 A couple of sources I can think of, the American Cancer Society does a lovely job of distilling the most current information into a way that regular people can read and use, and then also providing all the background. So if you go in there, you find the basics, you find what you need, great. And if you want to drill down and understand more details, you can get it from there as well. There's an organization called FORCE, which is the largest national nonprofit that is attempting to serve the needs of people at high risk of breast and ovarian cancer. And they also have a wealth of information about risk.
