Biopsy cancelled and now MRI needed?

Hi everyone, would appreciate some perspective here.

46 yo female, have gotten annual 3D mammograms since age 40. Have gotten several callbacks for ultrasounds over the years, but all checked out.

My screening mammogram found a new, low-density circumscribed slightly lobulated mass in upper outer mid left breast. No additional areas of concern found. I have dense breasts.

Extensive ultrasound was performed, but no suspicious cystic or solid mass was found, and no focal shadowing or distortion. Was referred for a biopsy.

Yesterday I went for the biopsy. It was the 3D Affirm stereotactic needle core biopsy. The biopsy never happened - the report language reads "routine preprocedure imaging was performed and failed to confidently reproduce the mass...Therefore 3D ML, MLD, and spot compression views were obtained. These repeat images failed to confidently reproduce the mass in orthogonal planes, especially on the spot compression views. Therefore, since the mammogram finding was felt to be somewhat equivocal, biopsy was cancelled. Recommend breast MRI with and without gadolinium for further evaluation." The final assessment is 0 - incomplete, but I was told it was a BI-RAD 4 (since that daignosis is needed to warrant a breast MRI).

I now have several more weeks until I can get in for the MRI, which sucks. It's already been a month since my mammogram.

However, given my reports to date, am I wrong to think that this is likely to be a benign mass? Should I push back on the MRI and ask instead for another mammogram in a few months? Thanks for any insight!
