Dear mg2,
I had mastectomy, chemo and then Radiotherapy (5weeks) and now Letrazole for 5-10yrs.
You are going from surgery to Radiotherapy. I'm sure that they would want you healed well first.
I strongly recommend Mepitel. You could not tell that I had radiotherapy, no marks, burns or reaction.
It took a bit to get used to wearing it as it feels like a plastic. It looks like Opsite or Tegaderm, if you had seen them.
If your place for radiotherapy offers it, I recommend that you do.
It is worn 24/7. I was told that the 'burning' does not only happen during the 5-10 mins that R/T is given.
The explanation was that the Mepitel keeps the skins own moisture in, and protects the skin from the friction of clothing and bedding. The nurses replaced it as needed, when it sometimes lifted and rolled back.
Some of my Mepitel lasted 2 1/2 weeks on. The area under arm seemed to need replacing more often.
