Yes we know that with some cancers there are genes that can increase your chance of getting the disease. Still carrying the gene increases the risk but it is not a certainty!

Genetic mutations passed from generation to generation play an important part in about 5 to 10 percent of all cancers. This means passing down of certain mutated genes from parents to kids may increase the risk of kids to developing certain cancers. But overall cancer is a complex disorder with many different factors that can cause it to occur!
