Pancreas is located in the abdomen behind the stomach. When cancerous cells form in the tissues of the pancreas, it is pancreatic cancer. There are two types of tumors in pancreas, exocrine tumor and endocrine tumor. Both are very different from each other in terms of risk factors, causes, symptoms and their treatment also varies. However, exocrine cancer is the most common type of pancreatic cancer.
And more than 80% of exocrine pancreatic cancers are adenocarcinomas, out of which nearly all of these are ductal adenocarcinomas. They usually start in the cells lining the ducts of the pancreas. Other rare types of cancer of pancreas are pancreatoblastoma, sarcomas of the pancreas and lymphoma.
Pancreatic cancer affects 1 per 100,000 people per year globally. It is an aggressive and fast-growing disease. Patients can die within a few years after diagnosis if not treated on time.
Although incidences of pancreatic cancer are less common in India compared to western countries, in the recent past more number of pancreatic cancer cases have been reported in the country.
