The question of whether a fibroid of 55 mm requires surgery needs to be looked at individually. If a woman who is prone to pregnancy has fertility requirements and has a five centimeter fibroid, surgery is recommended first. This is because fibroids may interfere with pregnancy during pregnancy preparation. During pregnancy, fibroids may increase in size and even degenerate, causing abdominal pain and requiring emergency surgery, and they may also cause miscarriage and premature birth. Therefore, for women who are prone to pregnancy, surgery is recommended for fibroids of five centimeters, and normal preparation for pregnancy should be considered after two years. For women who are approaching menopause and in their 40s, a five-centimeter fibroid without any symptoms can be treated without surgery and can be observed first. In the case of women in their 40s, fibroids causing clinical symptoms such as abnormal menstrual flow, increased menstrual flow, anemia, and increased fibroids pressing forward on the bladder causing frequent urination and backward on the rectum causing constipation also require surgical treatment.
