Wow I never even thought of Maddy having cancer. I`ve read that some women have a positive pregnancy test, and they assume they`re pregnant when it turns out to be cancer. I`ve seen it happen before, but I can`t remember what show it was.
I suppose it makes sense. When Maddy first came into H&A with Spencer as teen runaways, Maddy got sick and was hospitalised for a while. It`s possible that whatever sickness Maddy had - it manifested itself into cancer cells. That would explain Maddy passing out last week on the Aus pace H&A.
Of course I could be completely wrong - it`s just guess work at this stage.
