Peripheral flow noted on Doppler is usually a good sign, however abnormal lymph node combined with hypoechoic nodules on the same side requires biopsy to rule out cancer (about 20% chance) it is very good idea to take sample from lymph node itself. As alternative (or complimentary) to this a newer type of ultrasound can be used to accurately predict the chance of cancer.
Thanks for the info. I discuss the results with my doctor on Friday. Unfortunately, having time to research the report on the internet has made me a little nervous!
