What is which size of fibroid is dangerous in mm?

Fibroid size and "danger" are not directly correlated. The location and number of fibroids, as well as the presence and severity of symptoms, are more important than the size itself. However, generally speaking:

• Small fibroids (under 10 mm or 1 cm): These are usually asymptomatic and don't require treatment. They are often monitored over time.

• Medium fibroids (10 mm - 50 mm or 1 cm - 5 cm): These may or may not cause symptoms. The severity of symptoms will determine the treatment plan.

• Large fibroids (over 50 mm or 5 cm): These are more likely to cause symptoms due to their size and potential to press on surrounding organs. They are more likely to require treatment.

The key is that "dangerous" in the context of fibroids refers to the impact on a woman's health and quality of life. Large fibroids can cause:

• Heavy and prolonged menstrual bleeding (leading to anemia)
• Pelvic pain and pressure
• Frequent urination
• Constipation
• Back pain
• Infertility or pregnancy complications (though this is less common)

Treatment options vary and depend on the size, location, number of fibroids, symptoms, and the woman's desire for future fertility. Some options include medication, uterine%20fibroid%20embolization, myomectomy (surgical removal of fibroids), and hysterectomy (removal of the uterus). It is important to consult with a doctor about your specific situation.
