How Long Does It Take For Stage 1 Breast Cancer To Develop Into Stage 2
It is not possible to determine exactly how long it will take for newly diagnosed breast cancer to progress from stage 1 to stage 2. It can happen within months if it is an aggressive high-grade tumor, or it can take longer. It’s important to know that stage 1 breast cancer could have already been present for a while before being detected, so it may progress quickly.
What If My Report Mentions Margins Or Ink
When an entire tumor is removed, the outside edges of the specimen are coated with ink, sometimes even with different colors of ink on different sides of the specimen. The pathologist looks at slides of the tumor under the microscope to see how close the cancer cells get to the ink . If cancer cells are touching the ink , it can mean that some cancer was left behind, and more surgery or other treatments may be needed. Sometimes, though, the surgeon has already removed more tissue to help make sure that this isnt needed.
If your pathology report shows positive margins, your doctor will talk to you about what treatment is best.

What Does It Mean If My Report Mentions Microcalcifications Or Calcifications
Microcalcifications or calcifications are calcium deposits that can be found in both non-cancerous and cancerous breast lesions. They can be seen both on mammograms and under the microscope. Because certain calcifications are found in areas containing cancer, their presence on a mammogram may lead to a biopsy of the area. Then, when the biopsy is done, the pathologist looks at the tissue removed to be sure that it contains calcifications. If the calcifications are there, the doctor knows that the biopsy sampled the correct area .
Staging And Grading Of Breast Cancer
Knowing the stage and grade of the cancer helps your doctors plan the best treatment for you.
On this page
Your specialist doctor needs certain information about the cancer to advise you on the best treatment for you. This includes:
- the stage of the cancer
- the grade of the cancer
- whether the cancer has;receptors; for hormones or a protein called HER2.
This information comes from the results of all the tests you have had, including:
- the biopsy, when the tissue was examined
- other tests that were done on the cells.
Your specialist doctor and nurse will talk to you about this. They will explain how it helps you and your doctor decide on your treatment plan.
We understand that waiting to know the stage and grade of your cancer can be a worrying time. We’re here if you need someone to talk to. You can:

Association Of Brachyury Expression With Invasiveness And Mammosphere Formation
To investigate the potential role of brachyury in the biology of breast cancer cells, brachyury gain-of-function and loss-of-function experiments were conducted. These experiments were designed to specifically evaluate whether stable overexpression of brachyury in an epithelial, noninvasive tumor cell line could impart mesenchymal-like features and whether stable silencing of brachyury in a mesenchymal, invasive tumor cell line could convey epithelial features. As shown in , stable transfection of MCF7 cells with a brachyury-encoding vector resulted in a twofold increase in brachyury expression vs control . Functionally, brachyury overexpression in MCF7 cells markedly enhanced their ability to invade the extracellular matrix in vitro , upregulated the expression of SOX2 and NANOG, key transcriptional regulators of pluripotency , and enhanced the tumor cellsâ ability to form mammospheres in culture. The number of mammospheres formed by MCF7-pBrachyury vs control cells was enhanced both in primary and secondary cultures , suggesting that MCF7-pBrachyury cells contained an increased number of cells with self-renewal capacity compared with control vector-transfected cells.
What Does It Mean If My Doctor Asks For A Special Molecular Test To Be Performed On My Specimen
Molecular tests such as Oncotype DX® and MammaPrint® may help predict the prognosis of certain breast cancers, but not all cases need these tests. If one of these tests is done, the results should be discussed with your treating doctor. The results will not affect your diagnosis, but they might affect your treatment.;

What Is Histologic Grade Or Nottingham Grade Or Elston Grade
These grades are similar to what is described in the question above about differentiation. Numbers are assigned to different features seen under the microscope and then added up to assign the grade.
- If the numbers add up to 3-5, the cancer is grade 1 .
- If they add up to 6 or 7, it means the cancer is grade 2 .
- If they add up to 8 or 9, it means the cancer is grade 3 .
What Does It Mean If In Addition To Cancer My Report Also Mentions Atypical Ductal Hyperplasia Atypical Lobular Hyperplasia Ductal Carcinoma In Situ Intraductal Carcinoma Lobular Carcinoma In Situ Or In
These are terms for certain atypical or pre-cancer changes that can sometimes be seen on biopsy that arent as serious as invasive cancer. If they are found in a needle biopsy that also shows invasive cancer, they are typically not important. They may, however, need to be removed completely as a part of treatment. If they are seen on an excisional biopsy at or near a margin , more tissue may need to be removed .

