Uterine leiomyomas, generally called fibroids, are properly-circumscribed, non-cancerous tumors arising from your myometrium (smooth muscle layer) of your uterus. In addition to smooth muscle, leiomyomas are also composed of extracellular matrix (i.e., collagen, proteoglycan, fibronectin). Other names for these tumors consist of fibromyomas, fibromas, myofibromas, and myomas.
Leiomyomas are the most widespread reliable pelvic tumor in females, causing signs in roughly 25% of reproductive age females. Nevertheless, with careful pathologic inspection of the uterus, the total prevalence of leiomyomas increases to through 70%, because leiomyomas might be present but not symptomatic in many ladies. The normal affected uterus has 6 to 7 fibroids.
