- Overall Survival?
- Time to recurrence?
- Location of first clinical evidence of metastasis?
- Growth of tumor in nests and sheets versus large mass detectable by mammogram and/or ultrasound?
- Chemosensitivity or chemoresistance by specific drug or type of drug class?
- Age, ethnicity, culture?
- Pre/peri/post menopausal status?
- Number of pregnancies and diagnosis relative to last or current pregnancy?
