Bridal shower help?

Hi everyone!

I’m starting to gear up planning for my destination wedding in April of next year. When my FH and I got engaged last summer, my FH’s aunt immediately told me she wants to host my bridal shower when that time comes, as we are very close with his aunt and uncle. Since then, she has been diagnosed with a brain tumor. She is handling treatment really well and is doing great, but obviously it takes a toll. We haven’t talked about my bridal shower at all since it was originally brought up and now I do not know how to mention it again once it gets closer. I obviously do not want her to have to take on the burden of hosting if she is not up for it (definitely now with different circumstances), but I also do not want to take it away from her if she still wants to host!

My question is, how do I approach this when the wedding gets closer? I don’t want to make her feel bad, but I also want to express that she is under no pressure to still host the shower! There are a ton of people who will also step up and help, but I just don’t want her to feel uncomfortable or embarrassed.
Help!
