Can late-stage pancreatic cancer cause vomiting blood?
For patients with advanced pancreatic cancer, there is a possibility of vomiting blood.
Vomiting blood is one of the manifestations of upper gastrointestinal bleeding. In some cases, patients with pancreatic cancer may experience upper gastrointestinal bleeding:
1. Stress ulcers, in patients with advanced tumors, sometimes occur due to extreme physical debilitation, leading to stress ulcers. These ulcers cause localized erosion of the gastric mucosa, eventually leading to bleeding;
2. Thrombocytopenia, for patients with advanced pancreatic cancer, most need to undergo systemic chemotherapy. Chemotherapy can suppress the function of the bone marrow, leading to a reduction in peripheral white blood cells and platelets. When platelets decrease to a certain level, the body's clotting functions may be impaired, concurrently leading to upper gastrointestinal bleeding.
