What this trial studies

This observational study investigates a lab-developed biological test that analyzes tears to aid in breast cancer screening for women with dense breast tissue. The test, designed and validated by Namida Lab, Inc., aims to serve as a supplemental tool alongside existing screening methods. Participants will use a Schirmer Strip to collect tear samples, which will be analyzed to determine the presence of breast cancer. The study focuses on women aged 18 and older who have been categorized with heterogeneously dense or extremely dense breast tissue.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 and older with heterogeneously dense or extremely dense breast tissue.

Not a fit: Patients with active eye infections, those with fatty breast tissue, or currently diagnosed with breast cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this test could provide a non-invasive and effective screening option for early detection of breast cancer in women with dense breast tissue.

How similar studies have performed: While this approach is innovative, it is not widely tested in similar studies, making it a novel exploration in breast cancer screening.
