What are abnormal B cells?
When you have B-cell lymphoma, your body makes too many abnormal B cells. These cells can’t fight infections well. They can also spread to other parts of your body. There are two types of lymphoma: Hodgkin’s lymphoma and non-Hodgkin’s lymphoma. Most B-cell lymphomas are non-Hodgkin’s lymphoma.
What do B cells do in the immune system?
B cells create antibodies. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection. B cells can also recruit other cells to help destroy an infected cell.
