Dear marjay: I would pay less attention to "other women" and more attention to your doctor. An ultrasound is a test that is often used to differentiate a solid versus cystic mass. If the mass is cystic (fluid filled), it can generally be left alone. If the mass appears solid, further investigation is needed. The doctor may be more or less suspicious of a mass on any image (ultrasound or mammogram) but the only way to know for sure is with a biopsy.
