How does myoma occur?

 

Uterine fibroids (myomas) are formed as a result of abnormal proliferation of cells belonging to the muscle tissue of the uterus called myometrium. These lumps are found in about one-third of women of childbearing age. ​ ​

 

As with other benign and malignant tumors in our body, the true cause of fibroids is not known exactly. However, genetic and hormonal factors are thought to play an important role.
