Hi, I was just recently diagnosed with BC. I am scheduled for a radiaoactive injection tomorrow and I am nervous. I've read where the pain is horrible to it's just a sting. I wanted to get some information on what to expect. I'm told I will arrive for the dye injection and then I can leave and come back in 3 hours for the imaging. My breast are still tender from the biopsy I had several weeks ago so I'm really nervous about the pain of the dye injection. Any help or information on this would be greatly appreciated. Also, any information on how long it takes to recovery from a lumpectomy. I'm scheduled for that on this Thursday and I had anticipated being back to work on Monday. Thanks
