Scientists Develop Assay to Help Detect Cancer Causing Medications

The Los Angeles Times reports that researchers have developed a new test to determine the effects of certain medications on sex hormones which may, in turn, influence the development of diseases such as breast cancer. “In a trial screening of 446 drugs in wide circulation, the new assay singled out the popular antidepressant paroxetine as having a weak estrogenic effect that could promote the development and growth of breast tumors in women.” Experts say that “the finding that paroxetine has estrogenic effects ‘has implications for patients with estrogen-sensitive breast cancer who are on other medications.'” The assay “also identified two antifungal medications — miconazole and oxiconazole — as having an anti-estrogenic effect similar to that of medications prescribed to prevent breast cancer and its recurrences in women.”
