From my understanding Pat G. was very sick even last summer during the Silent Lambs march where she made an unproven allegation of abuse against a prominent known individual, likely knowing her health would never allow her to take it to court to prove it. I think it very important not to turn an allegation into a fact (not saying anyone has done so yet), since no proof has or it seems ever will be provided in support of the claim.
I am very sorry to hear that her health has gotten worse. After being through so much in her life to this point, having to now deal with cancer just isn't fair. She seems like a fighter and hope she rises up and fights against this as well.
