Second Opinion on MRI Results?

SPCancer

I previously had DCIS in my right breast and have a family history of BC (mother and three maternal aunts). I recently had an MRI that showed in the left breast a "29 mm segmental, heterogeneous non-mass enhancement, increased in prominence from the prior study." Determined to be Birads 3, probably benign, six-month follow-up required. Is a second opinion warranted regarding this wait and see? The medical studies I'm reading seem to call for it.
