Cervical Cancer Prevention
Regular pelvic exams and Pap tests help find abnormalcells in the cervix before cancer develops. However, test and procedures that may be used after an abnormal pelvic exam or Pap test result have risks. For example, the treatment of low-gradelesions may affect a woman's ability to become pregnant or carry a baby to full term. In women younger than 25 years, screening with the Pap test has more risks than benefits. Screening with the Pap test is not helpful in women older than 60 years who have had recent negative Pap tests. (See the PDQ summary on Cervical Cancer Screening for more information.)
The effect of diet on cervical cancer risk is not known.
Cancer prevention clinical trials are used to study ways to prevent cancer.
Cancer preventionclinical 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 cervical 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 cervical cancer prevention trials that are now accepting patients.
