Carcinoid Syndrome

Understanding Carcinoid Syndrome It’s common knowledge that cancer tumors can occur in different shapes and sizes. What’s less known is how they can travel at different speeds. Carcinoid tumors have been called "cancers in slow motion". They fall somewhere between a benign, nonthreatening growth and a metastatic, life-threatening growth. While the small, slow-growing neuroendocrine tumors that occur throughout the body don’t always cause symptoms, they can cause a rare condition called carcinoid syndrome.
