Confused about different types of dye used?

I can't help you fully with this, my thoughts are, maybe this is the actual 'brand name' they use.

I had 'blue' dye (private).  It seemed minimal, I have read many of the Fruit Loops have talked about becoming Smurfs and having 'blue wee' for a few days - I didn't have this happen.

I'm in London and had mine on the NHS. They injected a radioactive substance into my nipple (yes,  ouch!) before surgery and I lay for about 20 minutes while they filmed its progress to my nodes.  The surgeon injected blue dye once I was in theatre.  I saw the surgeons report which gave the size of the sentinels and how 'hot' (radioactive) and blue they were.  Because I had a mastectomy I didn't have the  Smurf look though!

Hi Magtie, it seems like so many things, that different places do it differently. In my case I had no pre op injection so the blue dye injection must have been done in theatre. Everything that came out down below was blue afterwards! And I had a blue patch on my breast for many months as well. Quite the rainbow look as I had a lot of bruising too. It has always niggled me that I clearly didn't have the radioactive injection, and didn't know anything about it until I joined this forum after the op. So it's good you're looking into it all now. I don't know the pros and cons. Try not to stress about it all (easy to say, I know), but regard it as good to know beforehand and good to make as informed a choice as possible. I think we all felt better once the treatment started, it's so horrible being in the pre treatment 'limbo'.

Love and a big virtual hug, HFxx
