Understanding Fibroid Bursting

Uterine fibroids are solid, benign muscle tumors that generally don’t “burst” like fluid-filled cysts, but they can undergo acute changes that mimic a rupture. When a fibroid outgrows its blood supply, it may degenerate, tear a blood vessel on its surface, or detach, leading to sudden, intense pelvic pain, internal bleeding, fever, or swelling — symptoms often described as a fibroid burst. These events are rare but can be serious and require immediate medical attention.
