Stage of breast cancer as a relation to prognosis?

Yes: Breast cancer can be stage 0 non-invasive. Stage1, stage 2, stage 3 and stage 4. Each of the stages has a variety if statistical possible outcomes and results. Also depends on cell type, hormone receptors, dna of the tumor, response to treatments and radiation, underlying health factors, etc. Too complicated to discuss here. The oncologist can be more specific for the patient's specific situation.

Varies: Survival depends on many factors, such as overall health, age, stage of disease and response to treatment. Additional information may be found at www.Cancer.Org.
