What is ENT - What are tumor suppressor genes, oncogenes, and proto-oncogenes?
A proto-oncogene is a normal gene that, when altered, can help produce cancer. An oncogene is a gene that has the potential to cause cancer. A gene known as a tumor suppressor prevents a cell from developing into cancer. When paired with protooncogene and oncogene overexpression, mutations in tumor suppressor genes that result in loss of function may enable the cell to develop into cancer.
