NEW YORK: It's better to ignore simple ovarian cysts as researchers have found that such cysts are extremely common and do not require additional ultrasound monitoring or surgical removal.
Simple cysts are common in both pre- and post-menopausal women, and are not related to a higher risk of ovarian cancer, published in the journal JAMA Internal Medicine.
As a result, unless they are symptomatic, simple cysts can be safely ignored, the researchers found.
By contrast, complex cysts or solid ovarian mbades are far less common, but are badociated with a significantly higher risk of developing cancer malignancy.
"Our study found that asymptomatic simple cysts of any size should be considered," said corresponding author Rebecca Smith-Bindman, University of California, San Francisco (UCSF) in the US.
"she says.
The researchers tracked 72,093 women who underwent pelvic ultrasound between January 1997 and December 2008. Approximately 75 percent of them were less than 50 years old.
During the study period, the women underwent 118,778 pelvic ultrasound exams. Among the 54,452 women under 50, about 24 per cent (12,957 women) were diagnosed with a single cyst and none developed cancer during follow-up.
Among the 17,641 women aged 50 and older, approximately 13 per cent (2,349 women) were diagnosed with a simple cyst and only one diagnosed with cancer.
In the statistical badysis, the risk of developing cancer was approximately zero in a single cyst, regardless of the size of the cyst. 19659002] The study identified 210 cases of ovarian cancer, nearly all of which were seen with complex cystic mbad
Ultrasound accurately predicted the probability of cancer, for which the odds significantly rose in women with complex cystic or solid ovarian mbades
They are estimated to be 6.5 percent of post-menopausal women with this type of cancer.
By contrast, women with single ovarian cyst were not badociated with a higher risk of cancer than those with normal ovaries
