Hello, my friend was diagnosed with stomach cancer a couple of months ago, they did opperations to take out the toumer, but they say the cancer is spreading, he has reciently thrown up a black subtance and he says it burned really bad, what does that mean ? does this mean he is dying?
The black stuff he is omitting is blood which usually turns black in the stomach. This is a bad sign. Meet a palliative specialist or take him to a hospice.
