What happens if multiple myeloma is not treated?

Short answer
If multiple myeloma is not treated, abnormal plasma cells may build up, weaken bones, reduce healthy blood cells, and affect kidney function.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

Possible effects on the body
Multiple myeloma is a cancer of plasma cells in the bone marrow. Active disease can crowd out cells that make red blood cells, white blood cells, and platelets. This may lead to Persistent Fatigue, infections, or bruising and bleeding more easily.
Myeloma can also damage bone structure, causing Persistent Bone Pain, fractures, or high calcium levels. Abnormal proteins may strain the kidneys. Spinal Cord Compression is an emergency complication if disease or a collapsed bone presses on the spinal cord.
What to do after diagnosis
Arrange review with a myeloma specialist and ask which blood, urine, imaging, and bone-marrow tests are needed. Smouldering Myeloma is different from active myeloma and may be monitored in selected situations, so the distinction matters.
Treatment may combine medicines with Bone-Strengthening Therapy, Radiotherapy for a painful focal area, Autologous Stem Cell Transplant, or CAR T-Cell Therapy. The choice depends on disease features, fitness, prior treatment, and preferences.
When to seek urgent care
Seek emergency help for new leg weakness, numbness, loss of bladder or bowel control, sudden severe back pain, confusion, or inability to stand. Contact the team promptly for fever, new infection symptoms, a suspected fracture, or much less urine than usual.
Questions for your doctor
Is my disease active or smouldering? Are my bones, kidneys, or blood counts affected? What symptoms could signal spinal cord compression? Which treatment is recommended first, and how will response and side effects be monitored?
Questions people ask
Can untreated myeloma cause bone problems?
Yes. Active myeloma can weaken bones and cause pain, fractures, or pressure on the spinal cord.
Is smouldering myeloma the same as active myeloma?
No. Smouldering myeloma has different features and may be monitored in selected people, while active disease may need treatment.
