There is no specific value for how much normal fibroids grow each year. Some fibroids grow slowly and will not exceed 1cm per year which is considered normal, while some fibroids grow slowly but show symptoms, which is not normal. Uterine fibroids are benign tumors, most of which have no conscious symptoms and are often found during a physical examination. Some fibroids will grow, but the growth rate is very slow. If there are no symptoms, they can be examined every 6 to 12 months according to the specific situation. If the growth is not more than 1cm per year, and there are no clinical symptoms, this situation is considered normal, and you can continue to observe. There are some uterine fibroids that grow slowly but show symptoms such as increased menstrual flow, long duration of each menstrual period, irregular bleeding during non-menstrual period, etc. This situation is abnormal and surgical treatment is recommended. You should not judge the extent of the disease solely on the basis of the growth rate of fibroids, but should combine the clinical symptoms and examination results to make a comprehensive judgment, go to the hospital on time for review, and deal with the situation accordingly.
