The TNM Staging System The TNM system is the most widely used cancer staging system. This stage is divided into three subcategories. Tumors are measured in millimeters and centimeters ten millimeters equals one centimeter.

Most hospitals and medical centers use the TNM system as their main method for cancer reporting. A higher number such as stage IV means cancer has spread more. You are likely to see your cancer described by this staging system in your pathology report unless you have a cancer for which a different staging system is used.

Any size breast tumor or no tumor is present and cancer has been found in between four and nine lymph nodes. The earliest stage breast cancers are stage 0 carcinoma in situ. The overall stages of cancer range from 0 to 4.
