What this trial studies

This study collects blood samples and clinical data from women who have survived stage I-III breast cancer to create a biorepository for future research. The primary goal is to gather annotated blood samples, while secondary objectives include collecting data on social determinants of health, environmental exposures, and lifestyle factors. Participants will complete surveys, undergo blood sample collection, and have their medical records reviewed to support ongoing and future studies related to breast cancer survivorship.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older who have been diagnosed with invasive breast cancer stages I-III within the past 7 years and have completed their active treatment.

Not a fit: Patients currently participating in interventional clinical trials or those with stage IV cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this biorepository could enhance understanding of breast cancer outcomes and inform future treatment strategies.

How similar studies have performed: Other studies have successfully utilized biorepositories for cancer research, indicating a promising approach for this initiative.
