Uterine leiomyoma pictures

We know what uterine leiomyoma is, but we don't know what causes it. What causes uterine leiomyoma? This is something we need to discuss. Let's take a look at what causes uterine leiomyoma. Until now, it is still unclear what the cause of uterine fibroids is. Because there are many factors that increase uterine fibroids, its cause is still not very clear.

1. There are many reasons for the onset of uterine fibroids, such as the use of estrogen by the pregnant mother during pregnancy, the first menstruation at a young age, the absence of pregnancy, late marriage and childbearing, and obesity. There are also some studies showing that uterine fibroids are dependent on growth hormone for their development. What's going on? Because uterine fibroids grow more frequently during childbearing years, but are not discovered during puberty, and often occur in older age and during menopause. The offensive flow may shrink or fade away and become invisible. Therefore, the growth and development of uterine fibroids may rely on the synergistic effect with female estrogen.

2. The growth and development of uterine fibroids may also be related to interdependent factors. How can you say that? Because studies have shown that uterine fibroid cells carry 35% to 50% genetic abnormalities, and the fragments of chromosome 12 and chromosome 17 are exchanged, resulting in the exclusion of chromosome 12 and the loss of chromosome 17.

3. When the expression level of some cell growth factors increases, tumor symptoms will appear. They are considered to be a substance that acts as an elevating effector of ovarian growth hormone. But it cannot be ruled out because of abnormalities due to the rise of one or more diverse substances. Uterine fibroids usually contain a variety of extracellular substances. The main components of the substances are fibroblasts, and the collagen they produce is type I and type III. Uterine fibroid cells and some fibrogenic cells grow and develop under the action of various growth factors. At this time, some natural environment is also provided to promote the growth of uterine fibroid cells.
