Consider genetic counseling and testing
Increasingly, scientists are identifying altered genes that put people at high risk of developing certain cancers. It is estimated that 5 to 10 percent of all cancers may be hereditary. Researchers can now test people to see if they carry any of these altered genes. For example, testing is available for hereditary forms of breast and colon cancers.
People with a strong family history of cancer--two or more close relatives with breast, ovarian, or colon cancer-- should consider genetic counseling. A counselor will explore with you issues related to testing, such as how one’s family might react or how results of a genetic test might affect your ability to get insurance. Based on your level of risk, a genetic counselor can also develop a risk management plan, which may include taking medications to reduce your risk (chemoprevention) or undergoing risk-reducing surgery, such as prophylactic mastectomy. Strategies for cancer screening and recommendations for a healthy lifestyle also will be reviewed.
