Hi Agnes, I have to sincerely admit I do not much understand the thing about the thyroid hormones. Is it good or bad? I would say that if you would not need to take the meds anymore, it is alright? But the test should approve it?
About the breast lump. Hm, I had a problem some time ago (last year) with it too. All of a sudden a breast lump appeared in my left one and I immediately had to go to the specialized mammo center where they did an ultrasound and the doctor did not like it at all so they scheduled me right for next day for a biopsy. It was not anything pleasant, I have to say but it wasn't anything horrible (definitely less horrible then yesterday's two urological tests - quite painful). Fortunately it was benign too but the doctor said she does not like it at all anyway - mainly the speed in which it grew etc. So I have to recheck every 6 months. I try to take it as an advantage - because unlike other girls I have far bigger chance to find out about possible problem right early - not late. (In my country only after you are 50 you can have the breast checks covered by insurance. Otherwise it costs few thousands. Unless it is required from your gynecologist but that does not happen often).
Please do not worry much. I can fully understand your worries for myself, and imagine - my mom gets such lumps from time to time, they form and then they disappear slowly again.
Big hugs!!!
