Quick Answer: Is family history a risk factor for cancer?

Why is family history a risk factor for cancer?

The more relatives who have had the same or related types of cancer, and the younger they were at diagnosis, the stronger someone’s family history is. This means that it is more likely that the cancers are being caused by an inherited faulty gene.

Can cancer be inherited from family?

Although cancer is common, only 5-10% of it is hereditary, meaning an individual has inherited an increased risk for cancer from one of their parents. This inherited risk for cancer is caused by a small change (called a mutation) in a gene, which can be passed from one generation to the next in a family.

Can cancer ever be cured?

There are no cures for any kinds of cancer, but there are treatments that may cure you. Many people are treated for cancer, live out the rest of their life, and die of other causes.
