There are many options not just the one that angelina jolie took. That's correct. She chose to have preventive surgery which has been conclusively shown to not only reduce the risk but convey survival benefit, as well. Surveillance, which is just a high-tech form of screening while it does not drop the risk increases the rate at which it is detected and for some medication to lower the risk. For 87%, less than 5% for her is outstanding. Let's talk about cost here. She doesn't have to worry about it, but I mean the brca test is $3,000. The reconstruction. Sometimes insurance covers that. Sometimes it doesn't. Reconstruction, there's finally good news, robin.
