Nodular enhancing foci along scar tissue INSIDE breast after surgery

I had an MRI with contrast at my one year follow-up in October after a right DCIS BCS with reduction and mastoplexy on left breast. Radiation VMAT for one week, and currently on Tamoxifen. I’m 69 year old.
The MRI shows asymmetric nodular enhancing foci along the curvilinear scar within the central left breast. This is inside the breast - not the scar line on the external skin. It says it is likely related to rearrangement of the internal glandular tissue, BI-RAD 3. Anyone else have this type of “foci”? What was your follow-up experience?
I’m scheduled for another MRI and mammogram in 6 months. Not much else can be done, but it is a worry that pops up every so often.

Also, there is a level one axillary node that is round that they are watching. This is the side where I had the DCIS in the LOQ. They see no sign of malignancy but it concerns me because of the location and that it is a unilateral node issue, not bilateral which would be more likely if it was just inflammation. Any thoughts on this would be helpful, too.
These are somewhat minor issues that I know I should set aside for 6 months. I do a pretty good job of that until something triggers my BC worries.
