Pancreatic cancer is a cancer that begins in the tissues of pancreas. The two types of pancreatic cancer are adenocarcinoma (cancer that forms in the pancreas ducts) and endocrine cancer (cancer that forms in the hormone-producing cells).
The cancer occurs when cells in the pancreas develop genetic mutations. These mutations cause cells to grow uncontrollably and to continue living after normal cells would die. These accumulations of cells can form a tumour.
Signs and symptoms often do not occur until the disease is advanced.
No standard screening exists for pancreatic cancer.
