Proto-oncogenes are normal genes that help regulate cell growth and division. When mutated or altered, they can become oncogenes, which promote uncontrolled cell growth and can lead to cancer. The main difference is that proto-oncogenes are normal genes that can become oncogenes through mutations.
They are called oncogenes.
Proto-oncogenes stop cells dividing too often. When a mutation occurs to proto-oncogenes this is when cancer can occur, as there is then no hay-flick limit (normally cells have a limit to how many times then can divide) cells are able to replicate uncontrollably.

False. Proto-oncogenes are genes that can potentially become oncogenes, which are associated with cancer development. They are present in all individuals, not just those with cancer.
The best place that one can learn more about oncogenes is the American Cancer Society's official website. The site has a page dedicated to oncogenes and has a list of answers to common questions asked about the gene.
