Genetic Screening in Buffalo

With increased application of BRCA testing and genomic-based healthcare, it is the goal of this program to ensure adequate preparation of patients for decision making regarding hereditary cancer risk and genetic testing, potential health issues, cancer screening, and risk reduction options.

The Hereditary Cancer Risk Assessment Program is based on personal and family history and BRCA genetic testing.

Our genetic screening program benefits the current and future patients of CCS with a new program concentrating on hereditary cancer risk assessment, genetic testing, and screening plans based on individual risk levels.
