Montana man's cancer diagnosis changed his life: 'I trusted that he was doing what was best for me'

Anthony Olson was diagnosed with myelodysplastic syndrome, a blood disorder that’s often described as pre-leukemia.

Olson dropped out of college, moved back in with his parents and began chemo regimen.

Olson endured this for nine years ; he said he trusted that he was doing what was best for him.

Court records show Weiner may have received inappropriate, harmful or unnecessary treatments.

Dr. Tom Weiner ordered two bone marrow biopsies in 2011 that showed signs of MDS , which researchers have found is commonly misdiagnosed.

Weiner shared the negative biopsy result with Anthony Olson but told him to ignore it; all it proved was that the regimen was working.

Weiner was a powerful figure within St. Peter’s and in Helena , Montana , court records show.

Dr. Weiner misdiagnosed and improperly treated Dr. John Sutter in Helena , Montana , for years .

After Weiner was gone, Olson received another biopsy, which came back negative.

Olson sued St. Peter’s for malpractice; the hospital settled and paid an undisclosed amount.
