Cancer is a disease in which abnormal cells grow uncontrollably and may spread to other parts of the body. It can affect almost any organ or tissue and is caused by genetic mutations, environmental factors, lifestyle habits, infections, or inherited conditions. Clinical and translational cancer research focuses on understanding the molecular mechanisms of cancer development, improving early detection, developing advanced diagnostic tools, and evaluating innovative treatments such as targeted therapy, immunotherapy, chemotherapy, radiation therapy, and precision medicine. Ongoing research also emphasizes cancer prevention, personalized treatment strategies, survivorship, and improving patients' quality of life. Through continuous scientific advancements and multidisciplinary collaboration, cancer research aims to reduce the global burden of cancer and improve survival outcomes.
