Summary Staging [NCI SEER data analysis 2000-2005] [ACS Breast Cancer Facts & Figures]

• 61% or breast cancer cases are diagnosed while the cancer is still confined to the primary site- localized. (Stage I and II)

• 31% are diagnosed after the cancer has spread to regional lymph nodes or directly beyond the primary site - regional. (Stage III)

• 6% are diagnosed after the cancer has already metastasized - metastatic (Stage IV)

• Staging information is unknown for 2% remaining
