I will say this is , even more aggressive then TNBC .Here survival is about a year , less with MM ( malignant melanoma ) and pancreas, maybe now with different drugs improve a little , but is very deadly.

His friend father is stage 4 MM , tomorrow to call Dr NP is my advise...
And there is a chance to improve , with what we know about CCR5 in MM , and Leronlimab.
