Im not 100% sure but I think it is to measure the radiation to make sure the dose is correct
I think it’s to improve targeting the dosage to where it’s needed, instead of the blanket coverage I got. BUT you’ve just got time to ring one of the nurses here to ask OR ring your radiotherapy department - you’ll fret all weekend otherwise!
Really I just wanted to sympathise with you regarding chemo-brain. It’s a b***** isn’t it! Information comes in, is processed and you know you understand and, a minute later, it’s gone. I’m 5 months past chemo and I still suffer. You have more delights ahead, like chemo-curl, which is distinctly unflattering, and the thickest eyelashes you ever had (they don’t last, unfortunately). So good luck with the rads (I found it a doddle but chemo was terrible) and the rest of the treatment.
Just had my second session and today they told me they had been asked by the Dr to use some extra equipment. They stuck 3 probes onto my skin around my affected area. I did try to ask the radiologists but I cant think or remember what they said. My poor brain doesnt work well since having chemo.
