What are the causes of chronic follicular cysts?

Patient's question:

The causes of chronic follicular cysts are those

Doctor's answer:

Hello
Ovarian cysts usually do not cause symptoms, but you may notice a solid, painless lump in the lower abdomen or experience pain during intercourse. Large cysts can compress the area near the bladder, causing urine retention, although this is rare. When cysts affect hormone production, symptoms such as irregular vaginal bleeding or excessive body hair (see "Hypothalamus-Pituitary-Ovary Dysfunction") may occur. Cysts can also twist, causing severe abdominal pain, nausea, and fever.
Ovarian cysts, more accurately, are classified as ovarian tumors, referring to cystic growths forming within the ovaries. Since they are tumors, they can be benign or malignant, and may be either cystic or solid. Malignant ovarian tumors have a high mortality rate and rank as the leading cause of death among gynecological cancers. Therefore, once a left ovarian cyst is confirmed, it requires attention.
