Nodules are growths or raised lumps made up of inflamed tissue and occasionally fluid, according to Healthline.com. Nodules form on organs such as the pancreas and are usually not cancerous, although sometimes they may be a sign of an underlying health condition.
The pancreas is an organ in the abdomen which produces fluids that help digest food. Pancreatic growths such as nodules or cysts may be discovered when imaging tests are performed. The Mayo Clinic states that doctors often test a sample from the growth to deduce whether it is associated with cancer or another disease. Nodules may need to be surgically removed, or they may be left alone and monitored over time to ensure they are not getting bigger or impairing pancreas function.
