When I searched for radioactive ion injection in the cancer chats prior to having it done there were no results so I am writing this in case any one else does a similar search. I have invasive breast cancer grade 2 and initially had a lumpectomy done as it was thought I just had DCIS. Once the invasive cancer was discovered I had to have a Sentinel node removal (which I had on Monday) to see if it has spread. I was very very anxious about having to have the radioactive injection in my breast so for anyone else about to have it this is my experience;

the first thing to be clear about is no one can tell you what the level of discomfort/stinging is likely to be because everyone will feel it in their own unique way. The most important thing to share with you is that the whole process is incredibly short , the actual insertion of the needle and the injection of the ion itself took less than a minute- so only seconds- read that again - only seconds. It is very very quick. The needle was inserted into the edge of the aureola not actually into the nipple itself as I had thought. The nurse was wonderful and explained every step of the process. Because my nipple has lost some sensitivity post surgery I actually didn't feel anything, most people feel some stinging I was told. It really wasn't the awful experience I was anticipating. I cried with relief when it was done because I had got so hyped up about it. My nipple and breast area is tender today and I am using ouch cream (from blended therapies ) which is amazingly soothing. Hope this helps someone!
