Can myelodysplastic syndromes really turn into leukemia?
Summary
Yes. Roughly 25–30 % of people diagnosed with myelodysplastic syndromes (MDS) will develop acute myeloid leukemia (AML), usually within three to five years. The risk is higher in patients with excess blasts, certain chromosome changes, or who delay disease-modifying therapy. Close blood-count monitoring, timely treatment, and early referral to a hematologist can lower the odds of progression.
How often does MDS change into acute myeloid leukemia (AML)?
Most—but not all—patients with MDS live many years without ever developing leukemia. Whether progression happens depends on the exact MDS subtype, genetic mutations, and treatment choices. According to Sina Hartung, MMSC-BMI, “For higher-risk subtypes, nearly one in three patients will see a leukemic transformation within 36 months if no disease-modifying therapy is given.”
- One in three MDS cases progress within five yearsPopulation studies from the U.S. SEER program show a 28 % cumulative incidence of AML transformation five years after MDS diagnosis.
- Low-risk subtypes carry under 10 % riskPatients with isolated chromosome 5q deletion or ring-sideroblast MDS progress far less often, especially when treated with lenalidomide or luspatercept.
- Excess blasts triple the dangerMDS with 10–19 % blasts in bone marrow advances to AML in about 80 % of patients within two years without stem-cell transplant.
- TP53 and ASXL1 mutations accelerate progressionGenetic testing shows that these mutations shorten time to AML by roughly 12 months compared with patients without them.
- Four in ten higher-risk patients progress to AMLThe Bristol Myers Squibb fact sheet states that roughly 40 % of people classified as higher-risk MDS experience a rapid transformation into acute myeloid leukemia. (BMS)
- Up to 40 % of all MDS diagnoses eventually transformA 2023 NIH-hosted review of genomic studies estimates that 30–40 % of patients with myelodysplastic neoplasms ultimately develop AML over the course of their disease. (NIH)
Which symptoms warn that my MDS is getting worse?
Leukemic transformation rarely happens overnight. The body usually sends clear signals first. The team at Eureka Health notes, “New bruising or a sudden drop in blood counts often precede a bone-marrow blast surge.”
- Unexplained fevers lasting more than 48 hoursPersistently low neutrophils make infections common; rising fevers can mean both infection and blast expansion.
- Bruising or bleeding from minor bumpsPlatelets below 30 × 10⁹/L often appear two to four weeks before AML is diagnosed.
- Rapid fatigue not relieved by restA hemoglobin fall of >2 g/dL within a month is a red flag for marrow failure.
- Bone pain in the sternum or hipsExpanding leukemic cells raise intramedullary pressure, causing deep, aching pain.
- New night sweats drenched clothingCytokine release from proliferating blasts can drive profuse sweating even in cool rooms.
- New purple or nodular skin patchesLeukemia cutis and other MDS-linked dermatoses can mark advanced disease; more than 34% of patients who develop these lesions go on to acute myeloid leukemia. (HealthTree)
- Increasing belly fullness from an enlarged spleenUT Southwestern notes that swelling of the liver or spleen joins fatigue and infections as key indicators that MDS is accelerating. (UTSW)
When should I call my hematologist the same day?
Certain developments can’t wait until the next scheduled appointment. Sina Hartung, MMSC-BMI, advises, “Any sudden change in bleeding pattern or a temperature over 38.3 °C warrants immediate medical review because these are classic first signs of leukemic shift.”
- A platelet count below 10 × 10⁹/LSpontaneous brain or gut bleeding risk rises sharply once platelets drop into single digits.
- Absolute neutrophil count under 0.5 × 10⁹/L with feverThis combination has a 20 % one-week mortality if untreated sepsis develops.
- New or worsening shortness of breathLeukemic infiltration of lungs or severe anemia (Hb < 7 g/dL) can cause hypoxia within hours.
- Gum or nose bleeding that won’t stop after 10 minutes of pressurePersistent mucosal bleeding suggests platelet dysfunction in addition to low count.
- Recurring infections or new mouth ulcersPersistent infections or painful mouth sores are red flags for severe neutropenia and warrant same-day medical evaluation. (BMS)
- Sudden crop of bruises or pinpoint red skin spotsUnexplained purpura or petechiae suggest critical thrombocytopenia that can quickly lead to dangerous internal bleeding without prompt care. (BMS)
What daily steps lower my chance of progression?
