Like "I am very sorry to hear of the cancer. I am glad you are over all those nasty treatments, I know they are rough. I watched some loved ones go through that. I have a friend right now, going through her last chemo treatments, for lymphoma she is going to be okay they say it is curable and another friend is over her colon cancer. Glad you are cancer free now, and I sincerely hope and pray that you stay that way! welcome back!"
