Does Hyperthyroid Diagnosis Equal Higher Breast Cancer Risk?

I also take both T4 and T3 . I'm on 200mcg of thyroxine daily and I take 20mg tertroxin at around 2pm which just gives me a pick me up in the afternoons. I used to be on 500mcg of T4 daily and 40mg tertroxin daily. This is why my levels are checked frequently because my body changes it's mind on whether it's going to absorb the meds or not. All very scary when you end up with a thyroid storm because it's decided that today I will absorb everything thanks very much. If only this body of mine would comply all the time!
