Quick Answer: Do cancers skip a generation?

The mutation is passed down in a Mandelian fashion, which means a parent (either father or mother) who carries the mutation has a 50% chance of passing it to their children. Fathers may be unaffected clinically but act as carriers and can pass the mutation to their children. The cancer therefore may skip a generation.

What cancers are hereditary?

Why can cancer itself not be inherited?

Cancer’s genetic component comes from mutated DNA. And you inherit DNA from your parents, who inherited DNA from their parents, and so on. You cannot inherit cancer itself, but you can inherit the gene mutation that damages the cells. And that gene mutation can increase your risk of developing cancer.
