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.

Early diagnosis is critical for pancreatic cancer survival because the disease is often asymptomatic until it reaches an advanced stage, at which point treatment options are limited and the prognosis is poor.12

Because symptoms typically do not appear until the cancer has progressed, the overall five-year survival rate remains extremely low. However, patients who are diagnosed early in the course of the disease experience significantly higher survival rates. Early detection allows for the possibility of surgical intervention, which is generally reserved for localized cases where there is a reasonable chance of curing the disease.134

Because traditional diagnostic procedures like needle biopsies are invasive and carry risks, researchers are currently focused on identifying specific biomarkers and utilizing advanced imaging techniques, such as light-scattering spectroscopy, to detect precancerous lesions before the cancer spreads to lymph nodes or other organs.1
