A left ovarian cyst of 30 mm is not serious if it is caused by physiological phenomena. It is more serious if the lesion is caused by infection or surgery.
Normally, during each menstrual cycle, the follicle will mature and release the egg. If the follicle does not rupture and release the egg, it may lead to follicular fluid retention and form a cyst. This is a physiological phenomenon and can return to normal size on its own, so it is not serious.
If the ovarian cyst appears due to pathological changes caused by smoking, infection, surgery, etc., it may be followed by infection, cyst tip torsion, etc., which will adversely affect the patient’s life, work, etc., and even threaten her life. So it is more serious.
It is recommended that patients with left ovarian cysts of 30mm, after excluding physiological phenomena, go to the hospital in time to improve the relevant examination, and follow the doctor’s instructions for targeted treatment to avoid delaying the condition.
