From they NY Times this morning:
"Cancer experts have identified a set of health problems that may be symptoms of ovarian cancer, and they are urging women who have the symptoms for more than a few weeks to see their doctors.
The new advice is the first official recognition that ovarian cancer, long believed to give no warning until it was far advanced, does cause symptoms at earlier stages in many women.
The symptoms to watch out for are bloating, pelvic or abdominal pain, difficulty eating or feeling full quickly and feeling a frequent or urgent need to urinate. A woman who has any of those problems nearly every day for more than two or three weeks is advised to see a gynecologist, especially if the symptoms are new and quite different from her usual state of health."
