Rectum Cancer surgery

Im sorry my replies arnt going thru. Thanks for the ones I have received. Thanks Clift, it was nice to hear from you. My dad is gonna be 84. Did chemo and rad last year. cancer tumor shrunk and no cancer for almost 11 months. Cancer cells are back and now we are doing surgery. Any help with the process will be great, We are scared and so is he. He is very active and doesnt want to lose that. His family will be there thru everything. Thank You and God Bless
