Ovarian Cancer Tests Flawed, In Need Of New Design, Says Stanford Study

STANFORD, Calif. -- Current diagnostic tests for ovarian cancer are woefully ineffective for early detection of the disease, say researchers at Stanford University School of Medicine. A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter, or about 200-times smaller in mass than those currently used to assess potential new tests. Still, if that hurdle can be overcome, there is good reason to believe that testing could make a big difference: The window of opportunity for treating these clinically undetectable cancers before they become life threatening is surprisingly long: about four years. "We...
