B-cell lymphoma are types of lymphoma affecting B cells, a type of white blood cell that makes antibodies. Symptoms may include swollen lymph nodes, abdominal pain, tiredness, fever, night sweats, or weight loss. They generally start within lymph nodes, the spleen, bone marrow, or blood.

Risk factors include certain genetic conditions, environmental factors, viral infections, connective tissue disorders, and poor immune function. They are a type of blood cancer. Subtypes include Hodgkin and over 40 types of non-Hodgkin lymphoma. They are divided into slow-growing (indolent) and aggressive lymphomas. Diagnosis is by tissue biopsy.

Slow growing lymphomas often respond well to treatment, have a survival of many years, but are not generally curable. Aggressive lymphomas on the other hand many be curable but are rapidly fatal when this is not achieved. Treatments may include radiation therapy, chemotherapy, immunotherapy, or stem cell transplant.

In Western countries, B-cell lymphoma affect about 19 per 100,000 people a year and represent about 95% of lymphoma cases. About 80% of non-Hodgkin lymphomas are B-cell lymphomas. While more common in older people, certain types may occur in children.
