Hang in there. My wife literally finished treatments for breast cancer 2 weeks ago. It was not a fun time but it's pretty amazing the amount of support given by friends, family and organizations like the American Cancer Society. The good news is they are light years ahead of where they were 10 years. There are so many more effective treatments today and new options and treatment regimens are coming out every day. Still, I hope your mom doesn't have to re-live life with cancer again. Once is plenty. Positive thoughts her way!
