Multiple myeloma and plasma cell leukemia: what to know

Multiple myeloma begins in plasma cells, immune cells that normally make antibodies in the bone marrow. In plasma cell leukemia, abnormal plasma cells are also found in the bloodstream. This can affect blood-cell production and may contribute to tiredness, infections, bleeding, bone pain, or kidney problems. The diagnosis is made with blood and urine tests, examination of bone marrow, and imaging chosen by the haematology team.

Arrange prompt review with a haematologist if plasma cell leukemia is suspected or has been reported. Bring current medicines, previous blood results, and a list of symptoms. Treatment is usually planned around the speed of the illness, blood counts, organ function, and fitness for intensive therapy. Options may include chemotherapy, targeted therapy, cellular treatment, or a stem-cell transplant, alongside care for infection risk, pain, bones, and kidneys.

Seek urgent medical help for fever, shaking chills, new confusion, severe weakness, unusual bleeding, breathlessness, chest pain, very little urine, or sudden severe back pain. These symptoms can signal infection, bleeding, organ strain, or a bone problem and should not wait for a routine appointment.

Ask which tests confirmed the diagnosis, how the blood and bone marrow are affected, whether treatment needs to start immediately, and how kidney, bone, and infection risks will be monitored. Ask which warning signs should prompt a same-day call.
