Twо mаjоr grоups of genes thаt become involved in the development of cаncer are proto-oncogenes and tumor suppressor genes. Proto-oncogenes become oncogenes through a [function1] change in the DNA, often in the form of a [mutation1]. Tumor suppressors can contribute to cancer when they experience a [function2] change, which is likely to happen if the gene experiences a [mutation2].
