An anatomical illustration of the human pancreas shows its location near the stomach and intestines, a detailed cross-section highlighting ducts and the islet of Langerhans, and an inset of pancreatic tissue histology with labeled alpha, beta, and delta cells. — pancreatic cancer The human pancreas is composed of two main types of tissue: acinar cells and islets of Langerhans. The acinar cells produce digestive enzymes, which are secreted into tiny ducts that feed into the pancreatic duct. Islets of Langerhans are clusters of cells that secrete hormones such as insulin and glucagon directly into a capillary network, which also joins the pancreatic duct.

When investigating suspected pancreatic cancer, medical professionals may perform a needle biopsy or an endoscopy to examine the organ or its cells. Because these procedures are invasive, they carry an increased risk of serious complications, most notably pancreatitis.1

Pancreatitis involves the inflammation of the pancreas, which can occur due to direct injury to the organ. Symptoms of this condition often include severe abdominal and midback pain resulting from the leakage of digestive [enzymes], tissue damage, and nerve irritation. In severe cases, pancreatitis can lead to life-threatening complications such as shock, respiratory failure, and even death.2

Due to these risks, researchers are exploring less invasive diagnostic methods, such as light-scattering spectroscopy combined with endoscope technology, to detect early precancerous lesions without the need for traditional biopsy procedures.1
