I started a new post earlier this week titled "Obdivo and Yervoy Regimen."  My significant other is at the end of the regimen of Opdivo and Yervoy (it has been 3 months of both of those, every 3 weeks), and they are starting him with a new regimen of 5 treatments of just Opdivo.  We met yesterday with the oncologist to get the PET scan results.  Unfortunately, the tumor in his stomach has grown.  The oncologist will be meeting with the cancer board of the hospital and will get back tu us.  We are not sure if the tumor can be operated on since it is now so large.  The doctor was very surprised since with such a large tumor, she would think that he would be in much greater pain.  We are told to hope for the best but prepare for the worst..  Has anyone dealt with melanoma that moved from the original location to the stomach?  My S.O. was first diagnosed with melanoma about 6 years ago (on his back) and they biopsied and cut a margin and removed it, with a couple of lymph nodes, and 5 years thereafter, said everything looked good.  Then earlier this year, we were informed that the cancer had moved from the back to his stomach.
