Why is "Sporadic bovine lymphosarcoma" trending?

Wikipedia Overview

Sporadic bovine lymphosarcoma (SBL) is a rare type of cancer seen in cattle, characterized by the overgrowth of lymphoid tissue. It was first described in 1871 in Lithuania in a cow suffering from lymph node hypertrophy and splenomegaly. No specific causative agent has yet been discovered, as the disease appears to occur sporadically in cattle population, as the name suggests. This condition can manifest itself in three different forms: juvenile form, thymic form and skin. Although very similar in pathology to enzootic bovine leukosis, sporadic bovine lymphosarcoma is not related to infection from the retrovirus bovine leukemia virus (BLV). Bovine leukosis caused by bovine leukemia virus occurs frequently in adult cattle population, whereas sporadic bovine leukosis appears to affect only younger cattle. All forms of SBL are rare and are typically seen in cattle less than 2 years of age. Most commonly, B-cell lymphomas are seen as a result of bovine leukemia virus infection whereas tumor cells of sporadic lymphomas are all immature lineage of T-cells and less commonly B-cells. Previous findings have shown that the proto-oncogene C-Myb is expressed in most sporadic lymphomas but not in enzootic leukosis. These alterations to small sets of cellular genes appear to contribute significantly to the neoplastic transformation of cells, notably leukocytes and lymphocytes in this disease. All forms of sporadic bovine lymphosarcoma may have varying clinical presentation related to the affected organs.
