Tumor suppressor genes

Tumor suppressor genes are a type of gene that help prevent cells from growing uncontrollably and forming tumors. They act like the body's natural defense system, checking cell division and repairing DNA damage. When these genes function properly, they reduce the risk of cancer. However, if tumor suppressor genes become damaged or inactive due to mutations, cells can start to grow unchecked, increasing the likelihood of cancer development. They are essential for maintaining healthy cell growth and preventing the formation of abnormal cell masses.
