[|Human|] My dad was recently diagnosed with stage 4 pancreatic cancer that has also spread to the liver . The cancer in size are the size of a grain of rice. I have seen charts where cancer starts out like a grain of rice,pea,grape ect.. all the way up to a golf ball. So my question is : Does the size of the cancer mean that he has a greater chance of survival with treatment now because the cancer is still so small? Or in a stage 4 diapnoses the size of the cancer doesn t matter.....
[|AI|]  Hi, In some sort of cancer even in stage 4 cancer there is chance of complete cure. But unfortunately pancreatic cancer is not of this category. Stage 4 disease has guarded prognosis. Now some more information will be helpful like his liver function test, no. of liver metastasis, routine blood test to have a more elaborate discussion. Anyway size of primary in pancreas matters little in the setting of metastatic disease. Consult your doctor.
