A 33-year-old female asked:

If a lump in the breast is detected via ultrasound, is the only solution to know if it is benign or not is by taking a biopsy?

Generally: To know what the lump is, assuming it is not a simple cyst, a biopsy is needed to get tissue from it and look at the cells under a microscope. However, the ultrasound appearance can sometimes predict what the biopsy shows, based on the presence or absence of specific findings on the ultrasound image. Please see a breast health professional to discuss options based on the particular situation.

It depends: Sometimes benign features are so characteristic on ultrasound that there is little chance of malignancy, and the lesion can be safely followed with serial imaging. Otherwise, biopsy is probably indicated.
