Yes, I would agree Eagle. When they thought my mom had cancer they said they could do blood tests to check for "marker" chemicals that tell them it is likely to be cancer and I think even what type of cancer. I don't understand why they couldn't do this for your mom and brother. I would think that even if these are special blood tests, they would not be extremely expensive. Perhaps they are not good enough yet to be 100% reliable.

Dotsie, I can't remember for sure, but I believe they gave my mom 6 - 12 months and she lasted almost 18.
