Cancer antigen 15-3 (CA 15-3) protein is produced by normal breast cells. There is an increased production of CA 15-3 in individuals with breast tumour. This test measures CA 15-3 in the blood.

This test is advised to monitor treatment response of breast cancer and watch for or detect recurrence.
Elevated CA 15-3 may also be seen in other non-malignant conditions (cirrhosis, hepatitis, benign breast disease) and malignancies (lung, liver, pancreatic, colon, cervical, uterine, endometrial carcinomas).
What is this test
Cancer antigen 15-3 (CA 15-3) is a protein that is produced by normal breast cells. In many people with cancerous breast tumors, there is an increased production of CA 15-3 and the related cancer antigen 27.29. CA 15-3 does not cause cancer; rather, it is shed by the tumor cells and enters the blood. This test measures CA 15-3 in the blood.
