The breast cancer TNM staging system is the most common way that doctors stage breast cancer. Your scans and tests give some information about the stage of your cancer. But your doctor might not be able to tell you the exact stage until you have surgery. Tumour describes the size of the tumour area of cancer. NX means that the lymph nodes can't be assessed for example, if they were previously removed. Isolated tumour cells ITCs are small clusters of cancer cells less than 0.

Cancer occurs when changes called mutations take place in genes that regulate cell growth. The mutations let the cells divide and multiply in an uncontrolled way. Breast cancer is cancer that develops in breast cells. Typically, the cancer forms in either the lobules or the ducts of the breast. Lobules are the glands that produce milk, and ducts are the pathways that bring the milk from the glands to the nipple.
T followed by a number from 0 to 4 describes the main primary tumor's size and if it has spread to the skin or to the chest wall under the breast. This includes inflammatory breast cancer. N followed by a number from 0 to 3 indicates whether the cancer has spread to lymph nodes near the breast and, if so, how many lymph nodes are involved.
