Good after'n docs. had a breast scan. result: a simple cyst with anechoic content is seen in d liq of the right breast, diameter 7.5mm. means what pls?

Usually benign: simple cyst is a fluid filled sac usually a good sign. Anechoic means it is not echoic because it's filled with fluid and light goes through it and doesn't bounce back. (Echoic means there is probably calcification and light bounces back and that could mean trouble.) LLQ means left lower quadrant/part of your breast. You know what diameter means. (length from one edge of cyst to another)
