And then they become mutations, which may eventually lead to cancer. This is especially true if the mutation occurs in a tumor suppressor gene or oncogene. Mutations in DNA repair genes can be inherited, such as with Lynch syndrome, or acquired. Despite all that is known about the different ways cancer genes work, many cancers cannot be linked to a specific gene.
