Scientists have also discovered the next defective gene to contribute to an increase in breast cancer susceptibility, which they naturally called BRCA-2. The incidence of BRCA-2 appears to be slightly less than BRCA-1. BRCA-2 is autosomal dominant also and resides on the thirteenth chromosome. Initially, it was believed that the presence of the BRCA-2 gene defect did not appear to increase risk for ovarian cancer. (more…)

All cancer is genetic. That is to say, that in order for a normal cell to convert to a cancerous cell, a genetic mishap must occur. These genetic mishaps, or mutations, occur quite frequently and are usually of little consequence unless the event occurs at a critical location on one of the chromosomes. A single mutation does not lead to a cancer. Cancer results from two to three separate events over time. (more…)
