Genetics are known to play a role in your risk for cancer, but your parents' age when they were diagnosed is also a factor.
A new study looked at medical data collected from nearly 12 million people living in Sweden.
Researchers found people who had the highest risk for developing the same cancer as their parents, had parents who were diagnosed at a young age; however, people whose parents were 80-years old or older when they were diagnosed also had an increased risk.
They say knowing this information could encourage people to make healthier choices so they can avoid the cancer their mother or father developed.
