Promising cancer research often shows initial success in animal models, particularly mice, but many of these studies do not translate to effective treatments in humans. Each type of cancer is unique and responds differently to treatments, complicating the development of universal therapies. For instance, lung cancer has distinct types that require tailored approaches. While some studies aimed at enhancing the immune system's ability to target cancer cells have shown potential, they have not consistently yielded successful outcomes. Current trends in research focus on personalizing treatment based on genetic mutations of tumors. Preventive measures, such as anti-smoking policies and vaccines like the HPV vaccine, are also highlighted as effective strategies in reducing cancer incidence. Overall, while there are numerous studies that initially appear promising, many have ultimately failed in human trials, underscoring the complexity of cancer treatment.
