You have the ultrasound guided biopsy scheduled? That should help identify what is there. I don’t think the description of the left lesion is definitely cancerous, but it could be.
Did they do any further investigation into the possible bone metastasis? You might want to ask bout taking a “bisphosphonate or denosumab - they can be used to strengthen bones, reduce pain, and decrease the risk of new bone metastases and fractures,” per the Mayo Clinic.

Once the biopsy comes back it should trigger further treatment, or another scan. If it is benignand because of the DCIS with a papilloma on the right, if it were me I’d want to be on a schedule for a MRI in 6 months to monitor if it is stable.

I had a 7 mm DCIS with a papilloma in my right breast (started out as 16 mm but after 2 biopsies the size was smaller after surgery). It was intermediate grade, and had a mixed cell type including some solid type, ER/PR+. The histology of the cells makes a difference for the treatment. I had a lumpectomy, radiation, and am on tamoxifen. If yours was mostly ADH with a papilloma the treatment would be different. I am not a medical professional, I’m just sharing my experience!

Are you at a comprehensive cancer center? Mayo Clinic is great, and you’ll do well there, but if you’re at a local hospital you might consider getting a second opinion from a comprehensive cancer center. It should be paid for by insurance, but if not, the fees I’ve seen aren’t too bad.
