As Herbert Eder, when dealing with an ovarian cyst, I begin by determining its exact type. A functional cyst, an endometrioma, and a dermoid cyst each follow different courses. These differences also serve as the basis for conclusions regarding frequency therapy and potential treatment outcomes.
An ovarian cyst is a cavity on or inside the ovary that may contain fluid and, depending on the type, other substances as well. Many cysts go unnoticed and resolve on their own. However, the term „cyst“ alone is not sufficient to determine treatment: symptoms, the course of the condition, and specific test results determine whether a “wait-and-see” approach is appropriate or if further steps are necessary. [1]
If you learn that you have a cyst, the first step is to get a clear explanation: What type is suspected, what is the basis for this assessment, and what is still unclear? Also ask whether the recommendation is based on symptoms, an abnormal ultrasound finding, or is being made as a precautionary measure to monitor the cyst’s progression. These different reasons should not be conflated during the discussion. A clear diagnostic report is often more helpful for this purpose than a standalone measurement of the cyst’s size.
Not every ovarian cyst is a functional cyst
Functional cysts develop in connection with the menstrual cycle. A follicle may persist if ovulation does not occur; after ovulation, fluid or blood may accumulate in the corpus luteum. Such changes often resolve within a few months. They must be distinguished from other conditions, such as an endometrioma associated with endometriosis, a dermoid cyst, or a cystadenoma. These conditions have different causes and require an appropriate evaluation. [2]
An endometrioma typically contains old blood and may be associated with pain or difficulty getting pregnant. Dermoid cysts can contain various types of tissue. The term „complex“ initially describes a finding that is not exclusively a simple fluid-filled lesion; it does not yet provide a definitive conclusion regarding whether the lesion is benign or malignant. The next steps depend on the specific characteristics of the lesion. [2]
What Symptoms Should Be Investigated
Many cysts do not cause any symptoms. Possible symptoms include lower abdominal pain, a feeling of pressure, pain during sexual intercourse, a frequent urge to urinate, or changes in menstrual bleeding. A persistent feeling of fullness may also be a reason to seek medical evaluation. However, such symptoms can have various possible causes. Therefore, the discovery of a cyst does not automatically explain them completely, and an examination should not be limited solely to the findings already known. [4]
Before your appointment, you can note down when your symptoms began, whether they change with your menstrual cycle, and which daily activities are affected. Bring any previous medical records and a list of your medications with you. Also, let us know if pregnancy is a possibility, if you’re trying to conceive, or if your periods have already stopped permanently. This will ensure that the consultation addresses the issues most important to you right from the start.
What Is Assessed During an Ultrasound Exam
A gynecological ultrasound can be performed through the abdominal wall, through the vagina, or using a combination of both methods. The procedure should be explained to you beforehand and discussed with you. It shows the location, size, and internal characteristics of a lesion. Despite its excellent imaging capabilities, ultrasound does have its limitations: Sometimes a repeat scan or another type of examination is necessary to reliably answer a specific question. [12]
The assessment takes into account the wall, chambers, and any solid components. A simple fluid-filled cyst with smooth borders differs from a lesion with multiple chambers, thickened septa, or tissue projections. These features are more informative for risk assessment than the nonspecific term „cyst.“. [6]
O-RADS standardizes descriptions and risk classifications. However, a category is not a tissue diagnosis. Recommendations for follow-up care must be tailored to the individual’s situation; in particular, they are not instructions to wait for a previously scheduled examination appointment if sudden, severe pain occurs. [3]
Ask for an explanation of the terms in the report that are relevant to the next step. What do „simple,“ „hemorrhagic,“ or „unclear“ mean? Is the next image intended merely to compare sizes or to better assess a specific structure? If an additional test is suggested, ask for an explanation of which unanswered question it is intended to address. This helps prevent the misconception that every additional test already confirms a serious suspicion.
