Lymphomas are hematological malignancies, which are divided into non-Hodgkin lymphoma and Hodgkin lymphoma. Non hodgkin lymphoma is a lymphoma-derived malignancy that makes up about 90% of all malignant lymphoma. According to its origin, non hodgkin lymphoma is classified into B-cell non hodgkin lymphoma and T-cell non hodgkin lymphoma. The most common types are follicular lymphoma, and diffuse large B-cell lymphoma. Lymphomas are types of cancer that develops from lymphocytes, a type of white blood cell. Diagnosis is by examination of a bone marrow or lymph node biopsy. Non hodgkin lymphoma mortality has increased in recent years and has become the seventh most frequently occurring cancer.