Lifestyle cannot cure MDS, but it can help keep counts stable and infections away. The team at Eureka Health states, “Patients who stay vaccinated, avoid raw foods, and address iron overload live longer without AML.”
- Receive age-appropriate and annual vaccinesFlu and pneumococcal shots cut infection-related hospitalizations by roughly 40 % in MDS cohorts.
- Cook meat and wash produce thoroughlyNeutropenic diets reduce serious food-borne infections, a common trigger for hospitalization that can delay treatment.
- Limit alcohol to fewer than 7 drinks a weekExcess alcohol further suppresses bone marrow and can worsen cytopenias.
- Exercise 150 minutes weekly if counts allowModerate activity improves transfusion-free survival by keeping cardiovascular fitness up during anemia spells.
- Monitor iron levels if you receive frequent transfusionsSerum ferritin above 1000 ng/mL correlates with faster disease progression; chelation therapy can reverse this.
- Avoid tobacco to spare already-strained marrowKaiser Permanente’s care guide lists smoking cessation as a core self-care step because tobacco toxins further impair blood cell production and raise infection risk. (KP)
- Follow a produce-rich, low-sodium dietHealthline advises emphasizing fruits, vegetables, whole grains, and limiting processed foods to give the bone marrow steady nutrients and lower inflammation that can worsen cytopenias. (Healthline)
Which blood tests and treatments track or slow MDS progression?
Monitoring is precise. “Serial bone-marrow biopsies every 6–12 months and monthly CBCs pick up blast creep early, when treatment can still be curative,” explains Sina Hartung, MMSC-BMI.
- Complete blood count (CBC) every 4–6 weeksTrends—especially rising white cells with falling platelets—often precede symptomatic change by a month.
- Molecular mutation panel annuallyEmergence of FLT3-ITD or RUNX1 mutations signals a shift toward AML biology.
- Hypomethylating agents delay AML by 9-12 monthsAzacitidine and decitabine lower blast percentage in 40 % of patients and prolong survival.
- Allogeneic stem-cell transplant remains the only cureFive-year leukemia-free survival reaches 50 % in suitable patients under 70.
- Clinical trials offer access to targeted drugsAgents like venetoclax or magrolimab, when combined with azacitidine, show 60 % remission rates in early studies.
- Up to 40 % of higher-risk MDS converts to AMLRoughly two in five patients in higher-risk categories ultimately transform to acute myeloid leukemia, underscoring the value of tight laboratory surveillance. (BMS)
- IPSS-R uses routine CBCs and marrow blasts to guide therapyThe Revised International Prognostic Scoring System incorporates cytopenia counts, cytogenetic findings and bone-marrow blast percentage from serial tests to predict survival and determine when to introduce disease-modifying drugs.

Frequently Asked Questions
If my MDS has a normal karyotype, is my leukemia risk still high?
Yes, but it is lower—about 15 % over five years—compared with 40 % for complex karyotypes.
Does every drop in blood counts mean I’m converting to AML?
No. Counts can fluctuate due to infections or treatment effects, but a sustained decline over consecutive tests warrants a marrow check.
Can vitamins or supplements stop progression?
No supplement has proven to prevent AML transformation. High-dose antioxidants can even interfere with some treatments.
Is stem-cell transplant recommended for people over 70?
Reduced-intensity conditioning makes transplant possible up to age 75, but overall fitness and donor availability decide suitability more than age alone.
How quickly should azacitidine start working?
Responses often appear after 3–4 cycles; earlier blast rises during therapy should prompt reassessment, not immediate discontinuation.
Are weekly CBCs overkill if I feel fine?
For low-risk MDS, monthly counts usually suffice; high-risk patients just starting therapy may need weekly tests until stable.
Will losing weight or exercising cure my MDS?
Lifestyle improves quality of life and lowers infection risk but cannot cure the underlying marrow problem.
How do I prepare for a bone-marrow biopsy?
Eat a light meal, arrange a driver if sedation is used, and stop blood-thinners as advised by your doctor.
Can I travel internationally with MDS?
Yes, if your counts are stable. Carry an updated treatment summary and plan for access to transfusions if needed.
