Tumor Suppressors

Tumor suppressor genes are parts of our DNA that help prevent the formation of tumors by controlling cell growth and division. They act like a brake on the cell cycle, stopping cells from growing uncontrollably. When these genes are damaged or mutated, their protective function is lost, which can lead to cancer. Examples include the p53 gene, often called the "guardian of the genome," as it helps repair DNA or initiate cell death if the damage is too severe. Maintaining the proper function of these genes is crucial for cancer prevention.
