Uterine fibroids are common, if we look under a microscope of every woman’s uterus..probably about 75% have them!
There is no specific known cause of getting uterine fbroids, there are hormonal factors that contribute.
Genetic factors are very important in uterine fibroids, if someone in your family has a uterine fibroid, you are about 2.5 times as likely to have one too!
Monozygotic twins are more likely to get hospitalized with fibroids if their twin had them.
They are more common in twins than just in family members.
The genetic links of uterine fibroids are related to the genetic makeup of these smooth muscle tumors itself.
Some people have theorized that having periods causes lack of oxygen to the muscle wall of the uterus and affect the energy metabolism of the cells which lead to fibroids. Metabolism is a strongly linked to your overall genetics, and thus if your twin has a fibroid, you very likely do too!
