Chronic myelomonocytic leukemia ( CMML) is a type of leukemia, which are cancers of the blood-forming cells of the bone marrow. In adults, blood cells are formed in the bone marrow, by a process that is known as haematopoiesis. In CMML, there are increased numbers of monocytes and immature blood cells ( blasts) in the peripheral blood and bone ...
Micrograph of an anaplastic large-cell lymphoma. H&E stain. Anaplastic large-cell lymphoma ( ALCL) refers to a group of non-Hodgkin lymphomas in which aberrant T cells proliferate uncontrollably. Considered as a single entity, ALCL is the most common type of peripheral lymphoma [1] and represents ~10% of all peripheral lymphomas in children. [2]
A circulating tumor cell ( CTC) is a cell that has shed into the vasculature or lymphatics [1] from a primary tumor and is carried around the body in the blood circulation. CTCs can extravasate and become seeds for the subsequent growth of additional tumors ( metastases) in distant organs, a mechanism that is responsible for the vast majority ...
Deaths. 111,000 (2015) [10] Acute lymphoblastic leukemia ( ALL) is a cancer of the lymphoid line of blood cells characterized by the development of large numbers of immature lymphocytes. [1] Symptoms may include feeling tired, pale skin color, fever, easy bleeding or bruising, enlarged lymph nodes, or bone pain. [1]
Cancer is the leading cause of death in dogs. [1] It is estimated that 1 in 3 domestic dogs will develop cancer, which is the same incidence of cancer among humans. [2] Dogs can develop a variety of cancers and most are very similar to those found in humans. Dogs can develop carcinomas of epithelial cells and organs, sarcomas of connective ...
