multiple myeloma
Let an agent explain multiple myeloma in general terms, relay biology, stages, symptoms, treatment approaches and research from haematology and cancer charity sources, route urgent symptoms and point to specialist care and support, describe the named forms, and distinguish myeloma from MGUS, lymphoma, leukaemia and bone metastases, without diagnosing individuals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain multiple myeloma in general terms, relay biology, stages, symptoms, treatment approaches and research from haematology and cancer charity sources, route urgent symptoms and point to specialist care and support, describe the named forms, and distinguish myeloma from MGUS, lymphoma, leukaemia and bone metastases, without diagnosing individuals.
A cancer of plasma cells in the bone marrow that produce abnormal antibodies, called M proteins, causing bone lesions and fractures, anaemia, kidney damage including myeloma kidney, high calcium and infections, preceded by monoclonal gammopathy of undetermined significance and smouldering or indolent myeloma, which may be monitored before treatment, with variants the registry aliases name such as non-secretory myeloma and refractory disease, and the related plasma cell disorder POEMS syndrome; treatments include proteasome inhibitors, immunomodulatory drugs, monoclonal antibodies, stem cell transplantation and CAR-T and bispecific antibody therapies, and outcomes have improved though it is usually not curable. Care is led by haematology teams, and severe bone pain, confusion, reduced urination or signs of infection need urgent medical care.
What it is for: Not applicable; a blood cancer.
It can be explain biology and stages; relay treatment approaches in general terms; describe named forms; route urgent symptoms and point to support.
Distinguishing features
Plasma cell clone
M protein
Bone and kidney damage
Rapidly evolving treatments
What it looks like
Not visible externally; seen in blood tests, bone marrow samples and bone imaging.
Physical character
CRAB features: calcium, renal, anaemia, bone note
IMWG diagnostic criteria updated: 2014 year
first BCMA CAR-T approval: 2021 year - US FDA
How it is recognised
Plasma cell cancer of the bone marrow
Smouldering myeloma, refractory plasma cell neoplasm, non-secretory myeloma, POEMS syndrome, myeloma kidney, indolent myeloma
MGUS is a precursor; lymphoma affects lymphocytes; leukaemia affects blood-forming cells broadly; bone metastases come from other cancers
