The best thing to do is try and talk to your health care provider as soon as possible. Generally, she or he will assure you that your cyst is most likely benign and often you’ll be given a “best guess” that the cyst is functional (physiologic) and will likely disappear on its own. It’s easy to say don’t panic—but try not to. Remember that the vast majority of cysts between the ages of 13 and 50 are normal structures that you make in the process of ovulation and hormone production. Most ovarian cysts will not cause future problems though they may certainly cause inconvenience. Only a very small number of them will require intervention—surgery .
