Costs and benefits of diagnosing familial breast cancer

Molecular screening for breast cancer prevention, early detection, and treatment planning: combining biomarkers from DNA, RNA, and protein

The completion of the human genome project, along with the ancillary technologies derived from this effort, provides the ability to comprehensively analyze patient tumors as well as the individual patient's own genetic make-up at the DNA, RNA, and protein level. As a result, novel molecular screening techniques have the potential to push the boundaries of detection to even smaller tumors and also to allow accurate risk assessment, cancer prevention, and treatment planning in individual women. This review focuses on advances over the past 2 years in the use of molecular signatures and circulating tumor cells for early breast cancer detection and for prediction of response to therapy.

How to establish a high-risk cancer genetics clinic: Limitations and successes

The development of technology to locate and isolate cancer susceptibility genes has brought together the fields of oncology, cancer control, genetics, and genetic counseling to create a new specialty of cancer risk counseling with the goal to communicate more accurate information about personal cancer risk profiles based on personal and family histories. As cancer risk assessment and counseling services become standard of care in medical practice, their availability is increasingly moving from comprehensive cancer centers and academic institutions to community settings. High-risk cancer genetics clinics in the community face several challenges, including staffing, time commitment, costs, and unique quality control issues. The societal benefits include a more educated public armed with the information needed to make health decisions appropriate for the individual level of risk.
