Pancreatic cancer cells. Coloured scanning electron micrograph (SEM) of pancreatic cancer cells. The cells are joined by a cytoplasmic bridge. The irregular shape of the cells, the cellular projections and blebs (nodules) are typical of cancer cells. Pancreatic cancer often causes no symptoms until it is well established and untreatable.
