Breast cancer is a type of cancer that forms in the cells of the breast. In the 1990s, this was fourth on the list of most commonly diagnosed cancers in India, and now it is topping the list. In 2020, there were about 2.3 million breast cancer cases, representing about 11.5% of the total cancer cases.
The breast cancer stages are a critical factor in determining the best treatment options and the overall prognosis for the patient. Based on clinical and pathological tests, the cancer is categorised into separate stages.
However, multiple breast cancer stages can be easily described with the help of a tool called the TNM staging breast cancer system. Continue reading this blog to understand the stages of breast cancer and the TNM staging system.
Breast cancer is a serious and potentially life-threatening disease affecting millions of people worldwide. Breast cancer is staged to determine the extent and severity of the disease.
The stage of breast cancer is based on the size and location of the tumour, whether the cancer has spread to lymph nodes, and whether it has spread to other parts of the body.
The most commonly used staging system for breast cancer is the American Joint Committee on Cancer (AJCC) TNM staging breast cancer system, which stands for Tumor, Node, and Metastasis.
The TNM staging system helps to assign a stage to the breast cancer, ranging from stage 0 to stage IV and determine the best treatment options and the prognosis for the patient.
In addition to the TNM staging breast cancer system, the results obtained from the biopsy tests and scans are combined to determine a person's cancer stage. This staging that is done can be either clinical or pathological. The clinical staging is done based on the test results obtained in the pre-testing phase. It includes

There are five stages of breast cancer, depending upon the severity and advancement of the illness. They have been enumerated as 0, 1, 2, 3 and 4, where stage 0 is the least lethal form, and stage 4 is the fatal form of breast cancer. The doctors use this system to suggest the necessary treatment.
It signifies the beginning of the disease. It is also called ‘Ductal Carcinoma In Situ’ (DCIS), the non-invasive form or pre-cancer stage.
Stage 1 is the second stage. In this breast cancer stage, the cancer is still very early, but it is invasive at this point. The tumour cells spread to the surrounding tissues in the breast but are restricted to a small area. This stage can further be divided into two parts — stage 1A and stage 1B.
In Stage 2, the cancer cells grow larger, and the lymph nodes may or may not contain cancer cells. This stage can is further divided into two sub-stages:
In stage 3 breast cancer, the tumour has increased and spread further into the breast region.
Here is a general chart outlining the different stages of breast cancer and their characteristics:
Stage of Breast Cancer | Tumour size and location | Condition of lymph nodes |
Stage 0 Breast Cancer | Extremely small lump in the breast | No spread of breast cancer |
Stage 1 Breast Cancer | Tumour size <= 20 mm | Breast cancer does not spread to the lymph nodes |
Stage 2 Breast Cancer | 20 mm<=Tumour size <= 50 mm | May or may not have spread in 1 or 2 lymph nodes |
Stage 3 Breast Cancer | Tumour size >= 50 mm | Spread in 4 to 9 lymph nodes, especially near the collarbone and skin |
Stage 4 Breast Cancer | Tumour size can be of any size and much greater than 50 mm | Spread in all nearby lymph nodes |
The breast cancer stages at the time of diagnosis play a crucial role in determining the most appropriate treatment options. The line of treatment for different breast cancer stages does not have too many differences.
