Fibroids can vary greatly in size, ranging from tiny, seed-like growths to large masses that expand the uterus. There is no single “normal” fibroid size, as many small fibroids cause few or no symptoms and may not require treatment. Fibroids smaller than 2 centimeters are generally considered small, while larger fibroids are more likely to cause heavy bleeding, pelvic pain, or pressure. The impact of a fibroid depends not only on its size but also on its location and number. For complete information, refer to USA Fibroid Centers online.
