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.
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.
What grade is the breast cancer? What size is the breast cancer? Cancer cells are given a grade according to how different they are to normal breast cells and how quickly they are growing.
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.
Right now, there is not a simple test that can determine all of this and, moreover, what these factors—in combination—mean for a patient. TNM is the most widely used staging system for breast cancer. Each letter of the acronym stands for a defining element of one's disease.
The past two decades have seen a dramatic increase in the number of women diagnosed with T1a and T1b breast cancer. This rise in early-stage breast cancer is largely attributed to the increase in screening mammography that can detect cancer in its early stages, in some cases when the tumors are under 1cm and before the tumor has spread to the lymph nodes. In T1a breast cancer, the tumor size is less than or equal to 5 millimeters mm ; in T1b, the tumor size is greater than 5 mm, but less than or equal to 10 mm. And are there others—with different combinations of tumor size and subtype—for whom chemotherapy would significantly increase survival?
When it comes to tumour size, axillary lymph node status, and outcome after invasive ductal breast carcinoma, several facts have been established. The first is that the larger the tumour in diameter, the greater the number of axillary lymph nodes that will be found to be affected by metastatic cancer 1. The second is that that the larger the tumour size, the worse the outcome 12.
