On June 1, 2017 Sean was diagnosed with Acute Promyelocytic Leukemia (APL) at Shady Grove Medical Center in Rockville, Maryland. He was transported to Johns Hopkins in Baltimore, Maryland later that afternoon to begin immediate care. On June 3 the molecular pathology report confirmed he did in fact have APL - a cancer of the blood cells, specifically of the white blood cells. It is considered a rare type of leukemia, however it has the highest success rate of the other types. On average, 1 case a month comes through Johns Hopkins. Sean was approached to be a part of a clinical research study, and of course being the analytical scientist that he is, he has agreed to Dr Ghiaur's request.
Johns Hopkins specializes in Leukemia care and is one of the top cancer hospitals in the US. The two Oncologists that will be overseeing his care are Drs. Amy Dezern and Gabriel Ghiaur.
