Pancreatic Cancer

Pancreatic cancer is a highly lethal malignancy, predominantly composed of pancreatic ductal adenocarcinoma, which accounts for 80–90% of cases and is characterized by insidious onset, rapid progression, and a low rate of early diagnosis, resulting in poor treatment outcomes. It originates from abnormal cell growth in the pancreas, a gland located between the stomach and spine, with the exocrine type being more common and typically diagnosed at an advanced stage, while neuroendocrine tumors (islet cell tumors) are less frequent but associated with a better prognosis. Risk factors include age (most commonly diagnosed in individuals aged 65–74), type 1 and type 2 diabetes, and other unknown genetic or environmental influences. Symptoms such as jaundice, nausea, bloating, fatigue, and loss of appetite often appear late in the disease course. Treatment options include surgery, chemotherapy, and radiation therapy, yet the overall 5-year survival rate remains low, ranging from 5% to 15% in the United States.
