Prenatal blood test sometimes hints at cancer in moms-to-be: study

NEW YORK, Dec. 6 (Xinhua) -- Many moms-to-be opt for blood tests during pregnancy to check for fetal disorders such as Down syndrome, and in rare instances, these tests can reveal something unexpected -- hints of a hidden cancer in the woman, The Associated Press cited a study earlier this week.

In the study of 107 pregnant women whose test results were unusual, 52 were ultimately diagnosed with cancer. Most of them were treated and are now in remission, although seven with advanced cancers died.
