Active_comparator: Familial pancreas cancer relatives

High Risk Group 2 (familial pancreatic cancer relatives):~1. \> 55 years old or 10 years younger than the age of youngest relative with pancreatic cancer, and~2. come from a family with 2 or more members with a history of pancreatic cancer (2 of which have a first-degree relationship consistent with familial pancreatic cancer), and~3. have a first-degree relationship with at least one of the relatives with pancreatic cancer.~If there are 2 or more affected blood relatives, at least 1 must be a first-degree relative of the individual being screened

Active_comparator: Group 1 germline mutation carrier

High Risk Group 3 (Group 1 germline mutation carriers with an associated with an estimated lifetime risk of pancreatic cancer of \~10% or higher):~a. \> 50 years old or 10 years younger than the age of the youngest relative affected, if pancreatic cancer is in family, and b. The Patient is a carrier of a confirmed BRCA2, ATM or PALB2 mutation, regardless of family history of pancreatic cancer. b.\> Individual is a carrier of a confirmed FAMMM (p16/CDKN2A) mutation, age 40 years or older, regardless of family history of pancreas cancer.

Active_comparator: Group 2 germline mutation carrier

High Risk Group 4 (Group 2 germline mutation carriers with an associated with an estimated lifetime risk of pancreatic cancer of \~5%):~1. \> 50 years old or 10 years younger than the age of the youngest relative with pancreatic cancer, and~2. The patient is a carrier of a confirmed BRCA1 or HNPCC (hereditary non-polyposis colorectal cancer or Lynch syndrome, hMLH1, hMSH2, PMS1, hMSH6, EpCAM) gene mutation, and there is \> 1 pancreatic cancer in the family, one of whom is a first- or second-degree relative of the subject to be screened.

Active_comparator: Hereditary pancreatitis

High risk group 5 (hereditary pancreatitis) with confirmed gene mutations that predispose to chronic pancreatitis, such as PRSS1, PRSS2, CTRC) and age 50 years or older (these patients have an estimated lifetime risk for pancreatic cancer of 40%) or twenty-years since their first attack of pancreatitis, whichever age is younger.

Active_comparator: Peutz-Jeghers Syndrome

1. At least 30 years old, and~2. at least 2 of 3 criteria diagnostic of Peutz-Jeghers syndrome (characteristic intestinal hamartomatous polyps, mucocutaneous melanin deposition, or family history of Peutz-Jeghers syndrome), or,~3. known STK11 gene mutation carrier

Active_comparator: Negative control

1. are undergoing routine EGD or Colonoscopy; or Endoscopic Ultrasound (EUS) and/or Endoscopic Retrograde Cholangiopancreatography (ERCP) for non-pancreatic indications as part of their standard medical care, and~2. have no clinical or radiologic suspicion of pancreatic disease (chronic pancreatitis or pancreatic cancer)

Active_comparator: Chronic Pancreatitis

Active_comparator: Pancreas cancer

a. are undergoing EUS and/or ERCP for evaluation and/or treatment of suspected or proven pancreatic ductal adenocarcinoma (based on clinical and radiologic evidence)

Active_comparator: Pancreas cyst, IPMN evaluation

are undergoing EUS and/or ERCP for evaluation and/or treatment of suspected or proven pancreatic cancer precursor, intraductal papillary mucinous neoplasm (based on clinical presentation and radiologic or prior EUS or radiologic evidence of a dilated main pancreatic duct and/or pancreatic cystic lesion communicating with the pancreatic ductal system).
