ANN ARBOR, Mich. -- A new University of Michigan Medical School study sheds light on cell defects that lead to one common type of ovarian cancer and puts forth a promising new mouse model that already is being used for preclinical drug testing.The study, published in the April issue of Cancer Cell, focuses on ovarian endometrioid adenocarcinoma, the second most common form of a baffling, deadly disease for which early detection methods and effective treatments have been elusive so far. The American Cancer Society estimates there will be 22,430 new cases of ovarian cancer and 15,280 deaths from the disease in the United States this year. >>> Discuss This Story
