And many genetic, dietary, and lifestyle factors, such as smoking, may influence this process. Cancer chemoprevention uses substances to stop cancer from developing. These substances may be natural or made in a laboratory.
Why do we use clinical trials?
Researchers use clinical trials to find out whether chemoprevention substances are safe and effective in delaying or preventing cancer. Clinical trials are research studies involving volunteers. Many clinical trials have shown that certain types of chemoprevention can be beneficial.
