How accurate is a breast us on a palpable breast lump. my report says birads 2, but i still feel worried. i saw a surgeon who read over the report and said its benign. my us said 3mm hypoechoic area. no mass. to me lump feels larger than 3mm?

For a more definitive diagnostic test, obtain a referral from your physician for a digital mammogram. Your estimate of the size of the "lump" is exaggerated by your having to feel it through breast tissue and fibrocystic areas, whereas the U/S and a mammogram are focused on the lesion itself, and the size is stated according to a more precise measurement.
