Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is find out if a protein level in the blood (called PC Cell Derived Growth Factor or glycoprotein 88 \[GP88\]), combined with standard mammography screening, can help detect breast cancer better than mammography screening alone. Earlier research has shown that a certain glycoprotein 88 (GP88) is higher in women with breast cancer. In this study, investigators will measure the level of GP88 in the blood of healthy women who are having mammography screening for breast cancer. The investigator plans to correlate the results of the mammogram with the GP-88 level.
