Sorry to hear about your AN diagnosis, but welcome to this site. You can search through the forum posts to find referrences to San Diego.
One of the things to keep in mind is that the outcome of AN treatment is related to the experience of the treatment team. So be sure to find a very experienced treatment team. Find a well respected best team, which may not be the same thing as Kaiser's best. There have been other people on this forum who have worked with Kaiser about having treatment outside of Kaiser.
If you've just been diagnosed, you're probably in a bit of shock. ANs are almost always slow growing tumors, so take your time researching your options.
