Medical Definition of CA 15-3

1. Carbohydrate antigen elevated in patients with tumours of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer. (12 Dec 1998)
