Thanks for the advice guys. My dad was dx in January with stomach cancer to the liver. After 5 treatments the doctor said what little that was left was most likely scar tissue. A endoscope confirmed that there was no cancer left.That was in May. A CT scan in July showed no change.We are waiting for results from a scan last week. I am worried that the cancer is back because he has been having stomach pain again. He has been on 20 seeds a day and cut down to 2 b17 pills a day.
