What causes uterine fibroids to grow

Firstly, uterine fibroids, also known as leiomyomas, are common. They affect about 20-80% of all women. Fibroids are benign monoclonal tumors of the uterine myometrium that affect the smooth muscle cells.

Secondly, these growths are not cancerous (benign), and they may be with or without symptoms. Uterine fibroid symptoms range from irregular bleeding, pelvic/abdominal pain to pregnancy issues.

Thirdly, uterine fibroid starts as multiple, single-cell seedlings seen on the wall of the uterus. They gradually increase in size over many years. The increase is because of the stimulation by estrogens and progestogens.

Fourthly, as the uterine fibroid gets bigger, it outgrows its blood supply. It means that the central areas will not get adequate blood supply leading to benign degeneration followed by calcification.

Lastly, the cause of uterine fibroid is unknown. The position of the fibroid on the wall of the uterus determines the classification.
