- Oncogenes cause cancer by12345:
- Mutating a proto-oncogene, changing it into an oncogene, and causing the cell to divide and multiply uncontrollably13.
- Stimulating excessive cell growth and division by telling cells to make proteins that stimulate excessive cell growth and division2.
- Turning on when they are not supposed to be turned on3.
- Causing cells to grow and divide uncontrollably4.
- Promoting cellular growth by up-regulating normal genes promoting cellular growth5.

To view the original source information, use the "Learn more" links.Cancer can arise when a proto-oncogene is mutated, changing it into an oncogene and causing the cell to divide and multiply uncontrollably. Some oncogenes work like an accelerator pedal in a car, pushing a cell to divide again and again. Others work like a faulty brake in a car parked on a hill, also causing the cell to divide unchecked.www.genome.gov/genetics-glossary/OncogeneOncogenes are mutated genes whose PRESENCE can stimulate the development of cancer. When oncogenes arise in normal cells, they can contribute to the development of cancer by telling cells to make proteins that stimulate excessive cell growth and division. Oncogenes are "gain of function" genes. They gain the ability to drive non-stop growth.cisncancer.org/research/what_we_know/advances/…When a proto-oncogene mutates (changes) or there are too many copies of it, it can become turned on (activated) when it is not supposed to be, at which point it's now called an oncogene. When this happens, the cell can start to grow out of control, which might lead to cancer.www.cancer.org/cancer/understanding-cancer/gen…Oncogenes are a group of genetic mutations that may cause cancer. They’re a mutated form of genes that manage cell growth. When these genes change into oncogenes, they cause cells to grow and divide uncontrollably. Oncogenes are powerful. Cancer typically happens when several genes mutate.my.clevelandclinic.org/health/body/24949-oncogenesIf, through mutation, normal genes promoting cellular growth are up-regulated (gain-of-function mutation), they will predispose the cell to cancer; thus, they are termed "oncogenes". Usually multiple oncogenes, along with mutated apoptotic or tumor suppressor genes will all act in concert to cause cancer.en.wikipedia.org/wiki/Oncogene Oncogene: Role in Cancer, Types, and Examples - Verywell Health

Oncogene - Wikipedia
An oncogene is a gene that has the potential to cause cancer. In tumor cells, these genes are often mutated, or expressed at high levels.
Most normal cells undergo a preprogrammed rapid cell death (apoptosis) if critical functions are altered and then malfunction. Activated oncogenes can cause those cells designated for apoptosis to survive and proliferate instead. …Wikipedia · Text under CC-BY-SA licenseProto-oncogenes to Oncogenes to Cancer | Learn Science at …
