Appearance Fibroids are usually firm round lumps that occur in the uterus. They can be as small as a pea or as large as an apple, or even a cantaloupe. Fibroids usually increase the size of your uterus. During a pelvic exam, your health care provider may notice if your uterus is unusually large. And, if a fibroid grows near the outer surface of the uterus, your provider may be able to feel a bump or knob during your pelvic exam.
