Pancreatic cancer, which is the disease that took the life of the Queen of Soul, Aretha Franklin, is considered to be incurable. Many people who have the disease generally have a 5-10 percent chance of recovery. The chances tend to be even lower for someone of older and overweight.
What Causes Pancreatic Cancer?
As with many types of cancer, the causes of pancreatic cancer are simply not known. Although certain pancreatic cancer risk factors have been identified, there is no complete understanding of the disease.
Pancreatic cancer develops when a cell in the pancreas acquires damage to its DNA that causes it to behave and multiply abnormally (no one knows exactly how this process happens). A single cancer cell grows and divides rapidly, becoming a tumor that does not respect normal boundaries in the body. Eventually, cells from the tumor can travel elsewhere in the body (metastasize) through the blood or lymphatic system.
Some of these mutations happen randomly. Others occur in response to things we do or experience in the environment. Some may be inherited.
