IHC uses antibodies to identify specific antigens on the surface of cancer cells. IHC can often be used to: Determine where the cancer started >> Go To The Portal
A doctor called a pathologist studies it under a microscope. They may also do tests to get more information. These findings go into your pathology report. It includes your diagnosis, if and how much your cancer has spread, and other details.

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.
By looking at and testing the tumor tissue, the pathologist is able to find out: If the tissue is noncancerous or cancerous. 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. Other specific details about the tumor’s features.
This information is known as the gross description. A pathologist is a doctor who does this examination and writes the pathology report. Pathology reports play an important role in cancer diagnosis and staging (describing the extent of cancer within the body, especially whether it has spread), which helps determine treatment options.
A pathology report indicates whether cancer has spread to nearby lymph nodes and other organs. Mitotic rate: This notes how quickly cancer cells are dividing.
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.
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. They may also do tests to get more information.
The specimen is analyzed by a pathologist, who then writes up a report for the medical provider who has either ordered the report or performed the procedure. Pathology reports are used by your medical provider to determine a diagnosis or treatment plan for a specific health condition or disease.
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.
Pathology is a branch of medical science that involves the study and diagnosis of disease through the examination of surgically removed organs, tissues (biopsy samples), bodily fluids, and in some cases the whole body (autopsy).
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.
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 laboratory report is a report of the analysis or examination of body specimens.

Tumor margin: For the pathology sample, your surgeon took out an extra area of normal tissue that surrounds the tumor. This is called the margin. The pathologist will study this area to see if it’s free of cancer cells. There are three possible results:
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.
Microscopic description: The pathologist slices the tissue into thin layers, puts them on slides, stains them with dye, and takes a detailed look with a microscope. The pathologist notes what the cancer cells look like, how they compare to normal cells, and whether they’ve spread into nearby tissue.
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.
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.
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.
Lymph nodes are tiny, bean-shaped organs that help fight disease. A lymph node is called “positive” when it contains cancer and “negative” when it does not. A tumor that has grown into blood or lymph vessels is more likely to have spread elsewhere. If the pathologist sees this, he or she will include it in the report.
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.
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.
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. Learn about the various types of biopsies.
When your breast was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. The pathology report tells your treating doctor the diagnosis in each of the samples to help manage your care. This FAQsheet is designed to help you understand the medical language used in the pathology report.
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.
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.
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.
If your report does not mention E-cadherin, it means that this test was not necessary to make the distinction. 5.
1. What is "carcinoma" or "adenocarcinoma"? Breast carcinoma or adenocarcinoma is synonymous with breast cancer which is malignant, although can be curable when caught early.
When looking at the cancer cells under the microscope, the pathologist looks for certain features that can help predict how likely the cancer is to grow and spread. These features include the arrangement of the cells in relation to each other, whether they form tubules (gland formation), how closely they resemble normal breast cells (nuclear grade), and how many of the cancer cells are in the process of dividing (mitotic count). These features taken together determine how differentiated the cancer is (and its grade – see below).
When your breast was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. The pathologist sends your doctor a report that gives a diagnosis for each sample taken.
Breast carcinomas are often divided into 2 main types: invasive ductal carcinoma and invasive lobular carcinoma, based on how they look under the microscope. In some cases, the tumor can have features of both and is called a mixed ductal and lobular carcinoma.
Carcinoma is a term used to describe a cancer that begins in the lining layer (epithelial cells) of organs like the breast. Nearly all breast cancers are carcinomas. Most are the type of carcinoma that starts in glandular tissue, which are called adenocarcinomas.
All breast cancers and pre-cancers, with the exception of lobular carcinoma in situ (LCIS), should be tested for these hormone receptors when they have the breast biopsy or surgery.
If breast cancer spreads, it often goes first to the nearby lymph nodes under the arm (called axillary lymph nodes ). If any of your underarm lymph nodes were enlarged (found either by physical exam or with an imaging test like ultrasound or mammogram), they may be biopsied at the same time as your breast tumor. One way to do this is by using a needle to get a sample of cells from the lymph node. The cells will be checked to see if they contain cancer and if so, whether the cancer is ductal or lobular carcinoma.
Both invasive ductal carcinomas and invasive lobular carcinomas arise from the cells lining the ducts and lobules in the breast. In general, invasive lobular and invasive ductal carcinomas of the breast aren’t treated differently.
Learn about the possible terms you might see on a breast pathology report, including breast carcinoma (cancer), lobular carcinoma (LCIS), ductal carcinoma (DCIS), atypical hyperplasia, and various benign breast conditions.
A lung pathology report may include information about findings that are not cancer, such as granulomas, scarring, or inflammation. If cancer is found, it may also describe a type of cancer using specific terms. Learn how to interpret your lung pathology report here.

