What are the Causes of Ovarian Cysts ?
Cysts are fluid-filled sacs that can form in the ovaries. They are very common. They are particularly common during the childbearing years.
There are several different types of ovarian cysts. The most common is a functional cyst. It forms during ovulation. That formation happens when either the egg is not released or the sac — follicle — in which the egg forms does not dissolve after the egg is released.
Other types of cysts include:
Polycystic ovaries. In polycystic ovary syndrome (PCOS), the follicles in which the eggs normally mature fail to open and cysts form.
In women with endometriosis, tissue from the lining of the uterus grows in other areas of the body. This includes the ovaries. It can be very painful and can affect fertility.
These cysts form out of cells on the surface of the ovary. They are often fluid-filled.
Dermoid cysts. This type of cyst contains tissue similar to that in other parts of the body. That includes skin, hair, and teeth.
What are the Causes of Ovarian Tumors ?
Often, ovarian cysts don’t cause any symptoms. You may not realize you have one until you visit your health care provider for a routine pelvic exam. Ovarian cysts can, however, cause problems if they twist, bleed, or rupture.
If you have any of the symptoms below, it’s important to have them checked out. That’s because they can also be symptoms of ovarian tumors. Ovarian cancer often spreads before it is detected.
