Tough call, seems like my family has been a breeding ground for cancer. Some have had chemo and radiation, some have added surgery to those. Currently I have a sister that has been receiving chemo for the past 2 years. At times, she'll say that's all but when it comes time for another treatment, she goes for it. Ny oldest just finished up with chemo and got a report that there is no detectable sign of cancer. Guess it all boils down to a private conversation between the patient and the Dr. Hoping for the best with your Mom and your family. It can be rough.
