Lymphoma

Hodgkin Lymphoma

Hodgkin lymphoma (Hodgkin disease) is a cancer that starts in white blood cells called lymphocytes. Lymphocytes are part of the body’s immune system.

Lymphoma of the Skin

Lymphoma is a cancer that starts in cells that are part of the body's immune system. Rare lymphomas that start in the skin are called skin lymphomas (or cutaneous lymphomas).

Non-Hodgkin Lymphoma in Adults

Non-Hodgkin lymphoma (sometimes called NHL, or just lymphoma) is a cancer that starts in cells called lymphocytes, which are part of the body’s immune system.

Non-Hodgkin Lymphoma in Children

Childhood non-Hodgkin lymphoma is not common, but it can occur. This cancer grows in the immune system's lymphocyte cells.

Waldenstrom Macroglobulinemia

Waldenstrom macroglobulinemia (WM) is a type of non-Hodgkin lymphoma (NHL). The cancer cells make large amounts of an abnormal protein called a macroglobulin.

Symptoms vary by type of lymphoma. Some cases of lymphoma aren’t discovered until a blood test is performed for another reason. But general symptoms may include:

• Easy bruising or bleeding
• Enlarged lymph nodes or lumps under the skin
• Fatigue
• Fever
• Severe or frequent infections
• Weight loss

Skin lymphomas may also have:

• Papules (small, pimple-like lesions)
• Patches (flat lesions)
• Plaques (thick, raised or lowered lesions)
• Nodules or tumors (larger lumps or bumps under the skin)

Risk factors vary by type of lymphoma, but general causes may include:

• Autoimmune diseases
• Exposure to high levels of radiation
• Exposure to certain chemicals, including benzene
• Family history
