My husband cancer was discovered at grade 3 well differentiated stage 4. He was also given 6 months and that was June of 2022. His metastasized to his liver and he has an unchanged spot on his spine. It is two years later and he is doing quite well. He has been able to enjoy retirement and the birth of two more grandchildren. His energy level is low but he is able to do a lot now. It is a difficult process but the science is always advancing. My best to you.
