Research in Taiwan uncovers new optical breast cancer detection methods
Jul 20, 2011
A finding by researchers in Taiwan published in Analytical Chemistry made recent breast cancer health news, attesting that the common prostate-specific antigen (PSA) blood test for prostate cancer in men has the potential to identify breast cancer in women.
PSA levels in healthy women are extremely low, and tests must be refined and adapted in order to accurately identify problematic bioindicators. However, researchers believe the tests have the potential to provide early, accurate detection while being more comfortable and less invasive than more traditional methods like a mammogram.
The scientists, led by Chien Chou note in their abstract that the experiment's results of t-PSA detection indicate that normalized fluorescent signals in breast cancer patients tested are higher than those in noncancer subjects."
Chou and his team have been researching novel forms of medical optics and fluorescent biosensors to improve screening methods for cancer detection.
The findings could go a long way towards improving detection, encouraging screening and working toward the elimination of improper diagnosis of breast cancer, the leading cause of cancer deaths among women in the United States and a disease that affects more than 200,000 women every year, according to the Centers for Disease Control and Prevention.
