Can you give me info about a ca 27.29 test result?

Depends on value. Ca27-29 is a marker used to follow the course of treatment in patients with advanced breast cancer. However, cancers of the colon, stomach, kidney, lung, ovary, pancreas, uterus, and liver may also raise ca 27-29 levels. Other conditions, including pregnancy, endometriosis, ovarian cysts, benign breast disease, kidney disease, and liver disease can also give elevations.
