Denver Aud, a Bedford firefighter, got a nasty surprise late last year when a sore throat sent him to a doctor.
A blood test done as part of the exam indicated some abnormalities, and this led to a bone marrow biopsy and cancer screening. The cancer screening led to a diagnosis of myelodysplastic syndrome (MDS).
MDS is a type of cancer that affects the stem cells that produce blood cells. Aud said his MDS would eventually destroy his immune system if left untreated.
