Possibly that approach has contributed to so much of the abuse, they didn't ask enough questions. It was often extremely easy to obtain DAS.
By someone getting approved just saying they have cancer, that doesn't necessarily make them eligible based on the need. For example, my FIL has skin cancer on his chest. If all he said was that he had cancer, should he automatically be eligible?
Not trying to minimize the seriousness of cancer by any means, I'm just saying that extremely broad and overall diagnoses, even saying autism, or cancer, or heart issues, should not automatically make someone eligible for receipt.