The pathologist is a medical doctor specializing in diagnosing disease by examining organs, tissues, cells and bodily fluids.
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.
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.
Identifying tumor type is key because tumors behave differently. “A treatment for lymphoma won’t work on a carcinoma,” says Dr. Tan. “Sarcoma usually doesn’t metastasize to lymph nodes, but carcinoma often does, and that’s important. One type of cancer requires a lymph node dissection, and another doesn’t.” And some tumor types, such as breast and lung cancers, require additional analysis because they may benefit from targeted therapies. Hormonal markers in breast tumors help identify which drugs may have the greatest impact, for example. “A breast cancer patient with an estrogen receptor-positive tumor typically gets tamoxifen, but a patient whose cancer is HER2-positive would get trastuzumab (Herceptin ® ), and if none of the slides show hormonal markers, the patient will typically get chemotherapy,” says Dr. Tan.
Once the pathologist has examined all the tissue samples macroscopically (with the naked eye) and microscopically, and has graded them, he or she stages the cancer, assigning it a number from 0 (zero) to IV, with stage 0 indicating the cancer has not spread from its original location and stage IV indicating advanced disease.
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.

The pathology report tells your physician the diagnosis in each of your samples, and helps to manage your care. This FAQ sheet is designed to help you understand the medical language used in the pathology report. If your doctor says that you have cancer in your esophagus, it means that a pathologist, looking at the tissue samples your doctor took, found cancer in the tissue. A cancer diagnosis means that you have a tumor that is able to spread to other parts of your body.
The lining of the esophagus and stomach is known as the "mucosa." Most of the esophagus is lined by a tough covering called "squamous mucosa." Squamous mucosa is made up of many layers of flat cells that are similar to skin cells, but are on the inside of the esophagus. Goblet cells make up part of the normal lining in the intestines, but not in the esophagus. When goblet cells develop in a place where they are not supposed to be, this is called "intestinal metaplasia." When intestinal metaplasia occurs in the esophagus, it is called "Barrett's esophagus" Adenocarcinomas can start in Barrett's Esophagus or they can start in the part of the stomach just next to the esophagus. Squamous carcinomas arise from the squamous lining (mucosa) of the esophagus. In most cases of squamous carcinoma, the squamous lining is abnormal where the cancer starts.
Squamous carcinoma of the esophagus is a type of cancer (tumor) whose cells resemble the cells that make up the normal lining of the esophagus (see FAQ#3). Squamous carcinoma usually arises in a setting of smoking, prior injury to the esophagus from radiation, chemical ulceration, or alcohol abuse. Squamous carcinoma is not associated ...

Grade is one of the many factors that helps determine how aggressive a given cancer is. Poorly differentiated cancers tend to be more aggressive. However, other factors in addition to grade, such as how far the cancer has spread (which cannot be determined on the biopsy) also affect the prognosis (how likely a person will survive the cancer).
A pathologist is a doctor who diagnoses diseases by looking at tissue from the body. Samples of your melanoma tissue, removed during surgery or biopsy, will be sent to them for review. The pathology report is a result of their findings. This report contains important information about the tumor which is used to make treatment decisions.
Ulceration is thought to reflect rapid tumor growth, which leads to the death of cells in the center of the melanoma. Regression: Regression is described as being present or absent. If it is present, the extent of regression is identified.
Vertical Growth Phase (VGP): The melanoma is described as having VGP present or absent. If present, it is an indication that the melanoma is growing vertically or deeper into the tissues. VGP melanomas are invasive and have a potential to metastasize (spread to other areas).
If present, RGP indicates that the melanoma is growing horizontally or radially within a single plane of skin layer, meaning it is growing outward (horizontally), across the skin.
Ulceration: Ulceration is the sloughing of dead tissue. This can sometimes occur in the center of a melanoma lesion. The presence of ulceration is incorporated into the staging classification of a melanoma. Ulceration is thought to reflect rapid tumor growth, which leads to the death of cells in the center of the melanoma.
If present, it means that the melanoma cells have invaded the blood or lymph system.
Tumor-Infiltrating Lymphocytes (TILs): TILs describe the patient's immune response to the melanoma. When the pathologist examines the melanoma under the microscope, he/she looks for the number of lymphocytes (white blood cells) within the lesion. This response, or TILs, is usually described as "brisk", "non-brisk", or "absent", although occasionally as "mild" or "moderate". TILs indicate the immune system's ability to recognize the melanoma cells as abnormal.
