Ovarian cyst


Hello Doctor: During a visit to the obstetrics and gynecology clinic for an ultrasound, a cyst measuring over 2 centimeters was found on my ovary.
The clinic physician mentioned that most of these cysts will resolve on their own, and suggested another ultrasound after my next menstrual period.
I would like to ask: 1.
Is it normal to have a cyst during menstruation or just before it starts? 2.
Is there a risk of torsion or rupture? 3.
If it resolves on its own, how long does that typically take? 4.
If the next ultrasound shows the cyst is still present but has decreased in size, does that indicate it will completely resolve on its own? I apologize for asking so many questions, and thank you for your help.

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, a 2 cm blister is quite small; just observe and monitor it.
Clinically, there are no symptoms, so there is no need for concern.
Wishing you good health.

Understanding ovarian cysts can be a source of concern for many women, especially when they are discovered during routine gynecological examinations. Here, I will address your questions regarding ovarian cysts, particularly the 2 cm cyst you mentioned, and provide additional insights based on medical knowledge.

1. Is it normal to have a cyst during menstruation?
Yes, it is quite common to have ovarian cysts during your menstrual cycle. In fact, many women develop functional cysts as part of their normal ovulation process. These cysts, known as follicular cysts, form when the follicle (the sac that contains the egg) does not release the egg and instead continues to grow. Most of these functional cysts are harmless and typically resolve on their own within one to three menstrual cycles. If you are currently menstruating or approaching your period, the presence of a cyst is generally considered normal and is often monitored rather than treated immediately.

2. Is there a risk of torsion or rupture?
While most ovarian cysts are benign and do not cause complications, there is a small risk of torsion (twisting of the ovary) or rupture, especially if the cyst is larger than 5 cm. Torsion can lead to severe pain and requires immediate medical attention, as it can compromise blood flow to the ovary. Rupture of a cyst can also cause significant pain and, in some cases, internal bleeding. However, the likelihood of these events occurring with a 2 cm cyst is relatively low. It is essential to monitor any symptoms you may experience, such as sudden, severe abdominal pain, and seek medical attention if they arise.

3. How long does it take for a cyst to resolve on its own?
The time it takes for an ovarian cyst to resolve can vary. Functional cysts often disappear within one to three menstrual cycles. However, the exact duration can depend on factors such as the type of cyst, its size, and your individual hormonal balance. Regular follow-up ultrasounds, as your doctor suggested, are crucial to monitor the cyst's size and ensure it is not causing any complications.

4. If the cyst is smaller at the next ultrasound, does that indicate it will fully resolve?
If the cyst appears smaller on follow-up ultrasound, it is a positive sign that it may be resolving. Many functional cysts will shrink and eventually disappear completely. However, it is essential to continue monitoring the cyst, as some may persist or change in nature. If the cyst does not resolve or if you experience any new symptoms, further evaluation may be necessary, which could include additional imaging or even surgical intervention in rare cases.

In conclusion, while the discovery of an ovarian cyst can be concerning, it is essential to remember that many cysts are benign and self-limiting. Regular monitoring and communication with your healthcare provider are key to managing any concerns. If you experience any unusual symptoms or have further questions, do not hesitate to reach out to your gynecologist for personalized advice and care.
