Early diagnosis of breast cancer is the key to extending survival of breast
-cancer patients. We found that the concentrations of nipple fluid bFGF (ba
sic fibroblast growth factor) was significantly increased in breast-cancer
patients compared with concentrations in controls (1717 ng/L [SD 706] vs 19
ng/L [19]; Student's t test p=0.027). Measurement of bFGF in nipple fluid
could be a useful diagnostic tool for breast cancer, and deserves further s
tudy.
