The short answer
Not every plasma cell problem is treated. A published checklist separates MGUS and smoldering myeloma from active disease, using calcium, creatinine, hemoglobin, bone lesions, marrow plasma cells and the free light chain measurements.
Active disease is marked by set findings: calcium more than 1 mg/dL above normal, creatinine over 2 mg/dL, hemoglobin under 10.0 g/dL, bone lesions, 60 percent or more marrow plasma cells, or a free light chain ratio of 100 or more with the involved light chain at 100 mg/L or above.
Serum albumin and beta-2-microglobulin are both named as independent markers of outlook, so ask for the numbers rather than the summary.
If a skeletal survey shows nothing, whole-body scanning and MRI of the spine and pelvis perform about equally in finding bone lesions.
Whether to have an autologous transplant is a separate question from when stem cells are collected; cells can be collected now even if the transplant waits.

The full explanation.
Do you need treatment yet?
Not every plasma cell problem is treated. NCI separates MGUS, then smoldering myeloma, then active myeloma that needs treatment. MGUS usually causes no symptoms and is watched rather than treated, but it is not nothing: a small risk of progressing to myeloma continues for life, and it is occasionally linked to kidney, nerve or bone problems of its own. That is why it comes with a follow-up schedule instead of a discharge.
The line between them is drawn by a published checklist. NCI lists the findings that mean active disease. Calcium more than 1 mg/dL above the normal range. Creatinine over 2 mg/dL, or creatinine clearance under 40. Anemia with hemoglobin under 10.0 g/dL. One or more bone lesions on imaging. Plasma cells at 60 percent or more in the marrow. A free light chain ratio of 100 or more, provided the involved light chain itself measures at least 100 mg/L. More than one focal spot of at least 5 mm on scanning.
Ask which of those apply to you. If none do, ask what the plan for watching looks like.
The tests that set the plan
NCI lists what is measured at diagnosis. Serum albumin and beta-2-microglobulin are both named as independent markers of outlook.
Imaging matters too. If a skeletal survey shows nothing, NCI describes whole-body scanning or MRI of the spine and pelvis, and says the two perform about equally in finding bone lesions.
If amyloid is suspected, NCI describes a fat pad needle sample and staining the marrow biopsy as the easiest and safest confirmation.
Ask for your numbers, not just the summary. They become the baseline everything later is compared against.
Chromosome testing on the marrow
NCI's summary covers FISH and other chromosome studies on the bone marrow sample. These help sort risk and can shape drug choice.
Ask what your marrow showed, in plain words. Ask what it means for the plan rather than for the statistics.
Transplant, and when stem cells are collected
Autologous stem cell transplant means your own cells are collected, then given back after high-dose treatment. NCI covers it in depth for people fit enough.
The timing question is separate from the doing question. Ask whether cells should be collected now even if the transplant itself waits.
Choosing the first drug combination
NCI describes combinations built around bortezomib and lenalidomide, with daratumumab added. It cites trials testing exactly that addition in newly diagnosed disease.
Ask whether you are getting three drugs or four, and why that choice for you.
Bones and kidneys need attention now
Myeloma can damage kidneys through high calcium, amyloid or light chains. NCI names all three routes.
Bones weakened by myeloma may need treatment before anything else starts. Ask whether any of yours is at risk of breaking.
Questions for the myeloma visit
- Do I have active myeloma, or something we watch?
- Which of the active-disease findings do I have?
- What did my marrow biopsy and chromosome tests show?
- What are my albumin and beta-2-microglobulin?
- Am I a transplant candidate, and should cells be collected now?
- Will my first treatment be three drugs or four?
- Do any of my bones need treating before we start?
When to get help sooner
Myeloma affects bone, kidneys and blood counts, so a few symptoms need action faster than a routine call.
- Call 911 or go to an emergency department if you develop new weakness or numbness in both legs, a band of pain around your chest or back, or new trouble controlling your bladder or bowels. That combination can mean pressure on the spinal cord, and hours matter. Go straight to emergency care as well for sudden severe back pain after a minor movement, heavy bleeding, or sudden breathlessness or chest pain.
- Call your myeloma team at once, day or night, if you have a temperature of 100.4 °F (38 °C) or higher while receiving chemotherapy, and go to an emergency department if you cannot reach them quickly. The CDC describes fever during chemotherapy as a medical emergency, not something to leave on an answering machine.
- Call your care team the same day if you feel unusually confused, drowsy, thirsty or nauseated, or you are passing much less urine. These can point to a high calcium level or failing kidneys.
- Call your care team within a day or two if bone pain is steadily building, you are newly short of breath on stairs, or infections keep coming back.

Common questions
Do I need treatment right away?
Not always. MGUS and smoldering myeloma are watched rather than treated, though watching is lifelong because the risk of progression never quite goes away. Ask which of the active-disease findings apply to you, and if none do, ask what the watching plan looks like and how often.
What does the marrow biopsy add?
It gives the plasma cell percentage plus FISH and other chromosome studies. Those help sort risk and can shape drug choice. Ask what yours showed in plain words.
Could my kidneys or bones need attention before treatment starts?
Yes. Myeloma can damage kidneys through high calcium, amyloid or light chains, and weakened bones may need treating first. Ask whether any of yours is at risk of breaking.
Which symptoms cannot wait?
New weakness or numbness in both legs, a band of pain around the chest or back, or new trouble controlling bladder or bowels mean calling 911, because hours matter. A temperature of 100.4 °F or higher during chemotherapy is also an emergency.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
