Is detecting BC classified as a pre-existing condition?

@Wonk I first came here with a multitude of questions which were always answered, and then in a remarkably short time, someone came on with a question that I was able to answer. At a time when I felt so useless it felt so good to help someone else. We pay it forward to thank the wonderful folk who helped us at the beginning, and all the way through. I still have questions!
