Can ovarian cancer be detected during pregnancy?

Yes: Some patients have surgery to explore and/or attempt to reduce or cure symptomatic disease. Mris aren't always terribly useful for ovarian cancers but are sometimes helpful when surgery isn't a great option. The ca125 tumor marker can often be informative as well but isn't very specific to ovarian cancer and may be falsely elevated. Conservative approaches are best until the pregnancy is finished.

Yes: It certainly could be diagnosed particularly given all the ultrasounds that are done.
