Assessment for Cancer Predispositions
The Familial Cancer Risk Assessment Center at Lahey Hospital & Medical Center was created to provide comprehensive risk assessment and management recommendations to individuals with significant personal and/or family histories of cancer.
It is estimated that 1 out of every 3 Americans will develop cancer sometime during their lifetime. While it is difficult to determine the exact cause of cancer in an individual, the majority of cancer is thought to be due to a combination of factors such as chance events, the aging process, or environmental exposures. About 5 to 10 percent of cancer cases are caused by a hereditary predisposition that is passed on within a family.
Inherited factors (genes) play an important role in many cancers. We know of several genes that are associated with an increased chance of developing certain types of cancer, including breast, ovarian, colon, and uterine cancer. Features that are suggestive of a hereditary predisposition to cancer include the following:
- Multiple family members affected with the same cancer (such as breast cancer) or related cancers (such as breast and ovarian cancer, or colon and uterine cancer)
- Earlier than average ages of diagnosis
- Multiple primary cancers in the same individual (such as cancer in both breasts)
- Cancer occurring in multiple generations
Counseling & Genetic Testing Services
Cancers that are most commonly associated with a hereditary predisposition include breast and ovarian cancers, colon cancer, and uterine cancer. However, individuals with other types of cancer may also wish to consult with a genetic counselor. There are rare hereditary cancer predisposition syndromes that are associated with other types of cancer, such as thyroid cancer and stomach cancer. A genetic counselor can help evaluate your personal and family history to determine if a risk assessment appointment is necessary.
