Though there are various types of ovarian cysts, the most common are the follicle cysts. These cysts are formed when the follicle/sac that holds your egg fails to break open and does not release the egg.

ovarian cyst sizing more than 5 cm:

So the answer to your question, “what is considered a large ovarian cyst?” is here..

Yes, if your ovarian cyst starts growing more than 5 cm in diameter you can clearly consider it a big cyst and you need to take it seriously.

6 cm or above ovarian cyst:

Although many ovarian cysts don’t grow this large, there are cases when cysts get very bigger like more than 6 cm in diameter. This is undoubtedly a big cyst and you are at risk of ovarian torsion.

Ovarian torsion is the condition when the heavy cyst makes the ovary to get twisted. This is a condition which cuts off the blood supply to the ovary, causing an intense pain. This commonly happens once the cyst grew more than 8 cm and doctor attention is immediately required.

Remember, Different doctors consider different sizes to be bigger:

Just found a true story across forums and wanted to share with you.

It can depend on the type of cyst and doctor as to whether or not 6.4 cm is considered big. I had a hemorrhagic cyst about that size and the only person who panicked was my gastroenterologist when she saw it on the CT scan. For her, it was big and ugly. For my GYN, no biggy. For the radiologist who redid the ultrasound, no biggy and it was already absorbing on its own. Source(hystersisters)

I am not against doctors, but this is the reality. In fact, you need to understand that different doctors may consider the different size of the ovarian cyst to be a big one. So all you must follow is your reports.

When should you consider an Ovarian cyst removal surgery?

is a 3 cm ovarian cyst big?


Although size is a crucial factor in deciding the treatment for an ovarian cyst, there are a number of factors you must consider before you decide to undergo a surgery for ovarian cysts.

The various factors include –

a) The rate of growth of your cyst:

More than the size of the cyst, this is a more important factor you must look out for. There may be a small ovarian cyst, but growing at a rapid rate. On the other hand, there may be a very big cyst,  which is naturally reducing in its size.

So, if you are deciding for the treatment of your cyst, you need to properly look out for your ultrasound reports to observe the rate of growth of your ovarian cyst.

b) The Appearance and contents of your ovarian cyst:

As I have already told, there are different types of ovarian cysts. Out of them, some of them may be made of fluids, while some of them may be solid in nature. Thus you need to definitely consider the appearance and the things your ovarian cyst is holding.

c) The Seriousness of your symptoms:

The best indicator of any disease is the symptoms in your body. Although you may not feel any symptoms when your cyst is smaller, as it grows in size, you can clearly observe the symptoms. Thus, when you start to feel the severe symptoms of sudden pain, fever, dizziness, difficulty breathing etc you can immediately rush to a doctor.
