Abnormal Routine Mammogram - Help Understanding

Any insight here is appreciated! I am 44 years old. Had one mammogram when I was 36 after dr. thought she felt something, but after mammogram all was great - breast mostly fatty. Having some other female issues and dr. was on me to get mammogram done due to age and time since first only one. So I did today. Before I ever left the parking lot, I had a call from my doctor saying I needed a diagnostic mammogram done. Here's some excerpts from the screening mammogram:

The focal asymmetry in the left breast lower inner aspect middle depth is indeterminate.

There are scattered fibroglandular elements in both breasts. (wasn't like that 8 years ago; was fatty).

There are multiple asymmetries in the right breast upper outer aspect middle depth.

Anyone else have similar findings? Any insights on how concerning this might or might not be?

Thanks in advance for any responses.
