Myelodysplastic syndromes—sometimes shortened to “MDS” or called “myelodysplastic neoplasms”—are a family of blood-forming stem-cell cancers that start inside the soft marrow space of our bones. In MDS the genetic instructions that tell a stem cell how to mature become damaged. As a result, the marrow cranks out misshapen or immature blood cells that die early or never leave the marrow. Over time most people with MDS don’t have enough healthy red cells, white cells, or platelets in their bloodstream (a state doctors call “cytopenia”). The low counts lead to tiredness, infections, easy bruising, and a small but serious risk of transforming into acute myeloid leukemia (AML) if the faulty clone keeps picking up extra mutations. NCBIASH Publications
Even though some forms behave slowly for years, the key feature that classifies MDS as a malignancy is the presence of a genetically abnormal (clonal) stem-cell population that grows on its own. That clone competes with normal stem cells and eventually crowds them out. Because every patient’s clone carries a different set of DNA typos, MDS shows an enormous variety in how fast it worsens and whether it ever turns into AML. NatureAmerican Cancer Society
Major clinicopathologic types you’ll hear about
International experts recently updated the World Health Organization (WHO/ICC 2022) categories. Each label describes what the bone-marrow lab sees under the microscope, how many cell lines look distorted (dysplastic), how many immature “blast” cells are present, and whether a high-risk chromosome change is driving the disease.
MDS with single-lineage dysplasia (MDS-SLD) – Only one blood-cell family (red cells or white cells or platelets) looks abnormal. Counts are often mildly low and these cases progress slowly.
MDS with multilineage dysplasia (MDS-MLD) – At least two blood-cell families show dysplasia; cytopenias are broader and the outlook is a bit worse.
MDS with ring sideroblasts (MDS-RS) – Cells meant to become red cells trap iron in rings around their nuclei. The body can’t recycle that iron well, so anemia dominates.
MDS with isolated del(5q) – Patients lose a slice of chromosome 5; they often respond dramatically to the drug lenalidomide.
MDS with excess blasts-1 (MDS-EB-1) – 5 %–9 % blasts in marrow (or 2 %–4 % in blood). Blasts are immature precursors; the higher the percentage, the closer the condition creeps toward leukemia.
MDS with excess blasts-2 (MDS-EB-2) – 10 %–19 % blasts in marrow (or 5 %–19 % in blood). The leukemia risk is much higher.
Hypoplastic MDS – Marrow is paradoxically “empty” (few cells) but the ones left are abnormal; symptoms mimic aplastic anemia.
MDS-unclassifiable (MDS-U) – Rare cases that don’t fit the boxes above but clearly carry a clonal genetic lesion and cytopenias. PMC
Main causes and risk factors
MDS usually strikes adults over 60 and often seems to appear “out of the blue,” yet researchers have pinned down a long list of triggers that can injure marrow DNA:
Natural aging – The older a stem cell, the more random mutations it collects.
Previous chemotherapy (alkylating agents, platinum drugs, topoisomerase II inhibitors) – These lifesaving drugs can scar DNA years later. American Cancer Society
Radiation therapy – High-energy beams that kill tumors can also harm marrow DNA. American Cancer Society
Occupational or environmental benzene exposure – A solvent used in oil, rubber, and some cleaning products. American Cancer Society
Cigarette smoking – Tobacco smoke contains benzene and other DNA-damaging chemicals. American Cancer Society
Petroleum-based pesticides and herbicides – Long-term exposure elevates risk.
Chronic heavy-metal exposure (lead, mercury) – Metals generate free radicals that nick DNA.
Inherited bone-marrow failure syndromes (Fanconi anemia, Diamond-Blackfan anemia) – Genes that normally repair DNA are faulty from birth.
Shwachman–Diamond and other congenital neutropenia syndromes – Chronic marrow stress drives mutations that culminate in MDS.
Down syndrome and other chromosome trisomies – Extra copies disrupt gene dosage.
Germline telomerase disorders (TERT, TERC mutations) – Telomere shortening in stem cells accelerates DNA breaks.
Long-term immune-suppressive therapy (e.g., for organ transplant) – Reduces immune surveillance, letting mutant clones expand.
