About Cancer Prevention Research Cancer prevention studies constitute one type of clinical research. These studies develop strategies for cancer prevention or cancer recurrence. This type of research involves studies in which people take a particular medicine or nutrient, eat a certain diet, or take other steps that preliminarily indicate they lower the risk of cancer.
Some studies test ways to slow down or stop cancer before it starts.
Others help people who have had cancer to stop it from coming back. Prevention studies often last many years, because it takes time to see whether cancer develops. Males and females of all ages, may be eligible to participate in cancer prevention studies. Most are healthy and have never had cancer. Studies that try to prevent second cancers include only people who have had cancer before.
