The widely known PSA blood test for prostate cancer in men may get a second life as a much-needed new test for breast cancer, the most common form of cancer in women worldwide, scientists are reporting in a new study in the ACS journal Analytical Chemistry.
Chien Chou and colleagues say that the prostate-specific antigen (PSA) measured in the test also is a potential biomarker of breast cancer in women. However, levels of PSA in healthy women are usually so small that only ultrasensitive tests can measure them.
To improve PSA detection in women, the researchers built ...
