It is one of a related group of blood cancers known as âmyeloproliferative neoplasms (MPNs)â in which bone marrow cells that produce the blood cells develop and function abnormally. 2  The resulting fibrous scar tissue formation leads to severe anemia, weakness, fatigue and an enlarged spleen and liver.
A doughnut or donut (both: /ËdoÊnÉt/ or /ËdoÊnÊt/; see spelling differences) is a type of fried dough confectionery or dessert food.
Irving described âballs of sweetened dough, fried in hogâs fat, and called doughnuts, or olykoeks.â[6] These ânutsâ of fried dough might now be called doughnut holes. Doughnut is the more traditional spelling, and still dominates outside the US. At present, doughnut and the shortened form donut are both pervasive in American English.
