Oral Cancer Prevention
Eating a diet high in fruits and fiber-rich vegetables may lower the risk of developing oral cancer.
Chemoprevention is the use of drugs, vitamins, or other agents to prevent or delay the growth of cancer.
Studies of chemoprevention are under way in patients at high risk for oral cancer, including those with precancerous oral lesions and those with a history of oral cancer. Check NCI's Cancer Clinical Trials Registry for chemoprevention trials for cancer of the lip and oral cavity and oropharynx.
Cancer prevention clinical trials are used to study ways to prevent cancer.
Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer.
The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements.
New ways to prevent oral cancer are being studied in clinical trials.
Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI Web site. Check NCI's PDQ Cancer Clinical Trials Registry for lip and oral cavity cancer prevention trials and oropharyngeal cancer prevention trials that are now accepting patients.
