2.4cm breast lump irregular, hypoechoic heterogeneous lesion. getting biopsy. is there anything other than cancer with that description it could be?

It can still be beni: There is a fairly high chance of this one being cancer but not 100 percent. It can still be benign, so wait to worry till the biopsy results become available.Good luck.

Yes,: there are a number of benign entities that can cause a lesion with this appearance. In the absence of other descriptors, this sounds like a BIRADS category 4C lesion, which implies a 50-95% chance of malignancy.
