I think it depends on her current condition. Is she now in remission or is she "declining"? I went through this with both my Mom and aunt in the last two years. If she's in remission and has a good prognosis, I'd say it's okay for you to visit as long as you take precautions. If she's declining, I'd let anyone visit her. In the long run, it's not going to make a difference and I can't think of anything worse than passing away without being able to say goodbye to all your loved ones.