Assessment Of Lymphovascular Invasion
In this series, LVI was assessed in a consistent way using uniform methods of specimen fixation, sampling, and processing. Tumors were received fresh in the pathology laboratory and were incised immediately to ensure good fixation. LVI was assessed in the peritumoral tissue on hematoxylin and eosin -stained sections. At least 3 different tumor sections were examined from each specimen. LVI was defined as carcinoma cells present within a definite, endothelial-lined space . Only definite LVI was regarded as positive. Possible LVI was scored as negative. No attempt was made to distinguish between blood vessels and lymphatics. Recorded data did not distinguish extensive LVI from nonextensive LVI.
In addition, data on immunohistochemical detection of LVI using the lymphovascular endothelial-specific marker D2-40 were available in a series of 976 LN-negative cases. The detailed staining technique was described previously. Briefly, 1 representative wholemount section from each specimen was stained with podoplanin/D2-40 . Cases in which podoplanin/D2-40 reactivity was observed around tumor cell clusters were considered LVI IHC-positive.
What Does It Mean If My Carcinoma Has Tubular Mucinous Cribriform Or Micropapillary Features
These are different types of invasive ductal carcinoma;that can be identified under the microscope.
- Tubular, mucinous, and cribriform carcinomas are “special types” of well-differentiated cancers that often have a better prognosis than the more common type of invasive ductal carcinoma .
- Micropapillary carcinoma is a type of invasive breast carcinoma that often has a worse prognosis.
If your doctor knows that your tumor is made up of one of these special types of breast cancer, he or she may recommend different treatment.
Since some tumors are made up of more than one type, the entire tumor must be removed in order to know what types your tumor contains. A needle biopsy doesnt give enough information to guide treatment.

The Number Staging System
Breast cancer can also be divided into four number stages. We have put these into a table to make them easier to understand. You can .
This information is about stage 1 to 3 breast cancer.
Stage 1 breast cancer is when the cancer is 2cm or smaller. There may be no cancer cells in the lymph nodes in the armpit or tiny numbers of cancer cells are found. Sometimes the cancer cannot be found in the breast, but cancer cells have spread to lymph nodes in the armpit.
Stage 2 breast cancer is when the cancer is up to or bigger than 5cm. It may or may not have spread to the lymph nodes under the arm. Sometimes the cancer cannot be found in the breast. But cancer cells have spread to 1 to 3 lymph nodes in the armpit or near the breast bone.
Stage 3 breast cancer is sometimes called locally advanced breast cancer. The cancer has spread to the lymph nodes in the armpit and sometimes to other lymph nodes nearby. It may have spread to the skin of the breast or to the chest muscle. The skin may be red, swollen or have broken down. Sometimes the cancer cannot be found in the breast or is small but has spread to 4 to 9 lymph nodes in the armpit.
Stage 4 breast cancer is also called secondary or metastatic breast cancer. This is when the cancer has spread to other parts of the body, such as the bones, the liver or lungs. We have separate information about secondary breast cancer.

