The genus Aesculus comprises 13-19 species of woody Trees and Shrubs native to the temperate northern hemisphere (with 6 species native to North America and 7-13 species native to Eurasia). There are also several hybrids.
Lymphoma is a form of cancer that affects the immune system-specifically, it is a cancer of immune cells called lymphocytes, a type of white blood cell. There are two broad types of lymphoma and many subtypes. The two types of lymphoma are described as: Hodgkin's or non-Hodgkin's.
What Causes Non-Hodgkin Lymphoma? Researchers have found that non-Hodgkin lymphoma (NHL) is linked with a number of risk factors, but the cause of most lymphomas ais not known. This is complicated by the fact that lymphomas are actually a diverse group of cancers. Still, scientists have made a lot of progress in understanding how certain changes in DNA can cause normal lymphocytes to become lymphoma cells.
