Well two accomodations: 1) I have not studied Endocronology nor Nuclear Medicine, 2) I cannot backup the rumour mill having not viewed the studies nor those accused of covering up a possible cure.
I had read sometime ago that there is a possible cure theory. The treatment in question or rather the drug has FDA approval is cost effective and on the market. So, and I am over simplifiying and possibly ommitting details but as I understand this is a drug or a hormone that tells the immune system that what the body is producing (insulin) is not a pathogen and harmless so that the pancreas can continue insulin production. I am trying to watch what I say but a certain familiar organization has tried to hamper the study in regards to a cure in existence. And again rumor has it that a certain company (can't back this up) involved in diabetes care has purchased I don't know like licensing rights? to this drug.
I am fortunate to have insurance and my copays for doctor visits and prescriptions are minimal, but it seems that I am in the minority having a preexisting condition and still having insurance coverage for a terminal disease, and I do believe that companies and doctors do profit over the existance of said disease as a major source of income. But in closing I do pray for life.
