The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer. The 5-year relative survival rate drops to 22% for women with stage IV breast cancer. [3]

The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1] It is calculated to select patients for adjuvant treatment.
As knowledge of cancer cell biology develops these classifications are updated. The purpose of classification is to select the best treatment. The effectiveness of a specific treatment is demonstrated for a specific breast cancer (usually by randomized, controlled trials). That treatment may not be effective in a different breast cancer.
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
The rate of death due to breast carcinoma was also influenced by grade, with 90% occurring in 40, 13, and 8 years among patients with grades 1, 2, and 3 tumors, respectively.” [12] [30] Immunohistochemistry of breast cancer (Infiltrating ductal carcinoma of the breast) assayed with anti HER-2 (ErbB2) antibody.
Comedocarcinoma is a kind of breast cancer that demonstrates comedonecrosis, which is the central necrosis [1] of cancer cells within involved ducts. Comedocarcinomas are usually non-infiltrating and intraductal tumors, characterized as a comedo-type, high-grade ductal carcinoma in situ (DCIS).
