10 Stomach Cancer Symptoms
Symptom #2: Blood in Vomit or Stool
This is another symptom that is non-specific as other gastrointestinal conditions can also cause blood in the vomit and / or stool. However, if you start noticing that your stool looks maroon in color or tarry black, it is likely that there is blood in your stool.
However, your stool can also become darker in color if you are taking iron supplements. If it is in your vomit, it should look red and have a “coffee grounds” texture as it has been partially digested.
