Family history of pancreatic cancer

This information explains family history of pancreatic cancer. This isn’t common, but sometimes pancreatic cancer can run in families.

Key facts

Sometimes cancers can ‘run in the family’. This isn’t common – it’s around one in ten (10%) of pancreatic cancers. In most cases pancreatic cancer does not run in families.

  • If pancreatic cancer does run in a family, there may be more than one relative with pancreatic cancer on the same side of the family.
  • Pancreatic cancer that runs in families may be caused by a change in a gene that is linked to pancreatic cancer. This gene change is known as a variant. These variants are rare.
  • Genes carry information that controls how our bodies work. We inherit genes from our parents.
  • Hereditary pancreatitis is a rare type of pancreatitis that runs in families. Pancreatitis is inflammation of the pancreas. People with hereditary pancreatitis may be more likely to get pancreatic cancer.

If pancreatic cancer runs in your family, you and your family may be able to take part in a study looking at family history of pancreatic cancer. This is called the EUROPAC study. As part of this, you and your family may be able to have regular monitoring. This aims to spot any changes to the pancreas at an early stage.

What are genes?

Genes carry the information that controls our appearance and how our bodies work. Genes come in pairs. We inherit one copy of each gene from our mother and the other from our father. We all have tiny differences in our genes that make us individual. For example, genes determine the colour of our eyes and hair.

Gene variants

Occasionally, there may be changes in genes which mean that someone is more likely to get a disease. This type of change in a gene is sometimes called a variant, fault or mutation. Having a gene variant doesn’t always mean someone will develop cancer.

Some gene variants can be passed down from a parent to a child. These are sometimes called ‘inherited’ or ‘constitutional’ gene variants.

Changes to genes can also happen during our lifetime, and these changes are not inherited or passed on. These types of changes are sometimes called ‘acquired’ or ‘somatic’ gene variants. They may be caused by a random mistake when a cell divides. Or they may be caused by other things, such as smoking. These are much more common causes of cancer than inherited gene variants.

A small number of genetic conditions are linked to an increased risk of pancreatic cancer.
