Breast cancer stages defined. The stage provides a common way of describing the cancer so doctors can work together to plan the best treatments. Distant stage refers to cancer that has spread to distant organs andor lymph nodes including nodes above the collarbone. Regional stage refers to cancer that has spread to surrounding tissue andor nearby lymph nodes.
This stage describes noninvasive in situ breast cancer. What is breast cancer stage 0. Stage is a prognostic factor and in broad generalization low stage cancers Stages 0-II tend to have better long term outcome than high stage cancers Stages III-IV.
Stage 3 cancer means the breast cancer has extended to beyond the immediate region of the tumor and may have invaded nearby lymph nodes and muscles but has not spread to distant organs. Early stage breast cancer is defined as disease confined to the breast with or without regional lymph node involvement and the absence of distant metastatic disease. Breast cancer stages range from 0 to IV with many subcategories Lower numbers indicate earlier stages of cancer whereas higher numbers reflect late-stage cancers.
Ductal carcinoma in situ DCIS is an example of stage 0 breast cancer. PNX means that the lymph nodes cant be assessed for example if they were previously removed. The tumor is no bigger than 2.
Staging can be clinical or pathological. If breast cancer is found more tests will be done to find out the size and extent of the cancer in the breast and to determine whether the cancer has spread from the breast to other parts of the body. Stage 0 zero which is non-invasive ductal carcinoma in situ DCIS and stages I through IV 1 through 4 which are used for invasive breast cancer.
A higher number such as stage IV means cancer has spread more. Local stage refers to invasive cancer that is confined to the breast. Stage 1 breast cancer means that the cancer is small and only in the breast tissue or it might be found in lymph nodes close to the breast.
Get more details about stage 0 breast cancer types and treatment options. Breast cancer is cancer that begins in lobules ducts or connective tissue of the breast. Breast Cancer Staging System Once breast cancer is diagnosed tests are performed to determine the cancer stage which will influence which type of treatment patients receive.

Breast cancer is staged from 0 to 4. And within a stage an earlier letter means a lower stage. Breast cancer stage ranges from Stage 0 pre-invasive disease to Stage IV metastatic disease.
There may be abnormal cells in the area but they have not spread and cant be confirmed as cancer yet. This is the earliest stage of breast cancer. A breast tumor is larger than 50 millimeters and the cancer has spread to between one and three nearby lymph nodes.
All carcinomas of the breast are covered by this staging system Breast sarcomas phyllodes tumor and breast lymphomas are not staged using this system. This stage is divided into three groups. As a rule the lower the number the less the cancer has spread.
Stage IIIA is based on one of the following. Starting at this level breast cancer is called invasive meaning it has. There are 5 stages of breast cancer.
This is called staging. This is based on the fact that early-stage breast cancer is potentially curable and patients with distant metastatic disease are not. The stages range from Stage 0 a very early cancer to Stage IV the cancer has spread to other organs of the body.
Below is a simplified description using the pathological staging for nodes in breast cancer. PN0 means there are no cancer cells in any nearby nodes or only isolated tumour cells ITCs. Although this stage is considered to be advanced there are a growing number of effective treatment options.
Clinically detected is defined as detected by imaging studies excluding lymphoscintigraphy or by. Stage 2 Stage 2 breast cancer means that the cancer is either in the breast or in the nearby lymph nodes or both. It is an early stage breast cancer.
It then ranges from stage I 1 through IV 4.
