Genetic tests can reveal whether you are at risk for certain cancers, but will this information help you to help prevent cancer? Kenneth Offit, Chief of the Clinical Genetics Service at Memorial Sloan Kettering Cancer Center, says that people can engage in a variety of cancer-prevention strategies, depending on their individual cancer risk and personal preferences. Adopting dietary and lifestyle changes and regular screening with proven methods such as colonoscopy may be helpful for some people. Others may opt for more-aggressive prevention strategies such as breast surgery. Doctors at Memorial Sloan Kettering can help patients understand the true risk represented by a positive finding on a genetic test, and the benefits and risks of each approach to preventing cancer.
