Vomiting
In some cases, the nauseous reflex becomes severe enough to cause vomiting as well. It is more common when the tumor has grown inside the intestinal lumen and starts to block the normal passage of the stools throughout the gut. In some cases, the tumor might also exert pressure to the adjacent bowel and cause the same obstructive symptoms. When the problem is severe enough, it may even lead to fecal vomiting and a severe compromise to the patient’s health.
