Is Mother Dying? Is She Lying About It?

The damndest thing, I got two voicemails yesterday/Monday that were left for Mother.  It's from the same phone number -- a cancer center, where they were talking about schedule surgery.  Surgery??  Cancer?!?!

OK, I try to avoid talking to Mother as often as I can; hell, there's an insurance bill that came yesterday/Monday that I haven't told her about yet.  I am keeping that a secret because I was hoping that me just texting her that I received these two VMs would be enough for her to take it from there.  But no, she calls me.  She asks me to text her the voicemails, which I had no idea you could do, but I did.  She said she would listen to the VMs and then get back to me.

And she did get call me back ... and supposedly after listening to the voicemails, Mother said not to worry about it, they dialed the wrong phone number.  On the one hand, phew!  On the other hand, I call shenanigans.  How much time do you need to determine a VM -- left for me, by the way, and not her -- that is scheduling surgery is BS?  Wouldn't having surgery be something foremost in your head, so that if you get information that the place you're having said surgery is looking for you, you would immediately go, "Oh!  What's their number??  I need to get in touch with them ... and oh, by the way, I have cancer!"

Well, Mother didn't do that.  So ... is she lying?  Does she really have ... cancer?
