Unfortunately, the Countess must...

... learn about Acute Myelogenous Leukemia (AML):

"Acute myelogenous leukemia (AML) is a malignancy that arises in either granulocytes or monocytes which are white blood cells that battle infectious agents throughout the body. AML is not inherited or contagious. It develops when there is a defect in the immature cells in the bone marrow. Although the exact cause of AML is unknown, exposure to benzene, cigarettes smoking, and prior exposure to chemotherapy drugs are linked to the disease."

And here's hoping the Countess can reign at Chicora Court a while longer with the knowledge she's being forced to accumulate.
