Thyroid and breast cysts

Back in 2011 I had the right half of my thyroid removed as well as a 2cm nodule that contained hurthel cells, with metaplasia..  I've been on levothrixine 100mg and armour 15mg.  Blood work and tsh levels have been good since on armour.   This week I had my first mammogram and have to go back in for additional projections. Np said looks like it may be fib. Cysts.  Does anyone hav any information about these two issues being linked?  Can I just say I'm tired of doctor's offices.   (Fractured my wrist last year pretty bad, so at ortho. A lot)
