Final answer:
Lymphoma is cancer that affects lymphocytes in the lymphatic system. It primarily involves malignant T and/or B lymphocytes. There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma, with various subtypes.
Step-by-step explanation:
Among the given options, the statement that is true of lymphoma is C. Lymphoma is cancer of lymphocytes. Lymphoma is a type of cancer that affects the lymphatic system, specifically lymphocytes, which are a type of white blood cell (WBC). There are different types of lymphocytes involved in the lymphatic system, including B and T cells, which are part of the adaptive immune system. Different types of lymphoma affect these lymphocytes in various ways.
Lymphocytes are responsible for fighting infections, and when they become malignant, they can collect in the lymph nodes, spleen, liver, and other tissues. This can lead to immune system dysfunction and leave the patient vulnerable to infection. The two major categories of lymphoma are Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL), with NHL having many more subtypes, each depending on specific lymphocyte involvement.
