Vasoactive intestinal peptide (VIP) tumor is a rare type of neuroendocrine tumor that produces high levels of the hormone VIP. This hormone can cause symptoms such as watery diarrhea, abdominal pain, and low blood pressure. VIP tumors can occur in various parts of the body, including the pancreas, small intestine, and lungs. Diagnosis is typically made through imaging studies and biopsy. Treatment options may include surgery, radiation therapy, and chemotherapy. The choice of treatment depends on the size and location of the tumor and the overall health of the patient. It is important to seek medical attention if you experience symptoms that may be related to a VIP tumor.
