Tumor suppressor gene a tumor suppressor gene or anti-oncogene is a gene that reduces the probability that a cell in a multicellular organism will turn into a cancer cell when tumor suppressor genes are altered or inactivated (due to a mutation), they lost the ability to make a protein that controls cell growth.

The tumor suppressor genes (some times called anti-oncogenes) stops the cells from dividing it is known that many cancers inhibit the tumor stressor genes from performing their functions leading to rapid growth of the cancerous cells. Another gene, known as the retinoblastoma gene (rb), is also inactivated in many tumors and represents the first isolation of a tumor suppressor gene  so called because it was first studied in the inheritance of retinoblastoma, rb gene functions as a cell cycle regulator.
