Hi Amy
I don't have tissue expanders but I have a silicone implant ( I had skin sparing mast. & immed. recon. & rads wasn't on the cards then!! ) & I have just started radiation (no. 5 today) I am quietly freaking about my implant & the risk of contracture. My Rad. Onc has given me some articles to read & we will discuss them today. I know there is not much to be done to lessen the risk.......I think the only thing is she has stretched the radiation out over 28 days instead of 25 days (slightly lower dose each day, same total at the end). I still have a bit of pain across the chest & armpit so I continue to do physio a couple of times a day & figure it surely is better to keep everything as "loose" as possible. I will be curious to here what advice you are given for radiation. Good luck with your surgery.