What a Blood Test Can Tell You
The CA-125 tumor marker can be part of the overall assessment, especially after menopause. However, it does not alone determine whether cancer is present: A normal level does not definitively rule out a malignant condition. The key is to consider it in conjunction with symptoms, ultrasound results, and other findings. [5]
Benign conditions can also cause CA-125 levels to rise, such as endometriosis, inflammation, or menstruation. An elevated level must therefore be evaluated in context and does not, on its own, constitute a cancer diagnosis. [4]
When Observation Is a Well-Reasoned Decision
If the findings appear normal and there are no significant symptoms, it may be appropriate to wait and see for the time being. Whether and when a follow-up ultrasound examination is necessary will be determined based on the suspected type of cyst and the course of the condition. The follow-up examination is intended, for example, to determine whether a functional cyst is resolving. It is therefore a targeted assessment of a hypothesis and not merely a delay in treatment. [9]
The international IOTA5 study followed women whose ultrasound findings were assessed as benign and who were initially managed conservatively. In the evaluation of new findings, severe acute complications and invasive malignant tumors detected later were rare over a two-year period. The results support a watch-and-wait approach for carefully selected findings. However, they should not be generalized to every unexplained mass: selection based on the ultrasound image and the agreed-upon management plan were key prerequisites. [7]
A large study involving more than 72,000 women also found no increased risk of ovarian cancer later in life associated with simple cysts. This is a reassuring finding regarding a specific imaging result. It does not mean that size, symptoms, or new features are insignificant. Above all, once a cyst has been assessed as benign, it should be reevaluated if there is a significant change. [6]
What to Expect After Menopause
After menopause, ovarian findings are evaluated with particular care. Nevertheless, not every simple cyst requires surgery or ongoing monitoring. The RCOG guideline, updated in December 2025, allows asymptomatic women with simple, unilateral, single-chambered cysts up to and including three centimeters in size to forgo routine follow-up. Different considerations apply to larger, abnormal, or symptomatic findings. Therefore, size alone is not sufficient to apply this recommendation. [5]
If you’re advised to undergo monitoring after menopause, ask for the specific reason. What benign findings were observed? Is there a follow-up appointment, and what result would change the plan? If no further testing is required, it should also be clear under what new symptoms you should contact your doctor. A clear explanation can reduce unnecessary worry without downplaying any existing concerns.
Why the pill doesn't eliminate existing cysts any faster
The combined birth control pill prevents ovulation. This led to the assumption that it might also cause existing functional cysts to disappear more quickly. A Cochrane review of eight randomized trials involving a total of 686 women did not confirm this. The cysts did not regress any faster while on the pill than without this treatment. A prescription may be based on other reasons, such as contraception or menstrual symptoms; this should be explained separately from the goal of cyst treatment. [8]
If hormone therapy is recommended, be sure to ask explicitly what the goal is. Is the treatment intended to address an existing change, influence future cycle regulation, or improve another issue? How is it determined whether the chosen goal has been achieved? Do not change a treatment you are already using based solely on an online article; instead, discuss the specific reason for the change and the available alternatives.
When Surgery Is Considered
Persistent symptoms, growth, or a suspicious finding may indicate the need for surgery. If the changes are likely benign, laparoscopy is often an option. A cystectomy removes the cyst, while an oophorectomy removes the ovary. These are different procedures. If cancer is suspected, a different approach—including open surgery—may be necessary to ensure that the lesion is removed as intact as possible and properly examined. [9]
Simply aspirating fluid is no substitute for a reliable evaluation of an unclear finding. After menopause, such aspiration is not recommended as a standard treatment for cysts; however, specific palliative situations should be distinguished from this. [5]
Before a scheduled procedure, discuss exactly what is to be removed and under what circumstances the surgery might need to be expanded. Also ask how unexpected findings would be handled. Your thoughts on fertility, hormone preservation, and the extent of the procedure should be part of this discussion. A blanket age limit is no substitute for weighing imaging findings, symptoms, risks, and personal goals.
Ovarian Function, Pregnancy, and Postpartum Care
Before menopause, as much healthy ovarian tissue as possible is preserved. If both ovaries must be removed, surgical menopause begins immediately. The consequences of such a decision must be discussed in detail beforehand. A cyst alone, however, does not necessarily mean that such a removal is imminent; the extent of the procedure depends on the individual findings. [1]
Simple cysts can also disappear during pregnancy. Larger, complex, or painful cysts require care tailored to the needs of pregnancy. [11]
After surgery, the pathology results and follow-up care should be discussed. [10]
After a laparoscopy, you may experience temporary abdominal pain; shoulder pain caused by residual surgical gas may also occur. Discuss pain management with the medical team. Arrange for transportation home and support for the first night. The anesthesia may initially impair your judgment; therefore, you should make practical arrangements for your recovery period before the procedure. [13]
Increasing abdominal pain, fever, persistent vomiting, or unusual wounds require prompt medical evaluation following a laparoscopy. Unusual bleeding or discharge should also be investigated. In cases of severe shortness of breath or chest pain, immediate emergency care is required. Such symptoms are not part of the recovery process that you should simply wait out without seeking medical advice. [14]
Sudden, severe lower abdominal pain—especially when accompanied by vomiting, dizziness, or rapid deterioration—may indicate a twisted appendix, a rupture, or bleeding. Such symptoms require prompt emergency evaluation. A known cyst that has been harmless so far is no reason to wait and see if acute warning signs appear. [2]
Frequency therapy requires a clearly defined diagnosis of a cyst
Many functional cysts resolve on their own without specific treatment. Therefore, a subsequent normal imaging result alone does not prove the effectiveness of a frequency therapy used concurrently. Conversely, the absence of pain should not be taken as definitive proof that an unclear imaging finding has resolved without further investigation. [1]
When evaluating an offer, I recommend asking a specific question: What type of cyst was examined, using which control group, and what were the results? A general device reading regarding „female balance“ is no substitute for a gynecological assessment. Follow-up intervals and the response to acute symptoms remain dependent on the specific findings.
