Uterine fibroids, also known as leiomyomas or myomas, are benign monoclonal neoplasms originating from the smooth muscle tissue of the uterus, known as the myometrium. These tumors are composed of a mix of smooth muscle cells and fibroblasts, embedded in a substantial extracellular matrix, which contributes to their growth and development. Fibroids are highly heterogeneous in terms of their size, location, and clinical symptoms, and they can cause significant morbidity, including excessive menstrual bleeding, anemia, and infertility. The prevalence of fibroids is notably high, affecting up to 80% of women by the age of 50, with a higher incidence and severity observed in black women compared to white women. Despite being benign, fibroids can mimic malignant tumors and are a leading cause of hysterectomy. The exact etiology of fibroids remains unclear, but they are known to be hormone-dependent, primarily influenced by estrogen and progesterone, and often shrink after menopause.
Types of Uterine Fibroids
Uterine fibroids, though benign, come in various types based on their location within the uterus. Each type can present different symptoms and affect women’s health in unique ways. Understanding these distinctions is crucial for diagnosis and treatment options. Below is a list of the most common types of uterine fibroids and their characteristics:
- Hypo-intense fibroids
- Iso-intense fibroids
- Heterogeneous hyper-intense fibroids
- Homogeneous hyper-intense fibroids
- Submucous fibroids
- Subserous fibroids
- Intramural fibroids
Common Causes of Uterine fibroids
Understanding these common causes can help in identifying potential risks and managing the condition effectively. Below are some of the most recognized factors associated with the formation of uterine fibroids:
- Hormonal factors (especially high levels of estrogen and progesterone)
- Genetic factors
- Growth hormones
- Micronutrient deficiencies (e.g. vitamin D deficiency)
