What this trial studies

This study involves the collection of tissue samples during standard surgical procedures for patients diagnosed with breast cancer. In addition to tissue, a one-time blood draw will be performed, and there may be an optional rectal swab for biome analysis. The follow-up will consist of chart reviews to monitor for recurrence, metastases, or death. The goal is to gather biospecimens that can be used for future research on breast cancer.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are undergoing surgical procedures for invasive breast cancer or carcinoma in situ.

Not a fit: Patients under 18 years old or those unable to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of breast cancer biology and improve future treatment strategies.

How similar studies have performed: Other studies involving biospecimen collection in cancer research have shown success in advancing understanding and treatment options, making this approach well-established.
