If you're having lymphomalike symptoms, your doctor will want to know why. Your doctor is likely to ask you questions about these things.

A biopsy is a test to check for lymphoma. For it, your doctor removes a small piece of tissue or fluid from the place that may have lymphoma. Then, the tissue is checked by a pathologist. This special doctor looks at the tissue under a microscope for lymphoma cells. A biopsy is the only way to diagnose non-Hodgkin's lymphoma.

Dr. Thomas Hodgkin classified Hodgkin's lymphoma in 1832. It's also known as Hodgkin's disease. All other types of lymphatic cancers are called non-Hodgkin's lymphoma. Hodgkin's lymphoma is discussed under its own section, under specific cancers.

A B-cell lymphoma is a type of lymphoma that begins in the B cells of the lymphatic system. This is the most common type of non-Hodgkin's lymphoma. It is much more common than T cell lymphoma. A B cell or B lymphocyte is a white blood cell that makes antibodies and is an important part of the immune system. B cells come from bone marrow. By looking at the proteins on the surface of cells, a pathologist can tell which type you have. This information helps guide your treatment plan.

These types of lymphomas begin in the T cells of the lymphatic system. This is a much less common type of non-Hodgkin's lymphoma than B cell. T cells or T lymphocytes are a type of white blood cell that attacks virus-infected cells, foreign cells, and cancer cells. T cells also produce a number of substances that regulate the immune response. By looking at the proteins on the surface of cells, a pathologist can tell which type you have. This information helps guide your treatment plan.

Your doctor may request other tests to learn more about your specific type of lymphoma and to see how widespread the lymphoma is. Along with previous exams, biopsy, and blood tests, these can help your doctor know the stage and prognosis of your disease and decide about the most effective types of treatment for you. You may need one or more of these tests.

After diagnosing your lymphoma, your doctor needs to see how far the disease has spread, called its stage. Lymphoma may be in just one area, but it tends to be more widespread. That's because it can easily move through the lymphatic system. Your treatment plan and prognosis depend on the type of lymphoma you have and its stage. But the chances of curing lymphoma have more to do with the type than the stage.

With most types of lymphoma, a grading system is used to help identify how fast the cells are growing and how they might respond to treatment. Non-Hodgkin's lymphomas are categorized into low-grade and high-grade. Sometimes these may be referred to as indolent or aggressive lymphomas.
