It is most common in women with normal ovaries and does not require additional 72,000 women to undergo additional research or surgical removal, depending on the new study and 119,00 hip ultrasound examinations for decades.
The study found that collaboration between UC San Francisco and Kaiser Permanente Washington, common cysts, is commonly found to be widespread in women of both early and subsequent patients and is not associated with high risk of cancer. As a result, researchers were discovered, if they were not symptomatic, simple cysts were disregarded safely.
On the contrary, complicated cysts or solid mass are much more common, but are associated with the risk of developing malignant neoplasms. These masses need to be stored or surgically removed.
An article published on November 12, 2018 Internal diseases of JAMA, typical cysts usually monitored and sometimes offer a way to treat the cure.
According to Rebecca Smith-Bendman, a professor of radiology and biomedicine research, "there is a lot of unnecessary medical controls for simple cysts." Professor at the Department of Epidemiology and Biostatistics, Obstetrics, Gynecology and Reproductive Medicine Philip R. He is a member of Lee's Health Policy Research Institute.
"Simple cysts are at a good level, but they are concerned that they threaten the oncological precursor, which often leads to tracking and gynecologists and oncologists," he said. "Our study is a simple assimption of any size that simple cysts should be considered normal detection of women of all ages."
Cervical Cancer – The fifth cause of cancer deaths among women in the United States is 22,000 new cases per year and 14,000 deaths.
The use of transvaginal pelvic ultrasound in the last two decades has resulted in more identification of the kidney mass. Although most of these masses are diet, researchers and professional guidelines suggest that regular cysts are constantly monitored due to the poor prognosis of malignant neoplasms, as well as malignant cancer-related malignancies.
This is the first study to quantify the risk of stomach cancer in a non-selective population, based on ultrasound characteristics of the perimeter mass, including simple cysts. The authors have tried to identify the possibilities that prove that kidney massage is good and does not require supervision.
During the period from January 1997 to December 2008, 72,093 women with hip ultrasound were recorded by Kaiser Permanente Washington in the study. About 75 percent of them are less than 50 years old.
During the study period, 118 778 hip ultrasonic examinations were performed. Of 54,452 women under the age of 50, according to researchers, about 24 percent (12,957 women) diagnosed with simple cysts and did not develop cancer later. Approximately 13 percent (2 349 women) of 17691 women aged 50 and older diagnosed with simple cysts, one of whom was diagnosed with cancer.
In the statistical analysis, the risk of developing cancer was zero for women with normal cysts, regardless of the size of the tumor. During the study, 210 cases of cancer have been identified, all of which have been reported in women with complicated mystical mass.
Ultrasound presupposes the likelihood of malignant neoplasms, and for women with complicated mystical or solid napkin mass, this has significantly increased. They estimated that 6.5 percent of men and women after such mass lesions had been diagnosed with cancer for three years. On the contrary, women with congenital cancer are not associated with malignant neoplasms than normal females. The authors admit that women with a history of malignant neoplasm have restrictions not included in the study.
"It's one of the basics of tracking ordinary cysts," said Smith Bindman, a member of the UCSF Helen Diller Family Comprehensive Cancer Center. "These data are not supported by us. Simple, even cysts, which are considered to be very large, are not associated with malignant tumors.
"I understand why women and doctors do not want to properly diagnose ovarian cancer," he said. "The predator is a malignant tumor. But malignant ovarian cancer does not develop in simple cysts and the appearance of simple cysts does not improve early detection of gastric cancer. "
