How are you feeling? I am so sorry that you are going through this? Do you have short and/or long term disability at work? Do you know about FEMLA? Check it out, if you are unable to work, your job is protected.
That is where your employer made need to know why you are on leave (if it comes to that). Otherwise, I would wait...the last thing you need is to deal with a lot of extra stress at work with gossip etc going around. I would not tell a soul, if I wanted to keep it secret... even people you trust, because sometimes they can't keep their mouths shut.
Good luck to you and here's wishing you a speedy recovery!
