Four types of uterine fibroids

Uterine fibroids are a common type of benign tumor in women. Uterine fibroids are classified according to the different locations of the fibroids. The following gynecological experts introduce the classification of uterine fibroids:

1. Intramural fibroids: Uterine fibroids are more common at the beginning. The fibroids are located within the uterine muscle wall and are surrounded by the myometrium. It is the most common uterine fibroid in women, accounting for about 60-70% of all uterine fibroids.

2. Submucosal fibroids: Submucosal fibroids account for about 10%. They are formed by intramural fibroids growing in the uterine cavity, protruding in the uterine cavity, and directly contacting the mucosal layer. This tumor can gradually increase the deformation of the uterine cavity and is often connected to the uterus. For example, a long pedicle can block the cervix or detach from the vagina.

3. Subserosal fibroids: Subserosal fibroids are a common type, accounting for about 20%. Intramural fibroids develop into the serosa, protrude from the surface of the uterus, and directly contact the serosa. If it grows between the leaves of the broad ligament, it is an intra-ligament fibroid.

4. Cervical fibroids: It is a rare type of uterine fibroids. The fibroids grow in the cervix. Because of the low growth position, they can be embedded in the pelvic cavity, causing compression symptoms, making surgical removal difficult and easily damaging the ureter and bladder.

Gynecological experts warn: If uterine fibroids are not treated in time, they will often cause infertility as the size of the fibroids increases. The reason for infertility caused by uterine fibroids is usually because the cervix or the inner opening of the fallopian tube is blocked, affecting the passage of sperm, or the fibroids occupy the site of implantation of the fertilized egg, making it impossible to give birth. Even if pregnancy occurs, it often causes miscarriage due to the impact on embryo development. As for the late pregnancy, premature birth, obstructed delivery or postpartum hemorrhage may be caused by abnormal uterine contraction.
