Cancer can cause abdominal pain through several mechanisms:
Direct pressure: Tumors can exert pressure on surrounding tissues and organs, leading to discomfort and pain. Obstruction: Tumors in the digestive tract can cause blockages, leading to pain, nausea, and vomiting. Metastasis: Cancer spreading to other organs such as the liver or peritoneum can cause referred pain. Inflammation: Some cancers cause inflammation in the abdominal cavity, contributing to pain.
