Types of the cysts

In most cases the cysts are formed on the outer wall of the ovaries or inside them. Relatively rarely, cysts are diagnosed on the labia. They can also appear on the so-called Bartoline glands. Such cysts occur as a result of inflammation of the gland. In addition, ovarian cysts during pregnancy can occur in the muscles and cervix, vaginal wall, as well as in the fallopian tubes.

There are those cysts that cause extremely painful sensations, unpleasant symptoms and require treatment. For example, chocolate cyst is a symptom of endometriosis. This abnormal growth of endometrial tissue or mucosa. Endometriosis reduces the likelihood of conception and complicates the course of pregnancy, causing problems such as menstrual irregularities, painful menstruation and intermenstrual bleeding.

Another common type of cyst is small cysts that appear in polycystic ovary syndrome (PCOS). This disorder also causes difficulties in pregnancy and menstrual disorders, as well as excessive weight gain and excessive hair growth (hirsutism).

More often women have ovarian cyst. Only 10-15% of the cysts are malignant. Therefore, immediate surgery is not required, instead, it is recommended to see a doctor and sometimes hormonal treatment.
