Staging and grading

Breast Cancer Stages and grading are ways in which healthcare professionals describe the size of your breast cancer stage, whether and how far it has spread, and how fast it may grow (or how ‘aggressive’ it is).Knowing your Breast Cancer Stage and/or grade helps your breast care team plan the best treatment for you. 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.

Grading

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.

Grade 1 – the cancer cells look small and uniform like normal cells, and are usually slow-growing compared to other grades of breast cancer

Grade 2 – the cancer cells are slightly bigger than normal cells, varying in shape and are growing faster than normal cells

Grade 3 – the cancer cells look different to normal cells, and are usually faster-growing than normal cells

Grading for non-invasive breast cancers such as ductal carcinoma in situ (DCIS) is different, and is defined as low, medium or high grade rather than 1, 2, or 3.

Staging

Breast Cancer Stages Staging is used to assess the size of a tumour, whether it has spread and how far it has spread. Understanding the stage of the cancer helps doctors to predict the likely outcome and design a treatment plan for individual patients.The main method used for defining the stage of a cancer is the TNM (tumour, nodes, metastasis) system. The TNM system is often used to categorise cancers into four stages.

Breast Cancer Stage 1 usually means that a cancer is relatively small and contained within the breast.

Breast Cancer Stages 2 usually means the cancer has not started to spread into surrounding tissue but the tumour is larger than in Stage 1. Sometimes Stage 2 means that cancer cells have spread into lymph nodes close to the tumour.

Breast Cancer Stages 3 usually means the cancer is larger. It may have started to spread into surrounding tissues and there are cancer cells in the lymph nodes in the area.

Breast Cancer Stages 4 means the cancer has spread from where it started to another body organ. This is also called secondary or metastatic cancer.
