To prevent breast cancers, scientists look for risk factors (anything that increases your chance of developing cancer) and protective factors (anything that decreases your chance of developing cancer) starting even before birth. We can't change the genes we inherit or our age. However, some risk factors for cancer can be avoided, such as smoking.
Avoiding risk factors and increasing protective factors may lower your risk but it does not mean that you will not get breast cancer. ZBC focuses on individual and community behaviors and environments that we can change.
