Ovarian cyst surgery often unnecessaryApril 9, 2019
Wouter Froyman et al shows evidence promoting a watchful waiting approach towards non-cancerous ovarian cyst. The researchers performed a two-year study involving 1919 women from 10 different countries, including the UK, Belgium, Sweden and Italy, who were diagnosed with non-cancerous ovarian cysts. The average age of the women in the study was 48, and the average size of the cyst was 4cm. Out of the 1919 women in the trial, 20 percent had cysts that disappeared of their own accord, and 16 percent underwent surgery. Overall, in 80 percent of cases either the cyst resolved or did not need intervention. Only 12 women were subsequently diagnosed with ovarian cancer, making the risk of cancer 0.4 percent. The rate of other complications, such as ovarian twisting or cyst rupture was 0.4 percent and 0.2 percent respectively. The researchers suggest that the risk of malignancy and acute complications is low if adnexal masses with benign ultrasound morphology are managed conservatively, invasive surgical procedures can be avoided.