Examples Using The Full Staging System
Because there are so many factors that go into stage grouping for breast cancer, it’s not possible to describe here every combination that might be included in each stage. The many different possible combinations mean that two women who have the same stage of breast cancer might have different factors that make up their stage.
Here are 3 examples of how all of the factors listed above are used to determine the pathologic breast cancer stage:
What Is The Significance Of The Stage Of The Tumor
The stage of a cancer is a measurement of the extent of the tumor and its spread. The standard staging system for breast cancer uses a system known as TNM, where:
- T stands for the main tumor
- N stands for spread to nearby lymph nodes
- M stands for metastasis
If the stage is based on removal of the cancer with surgery and review by the pathologist, the letter p may appear before the T and N letters.
The T category is based on the size of the tumor and whether or not it has spread to the skin over the breast or to the chest wall under the breast. Higher T numbers mean a larger tumor and/or wider spread to tissues near the breast. Since the entire tumor must be removed to learn the T category, this information is not given for needle biopsies.
The N category indicates whether the cancer has spread to lymph nodes near the breast and, if so, how many lymph nodes are affected. Higher numbers after the N indicate more lymph node involvement by cancer. If no nearby lymph nodes were removed to be checked for cancer spread, the report may list the N category as NX, where the letter X is used to mean that the information is not available .
The M category is usually based on the results of lab and imaging tests, and is not part of the pathology report from breast cancer surgery. In a pathology report, the M category is often left off or listed as MX .

T Categories For Breast Cancer
T followed by a number from 0 to 4 describes the main tumor’s size and if it has spread to the skin or to the chest wall under the breast. Higher T numbers mean a larger tumor and/or wider spread to tissues near the breast.
TX: Primary tumor cannot be assessed.
T0: No evidence of primary tumor.
Tis: Carcinoma in situ
T1 : Tumor is 2 cm or less across.
T2: Tumor is more than 2 cm but not more than 5 cm across.
T3: Tumor is more than 5 cm across.
T4 : Tumor of any size growing into the chest wall or skin. This includes inflammatory breast cancer.
Do I Need Genetic Counseling And Testing
Your doctor may recommend that you see a genetic counselor. Thats someone who talks to you about any history of cancer in your family to find out if you have a higher risk for getting breast cancer. For example, people of Ashkenazi Jewish heritage have a higher risk of inherited genetic changes that may cause breast cancers, including triple-negative breast cancer. The counselor may recommend that you get a genetic test.
If you have a higher risk of getting breast cancer, your doctor may talk about ways to manage your risk. You may also have a higher risk of getting other cancers such as ovarian cancer, and your family may have a higher risk. Thats something you would talk with the genetic counselor about.

Type Of Breast Cancer
Almost all breast cancers arise from glandular tissue, making them adenocarcinomas . They are further named by where they start in the breast and how they appear under the microscope. To better understand this section, you need to have some knowledge of normal breast tissue. Breast tissue is composed of lobules, which produce milk; and ducts, which carry the milk to the nipple. Breast cancer starts in a duct or a lobule and this, along with how it looks under the microscope, determines the type of breast cancer it is. The type can help guide some of the treatment choices. In addition to the type, the cancer can be non-invasive, which means it does not spread beyond the lobule or duct, or invasive, which means it has spread beyond the lobule or duct.

What Is The Life Expectancy For Each Cancer Stage
Your outlook depends on the stage of your cancer when its discovered. Cancer is staged by number, starting with 0 and going to 4. Stage 0 is the very beginning and stage 4 is the last stage, also called the metastatic stage because its when cancer has spread to other areas in the body.
Each number reflects different characteristics of your breast cancer. These include the size of the tumor and whether cancer has moved into lymph nodes or distant organs, like the lungs, bones, or brain.
The cancer subtype doesnt play a role in staging, only in treatment decisions.
Survival statistics of women with the major subtypes of breast cancer such as ER-positive, HER2-positive, and triple-negative are grouped together. With treatment, most women with very early stage breast cancers of any subtype can expect a normal life span.
Survival rates are based on how many people are still alive years after they were first diagnosed. Five-year and 10-year survival are commonly reported.
According to the American Cancer Society, 5-year survival rates are:
- stage 0 100 percent
- stage 3 72 percent
- stage 4 22 percent
One thing to note is that these statistics also included women with the more aggressive HER2-positive and triple-negative cancers. And it takes five years to get to a five-year statistical survival rate, so newer therapies are not included in these numbers.
Its likely that a woman with ER-positive breast cancer diagnosed today may have a higher chance of survival.
