An ovarian cyst is a common condition that menstruating women suffer from. It is a fluid-filled sac within the ovary that usually occurs due to hormonal imbalance, particularly estrogen excess. When these cysts are small, they are usually painless. As they grow large, they start to cause health complications like breast tenderness, pain during intercourse, pelvic pain before or during the menstrual cycle, uterine bleeding, irregular periods, spotting, and bloating.
If not treated promptly, these symptoms build on to progress to a more complex condition, known as PCOS (polycystic ovary syndrome).
