Ovarian cyst is a fluid-filled sac or pouch that forms on the ovary. It is normal for a small cyst to develop on the ovaries. But the present of cysts in ovary are often regarded as the cause of ovarian cancer. In fact, ovarian cysts would not trigger ovarian cancer.
Researchers found that ovarian cysts are not associated with an increased risk of ovarian cancer, breast cancer or endometrial cancer. The results could be evidence challenging long-held belief that cyst, which are sacs filled with fluid or other soft tissue would trigger cancer.
“Our data suggest that the cyst was detected through ultrasound screening does not seem to be associated with an increased risk of primary invasive ovarian or hormone-dependent cancers, such as breast cancer or endometrial cancer,” said Dr. Usha Menon from the University College London.
According to the American Cancer Society, about 1 in 71 women get ovarian cancer at some point, with half of the cases occurring after age 60. Data reports from the UK Collaborative Trial of Ovarian Cancer Screening wrote more than 200,000 women aged 50 to 74 years in the UK suffer from ovarian cancer.
According to the report, about half of them are getting ultrasound screening exams regularly. In the first year, screening identified 1,234 women with inclusion cysts, and 22,914 women with normal ovaries. After an average of six years, four women with cysts (or about 5 in 1,000 women) and 32 with normal ovaries (approximately one in 1,000 women) had developed ovarian cancer.
Although that suggests increased risk, statistical tests showed that could easily have been due to chance. According to researchers, the risk for certain types of cancer were not reliably higher in women with cysts, either.
