There are several prognostic factors associated with breast cancer. Stage is the single most important prognostic factor in breast cancer, as it will take into consideration local involvement, lymph node status and whether metastatic disease is present or not. The higher the stage at the time of diagnosis, the worse the prognosis of breast cancer is. Node negative breast cancer patients have a much better prognosis compared to node positive patients.
Presence of estrogen and progesterone receptors in the cancer cell is another important prognostic factor, and may guide treatment. Hormone receptor positive breast cancer is usually associated with much better prognosis compared to hormone negative breast cancer.
HER2/neu status has also been described as a prognostic factor. Patients whose cancer cells are positive for HER2/neu have more aggressive disease and may be treated with trastuzumab, a monoclonal antibody that targets this protein.
Ashkenazi Jewish women and black women tend to have higher rates of fatalities.
