Understanding 5 Different Sizes of Ovarian Cysts May Help Your Effective Diagnosis & Treatment

Though ovarian cysts are generally benign and likely disappear even without treatments, they also grow very large causing females a lot of pain. In some cases, they can even promote the formation of new more cysts if not treated or controlled immediately. Other types that are cancerous can as well cause detrimental changes in the body like bloating, pain in the pelvic and abdomen and even increasing more cancer cells that can inhibit the normal operations inside the body. A few studies even show that these ovarian cysts are as well capable of affecting the blood flow and the heart functions. That is why, during the monitoring stages, doctors consider the size of ovarian cysts in the determining further treatments or medical actions.

The size of ovarian cysts varies greatly on the type of the cyst. It may grow or evolve into a larger form but are usually not cancerous. Ovarian cysts generally develop in a size less than of a pea to a size as large as a melon. Occasionally, they may even grow larger and may require surgery especially if they exceed 6 cm in diameter. Ovarian cysts that grow larger than 10 cm cause common symptoms like pelvic and abdominal pain.

Functional Ovarian Cysts

One type of ovarian cysts is the Functional cysts. This type of cysts can disappear in just a few cycles but may also grow, filled with liquid and causing pain on the female. Typically the functional cysts grow at a range of 2 to 8 cm in diameter. There were a few incidents recorded that in this type, the size of ovarian cysts grew even larger but such incidents are very rare and they normally shrink when the ovulation ends. With this type of cyst, surgery is not mostly needed.

Dermoid Ovarian Cysts

Dermoid is the second common type of ovarian cysts. This type occurs mostly in younger women is also referred as the mature cystic teratoma. It can grow from 1 cm to a very large size of 45 cm in diameter, containing a variety of tissues in it like bones, teeth, hair, cells, etc. Despite the likely increase of the size of ovarian cysts in dermoid cases, it is benign.

This type of ovarian cysts also causes severe abdominal pain, especially when the cysts twist around affecting the blood supply.


Endometriomas is another common type of ovarian cysts that is formed during the presence of endometrial tissue in the ovary. The average size of ovarian cysts in endometriomas may range from 0.75 in to 8 in. Often filled with dark-reddish and brownish blood, the endometriomas can cause chronic pain in the pelvic and infertility.

Polycystic Ovary

The Polycystic Ovary causes an enlarged-sized ovary that contains a cluster of small cysts inside. This type of cyst causes the ovary to enlarge ranging from twice as large as the normal ovary to five times larger as the normal ones. Though the general size of the ovarian cysts in the polycystic ovary is small, the number of the cysts may grow to even more than a dozen.


Cystadenomas is a benign cyst that grows from an ovarian tissue, filled with some mucus-type fluid. The size of the ovarian cysts in the cystadenomas case may grow very large, even more than 12 inches in diameter. Due its tendency to grow very large, deformation in the body may as well occur, including painful bouts in the pelvic and abdominal regions.
