C94: Other leukaemias of specified cell type

The group of conditions under the title "Other Leukaemias of Specified Cell Type" refers to specific types of blood cell cancer that do not fall into the categories of lymphoid, myeloid, or monocytic leukaemia. These leukaemias originate from abnormal growth of certain types of blood cells in the bone marrow, leading to an abnormal overproduction of these cells. The exact cell type affected varies, which influences symptoms, disease progression, and potential treatment strategies. Common symptoms across this group of conditions might include fatigue, easily bruised skin, unexplained weight loss, night sweats, and frequent infections due to a disrupted immune system. However, it's important to note that symptoms can also differ significantly depending on the specific type of cell affected by the leukaemia. Like other forms of cancer, these diseases can develop due to a combination of genetic and environmental risk factors, though the exact causes remain unclear for many types.
