Those are good questions. They're not really about screening, but you are 100% right.
I'm running an international study of 8,000 women with the BRCA1 mutation and collecting comprehensive information on their treatments. Dr. Simard published a paper two weeks ago in JNCI, which looked at BRCA1 and BRCA2 mutations in 2,500 women from many countries, including Canada. We are studying that. We do see that the treatments had different effects, certainly.
Nevertheless, I do believe preventing it is better than treating it. The best we can do with treatment.... My goal, as a physician working to cure breast cancer, is to get the survival rate to 90%. My goal, as a preventive physician working in screening, is to get the survival rate to 100%.
