Multiple Myeloma is a form of blood cancer that affects plasma cells, which are responsible for producing antibodies. In this condition, plasma cells become cancerous and multiply uncontrollably in the bone marrow. This leads to a range of serious health problems such as anemia, bone pain or fractures, kidney damage, high calcium levels, and frequent infections due to a weakened immune system.
While multiple myeloma is a chronic and incurable condition, it is highly treatable with modern medical advancements. Treatment typically involves induction chemotherapy, autologous stem cell transplant (ASCT), maintenance therapy, and in some cases, targeted therapy or immunotherapy.
Multiple myeloma is a type of blood cancer that affects plasma cells, a kind of white blood cell found in bone marrow. These abnormal cells accumulate and crowd out healthy blood cells, leading to anaemia, bone lesions, kidney damage, and immune suppression.
Treatment for multiple myeloma is not usually curative, but it aims to control the disease, improve quality of life, and extend survival.
Multiple myeloma is not a single uniform disease — it includes several subtypes, classified based on the type of abnormal immunoglobulin (M-protein) produced, the clinical behaviour, and genetic variations. Understanding these types helps guide treatment and predict prognosis.
This is the most common classification and is determined by the type of antibody (immunoglobulin) secreted by malignant plasma cells.
Type | Description | Prevalence |
---|---|---|
IgG Myeloma | Plasma cells produce abnormal IgG antibodies | ~50% of cases |
IgA Myeloma | Produces abnormal IgA antibodies; often involves lymph nodes and soft tissues | ~20% of cases |
IgD Myeloma | Rare, more aggressive, often with kidney and bone complications | <2% of cases |
IgE Myeloma | Extremely rare | <0.1% |
Light Chain Myeloma (Bence Jones Myeloma) | Only light chains (kappa or lambda) are produced, not full antibodies | ~15–20% of cases |
Non-secretory Myeloma | No detectable M-protein in blood or urine | ~1–5% of cases |
Type | Features |
---|---|
Smoldering Multiple Myeloma (SMM) | Early-stage, no symptoms, but risk of progression to active myeloma |
Active Multiple Myeloma | Symptomatic with CRAB features: Calcium elevation, Renal failure, Anemia, Bone lesions |
Relapsed/Refractory Myeloma | Returns after treatment or stops responding to therapy |
Certain chromosomal abnormalities can affect prognosis:
Risk Group | Common Genetic Abnormalities |
---|---|
Standard Risk | t(11;14), hyperdiploidy |
High Risk | del(17p), t(4;14), t(14;16), gain(1q), del(1p) |
Patients with high-risk cytogenetics may have a more aggressive disease course and may require more intensive treatment.
Classification Basis | Examples | Notes |
---|---|---|
Immunoglobulin Type | IgG, IgA, IgD, Light Chain | Guides diagnosis and lab monitoring |
Disease Activity | Smoldering, Active, Relapsed/Refractory | Determines treatment urgency |
Genetic Risk | High-risk vs. Standard-risk mutations | Affects prognosis and therapy selection |
Secretion Behavior | Secretory vs. Non-secretory | Impacts diagnostic testing (SPEP/UPEP/FLC) |

Multiple Myeloma is a type of blood cancer that originates in the plasma cells, a type of white blood cell found in the bone marrow. In this disease, abnormal plasma cells multiply uncontrollably, crowding out healthy cells and producing abnormal proteins that can damage organs like the kidneys and bones.
The exact cause of multiple myeloma is unknown, but researchers have identified several risk factors and contributing mechanisms that may lead to its development.
These changes affect cell cycle control, allowing plasma cells to grow abnormally and resist death.
Most cases of multiple myeloma begin as a precancerous condition:
MGUS (Monoclonal Gammopathy of Undetermined Significance):
A non-cancerous condition where abnormal proteins (M-proteins) are present in the blood.
➤ 1% of MGUS cases progress to myeloma per year.
Smoldering (asymptomatic) myeloma:
A more advanced form of MGUS with higher M-protein levels and abnormal plasma cells, but no symptoms yet.
Though not definitive causes, specific exposures may increase the risk:
Age is the most significant risk factor.
Most patients are diagnosed after age 60.
Men are slightly more likely to develop multiple myeloma than women.
Risk Factor | Role in Myeloma Development |
---|---|
Genetic mutations | Directly alter plasma cell behaviour |
MGUS or Smoldering Myeloma | Precursor stages to multiple myeloma |
Radiation or chemical exposure | Potential DNA damage to bone marrow cells |
Older age | Higher cumulative genetic risk |
Male gender | Slightly increased susceptibility |
Family history | Genetic predisposition |
African descent | Statistically higher incidence |

Multiple myeloma is a chronic, relapsing-remitting cancer. Although it is not curable, it can be controlled for long periods with the right combination of treatments. Recovery focuses on achieving remission, preventing relapse, and maintaining quality of life.
Patients typically start with 4–6 cycles of induction chemotherapy (e.g., bortezomib + lenalidomide + dexamethasone).
Eligible patients undergo autologous stem cell transplant after induction.
After transplant or successful chemotherapy, patients often begin maintenance therapy (e.g., lenalidomide).
Even after remission, patients require lifelong follow-up, as relapse is common.
Monitoring Component | Frequency |
---|---|
Blood tests (CBC, M-protein) | Every 1–3 months |
Bone marrow biopsy (if needed) | At relapse or major milestones |
Imaging (PET-CT/MRI) | As clinically indicated |
Supportive care reviews | Every 3–6 months |
Patients may receive targeted therapies, such as daratumumab, carfilzomib, or pomalidomide.
Test | Frequency |
---|---|
CBC, Creatinine, Calcium | Monthly |
M-protein levels (SPEP/UPEP) | Every 1–3 months |
Free light chain assay | Every 1–3 months |
Bone marrow biopsy | At diagnosis & relapse |
Imaging (PET-CT or MRI) | As needed for symptoms |
Recovery in multiple myeloma doesn’t mean “cured,” but achieving a deep and sustained remission, minimizing symptoms, and maintaining a high quality of life over the long term.
