determine whether there is spread to distant sites (ie. lung, liver, bone) because this must be determined by radiographic studies. How the stage of your tumor will affect your therapy is best discussed with your treating physician.
D2-40 and CD34 are special tests that the pathologist may do to help identify vascular invasion. These tests are not necessary in every case. If your report does not mention vascular or lymphovascular invasion, it means it is not present.
A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. A noncancerous, or benign tumor, means the tumor can grow but will not spread.
This happens because the features of a tumor can sometimes vary in different areas. Your doctor will consider all of the reports to develop a treatment plan specific to you.
Reading a Pathology Report. A pathology report is a medical document written by a pathologist. A pathologist is a doctor who diagnoses disease by: The report gives a diagnosis based on the pathologist’s examination of a sample of tissue taken from the patient’s tumor. This sample of tissue, called a specimen, is removed during a biopsy.
Tumors with fewer dividing cells are usually low grade. Tumor margin. Another important factor is whether there are cancer cells at the margins, or edges, of the biopsy sample. A “positive” or “involved” margin means there are cancer cells in the margin.
Synoptic report, or summary. When the tumor was removed, the pathologist will include a summary. This lists the most important results in a table. These are the items considered most important in determining a person’s treatment options and chance of recovery.
A noncancerous, or benign tumor, means the tumor can grow but will not spread. Other specific details about the tumor’s features. This information helps your doctor figure out the best treatment options. Your doctor will receive these test results as they become available.
Grade. Grade describes how the cancer cells look compared with healthy cells. In general, the pathologist is looking for differences in the size, shape, and staining features of the cells. A tumor with cells that look more like healthy cells is called "low grade" or "well differentiated.".
Microscopic Description: In the microscopic description, the pathologist describes how the cells of the tissue sample appear under a microscope. Specific attributes that the pathologist may look for and describe may include cell structure, tumor margins, vascular invasion, depth of invasion and pathologic stage.
The pathologist then writes a pathology report summarizing his or her findings.
Most cancer patients will undergo a biopsy or other procedure to remove a sample of tissue for examination by a pathologist in order to diagnose their disease. There are a variety of methods used to obtain samples, including a typical biopsy, fine needle aspiration, or a biopsy with the use of an endoscope.
A pathologist is a physician specializing in the diagnosis of disease based on examination of tissues and fluids removed from the body. Upon examination, the pathologist determines if the tissue sample contains normal, pre-cancerous or cancerous cells and then writes a report with his or her findings.
The histologic grade helps the pathologist identify the type of tumor. The grade may be described numerically with the Scarff-Bloom-Richardson system (1-3) or as well-differentiated, moderately-differentiated or poorly differentiated. Grade 1 or well-differentiated: Cells appear normal and are not growing rapidly.
Your primary doctor should be able to address specific questions you have about your pathology report; however, it is helpful to have a basic understanding of what the pathologist is looking for. The structure and information provided in your pathology report may vary, but the following sections are usually included.
The method used to gain a tissue sample depends on the type of mass and location in the body. Doctors are increasingly using "liquid" biopsies to evaluate cancer which are easily collected from the blood and are non-invasive. Liquid biopsies are replacing the need to collect tissue in many situations.
Skin samples taken by a biopsy or surgical excision are typically sent to a pathology laboratory for microscopic examination and diagnosis. A pathology report is issued by a pathologist or dermatopathologist.
The following information (in purple) is from an actual melanoma pathology report. Not all pathology reports will have all of these details, but this sample report should help you decipher yours.
Many standardized procedures are performed before a diagnosis can be rendered. After the patient’s tissue sample is collected during either a biopsy or excision (the surgical removal of tissue), the pathologist conducts what’s known as a gross examination, performed with the naked eye, rather than under a microscope.
Tan. “A tumor that lines a surface, such as the skin or the GI tract, is carcinoma ,” he explains. “If the tumor originates from soft tissue like muscle, it’s sarcoma.
The pathologist is a medical doctor specializing in diagnosing disease by examining organs, tissues, cells and bodily fluids.
The sectioned samples are preserved for future testing, which may be necessary if medical advancements lead to the discovery of a new tumor marker or a new treatment, for example, or if a duplicate slide is needed for the patient to use in seeking a second opinion.
Observations noted in the gross examination include the sample’s appearance and characteristics, such as size (typically documented in centimeters), texture (whether it is hard or soft, smooth or lumpy) and color. Gross examinations help determine accurate diagnoses because certain tumors have specific characteristics.
When reading a pathology report, Dr. Tan suggests paying close attention to the tumor type, grade and stage, and he recommends getting a second opinion if you’ve been diagnosed with cancer. “It’s always better to have a second pathologist review the diagnosis,” he says.
