If a fibroid is found and is only 1cm in size, this is a case by case basis. If the fibroids are single, 1cm in size and located between the muscle walls, there are no symptoms and no change in menstruation, so no special treatment is needed, only regular checkups. If the fibroid is multiple, there are many fibroids, but none of them are larger than 4cm, in this case, if there are no symptoms, the menstrual flow does not increase, and there is no dripping bleeding, it is also possible to expect treatment and observation, and regular review of ultrasound is sufficient. In the case of submucosal fibroids, the growth of the fibroids into the uterine cavity will lead to increased menstrual flow and dripping bleeding, and if there is a need for fertility, the fibroids need to be treated regardless of their size. The treatment is a hysteroscopic operation, which is performed through the vagina, cervix, and into the uterine cavity to cut and remove the fibroids. However, there will be individual differences and the treatment plan will be decided on an individual basis. If you have fibroids, you need to have regular checkups, usually an ultrasound once every 3-6 months, to observe if the fibroids have increased in size, changed or increased and need further treatment.
