Cancer research is the scientific study aimed at understanding how cancer develops, spreads, and can be treated. Researchers investigate the biology of cancer cells, looking for ways to stop their growth and spread. This includes studying the effects of different treatments, such as chemotherapy and radiation therapy, to find the most effective options for patients. In addition to treatment, cancer research also focuses on prevention and early detection. Scientists explore factors that may increase the risk of cancer, like genetics and lifestyle choices. By understanding these factors, researchers hope to develop strategies that can help people avoid cancer or catch it early when it is most treatable.
