The stage of the cancer helps you and your doctor:. Breast cancer stage is usually expressed as a number on a scale of 0 through IV — with stage 0 describing non-invasive cancers that remain within their original location and stage IV describing invasive cancers that have spread outside the breast to other parts of the body. Your pathology report will include information that is used to calculate the stage of the breast cancer — that is, whether it is limited to one area in the breast, or it has spread to healthy tissues inside the breast or to other parts of the body.
As part of a detailed study of prognostic factors in breast cancer, we have analyzed the ten year survival rates of patients with primary invasive carcinomas 2. All the patients were treated initially by at least a modified radical mastectomy. Factors associated with a significantly poorer prognosis were: axillary lymph node metastases suspected on clinical examination; perimenopausal menstrual status at diagnosis; tumor larger than 1.
What is prognosis outlook? How is prognosis estimated? What affects prognosis?
Breast cancer that is only in the breast and has not spread to the lymph nodes has a better prognosis chance of survival than breast cancer that has spread to the lymph nodes. The poorest prognosis is for metastatic breast cancer stage IVwhen the cancer has spread beyond the breast and nearby lymph nodes to other parts of the body. An overall survival rate shows the percentage of people who are alive after a certain period of time after diagnosis of a disease such as breast cancer.
Statistics are given below for the overall survival rates for breast cancer based on certain stages of disease development. I made this page many years ago, when there was nothing like this data available on the internet. Recently this page has been up-dated with the most recent statistics that we can find.
Survival depends on many different factors. It depends on your:. These are general statistics based on large groups of patients.
Breast cancer is defined as Stage 1 when it's evident but confined solely to the area where abnormal cell division began—in other words, it's growing but hasn't spread. Stage 1 cancer is subdivided into Stages 1A and 1B. When detected at this early stage, treatment is usually very effective and the prognosis for is good.
Staging and grading usually happens after your breast tumour has been removed by surgery, as a pathologist will need to test the tissue in a laboratory and examine it under a microscope. The grade of a tumour indicates what the cells look like and gives an idea of how quickly the cancer may grow and spread. Tumours are graded between 1 and 3.
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. Although this stage is considered to be advanced, there are a growing number of effective treatment options. The difference is determined by the size of the tumor and whether cancer has spread to the lymph nodes and surrounding tissue.
