Nov. 23, 2004 -- Abdominal cramping and urinary incontinence: These are
early signs of ovarian cancer and
even if isolated or chronic these "abdominal" problems warrant a pelvic exam to
check for ovarian cancer, new research shows.
It's a message to primary care doctors, gastroenterologists, and others who
treat women with these frustratingly vague symptoms that may signal ovarian
cancer. Most women have symptoms for weeks or months before the diagnosis; the
majority of these are related to the entire abdomen and not the pelvis, say
researchers. The probability of ovarian cancer is extremely low. However, a
pelvic exam should be included in the evaluation.
"The message for women is, if you have vague symptoms that last more than
two weeks, if you're over 40, get it checked ... then be persistent; don't quit
until you have a definite diagnosis," researcher Barbara P. Yawn, MD, director
of research at Olmstead Medical Center in Rochester, Minn., tells WebMD. She is
also a professor at the University of Minnesota.
Yawn's study appears in the latest issue of the journal, Mayo Clinic
Yawn and her colleagues carefully reviewed medical records for 107 women
diagnosed with ovarian cancer. "It was done as carefully as you can do a
medical record study," says Yawn. "We may not know everything the doctor was
thinking; if they suspected ovarian cancer but didn't write it down. But we
know what happened, which is the most important aspect. We know if they ordered
follow-up tests or not."
The most common early symptoms:
22% of women had abdominal
pain that persisted for longer than two weeks, not associated with diarrhea
18% had urinary symptoms, such as incontinence, that grew increasingly
worse over two or three weeks' time. "Incontinence usually happens gradually
over several years, not that quickly," says Yawn.
10% of the women had spotting, unusual among women over age 40. "Usually by
then things have settled down quite a bit," she explains.
Many of the women had seen a primary care doctor or gastroenterologist, and
some were referred to a gynecologist -- but not always, Yawn tells WebMD.
"These women were treated for ulcers or other conditions, but they didn't get
any better. Their doctors didn't take the next step; they didn't do a pelvic
exam and ultrasound."
There's an old saying in medical school: "When it's not horses, and you're
still hearing hoof beats, then think zebras. These doctors never got around to
the zebras," she says.
Diagnosing and treating
ovarian cancer in the early stages is key to survival. The cure rate tops
90% if ovarian cancer is caught early. When cancer has spread, about 80% of
women die within five years.
