Esophageal Cancer Prevention (PDQ®): Prevention - Patient Information [NCI] - What is prevention?
Cancer prevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. Hopefully, this will lower the number of deaths caused by cancer.
To prevent new cancers from starting, scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a cancer risk factor; anything that decreases your chance of developing cancer is called a cancer protective factor.
No clinical studies (i.e., clinical trials, case series, or case reports) have been reported in peer-reviewed scientific journals to support the safety or the efficacy of 714-X. A number of anecdotal reports and testimonials have been published in newspapers and other nonmedical literature. The producers of 714-X state that they have tried to document the long-term experience of patients treated with this compound, but they have encountered difficulty in obtaining information from patients and their...
Some risk factors for cancer can be avoided, but many cannot. For example, both smoking and inheriting certain genes are risk factors for some types of cancer, but only smoking can be avoided. Regular exercise and a healthy diet may be protective factors for some types of cancer. Avoiding risk factors and increasing protective factors may lower your risk but it does not mean that you will not get cancer.
Different ways to prevent cancer are being studied, including:
Changing lifestyle or eating habits.
Avoiding things known to cause cancer.
Taking medicines to treat a precancerous condition or to keep cancer from starting.
