Uterine fibroids (leiomyomas or myomas) are benign muscle tissue growths that develop in or around the uterus. These noncancerous tumors can vary significantly in size, from tiny seedlings undetectable to the human eye to large masses that can distort and enlarge the uterus. While many women may have fibroids during their lifetime, not all experience symptoms or require treatment.
Types of Uterine Fibroids
Classification by Location
- Intramural Fibroids
- Most common type
- Develop within the muscular uterine wall
- Can cause uterine enlargement when they expand
- Subserosal Fibroids
- Develop on the outer uterus wall
- Can grow outward into the pelvic cavity
- May cause pressure symptoms
- Submucosal Fibroids
- Develop under the uterine lining
- Grow into the uterine cavity
- Often cause significant bleeding issues
- Pedunculated Fibroids
- Attached to uterus by stalk-like growth
- Can be either subserosal or submucosal
- May cause acute pain due to twisting

Conclusion
Understanding uterine fibroids, their symptoms, and causes is crucial for proper management and treatment.