Prior autologous or allogeneic stem-cell transplant – The intense chemo/radiation conditioning can spark a second clone years later.
Chronic inflammatory diseases (rheumatoid arthritis, ulcerative colitis) – Persistent cytokines stir up oxidative DNA damage.
Autoimmune marrow attack (e.g., paroxysmal nocturnal hemoglobinuria evolving to MDS) – Surviving “escape” clones may carry high-risk mutations.
Long-term exposure to formaldehyde and organic solvents – Similar genotoxic effect as benzene.
Severe vitamin B₁₂ or folate deficiency – Prolonged DNA-synthesis stress fosters errors.
Chronic viral infections (hepatitis C, HIV) – Ongoing immune stimulation and direct viral effects hurt marrow cells.
Obesity-associated oxidative stress – Adipokines and free radicals damage DNA repair pathways.
Random “bad luck” mutations – Even without recognized exposures, spontaneous replication errors can create a rogue clone. Wikipedia
Symptoms
Because MDS starves the body of one or more healthy blood-cell types, symptoms cluster around anemia, low platelets, or low white cells:
Deep fatigue and weakness – The hallmark of anemia. Mayo Clinic
Shortness of breath on mild exertion – Less oxygen reaches muscles. Mayo ClinicAmerican Cancer Society
Pale or sallow skin – Fewer red-cell pigments. Mayo Clinic
Rapid or pounding heartbeat (palpitations) – The heart works harder to deliver oxygen. Rare Disease Advisor
Dizziness or light-headedness – Brain gets less oxygenated blood.
Headaches – Same mechanism as dizziness.
Chest pain or tightness – In people with coronary disease, anemia can unmask angina. American Cancer Society
Easy bruising – Platelets are too few or function poorly. Mayo ClinicHealthline
Prolonged bleeding from small cuts – Low platelet count delays clotting.
Pinpoint red spots (petechiae) – Tiny skin bleeds signal severe thrombocytopenia. Mayo Clinic
Frequent or stubborn infections – White-cell shortage weakens defenses. Mayo Clinic
Fever without obvious cause – Infection or inflammatory cytokines from the clone.
Unintentional weight loss – Chronic illness burns calories. Leukaemia Foundation
Bone or joint aches – Marrow expansion and cytokine release irritate bone linings.
Night sweats – Cytokines reset the brain’s thermostat, similar to other marrow cancers. Blood Cancer UK
Diagnostic tests
Below are the studies doctors order, grouped the way you requested. Each test has a plain-language purpose statement so readers know why it matters.
Physical-examination assessments
General inspection for pallor and fatigue – Simply looking at the skin and eye-lining can hint at anemia severity.
Skin and mucous-membrane check for bruises, petechiae, or rashes – Spots alert the doctor to platelet problems.
Lymph-node palpation – Enlarged nodes might point to an unrelated lymphoma rather than MDS.
Abdominal palpation and percussion for spleen or liver size – An enlarged spleen may be a sign that it is trapping blood cells or that the clone has spread.
Manual (bedside, practitioner-performed) tests
Capillary refill and nail-bed pressure test – A rough gauge of blood-oxygen delivery.
Bleeding-time or clot-retraction test – Old-school but still used in low-resource settings to screen platelet function.
Laboratory & pathological studies
Complete blood count (CBC) with differential – Confirms cytopenias and flags abnormal shapes or sizes. American Cancer Society
Peripheral-blood smear review – A pathologist studies cell size, shape, and immature forms.
Reticulocyte count – Shows whether the marrow is trying to compensate for anemia.
Serum ferritin, iron, total iron-binding capacity – Rules out iron-deficiency mimicry.
Vitamin B₁₂ and folate levels – Low levels can copycat MDS features or worsen dysplasia. American Cancer Society
Serum erythropoietin level – Guides treatment; low levels predict good response to synthetic EPO shots.
Bone-marrow aspirate morphology – Liquid sample lets the lab count blasts and ring sideroblasts. American Cancer Society
Core bone-marrow biopsy – Solid piece shows overall cellularity and scarring. American Cancer Society
Conventional cytogenetic karyotyping – Detects chromosome deletions or duplications such as del(5q). bloodjournal.org
Fluorescence in situ hybridization (FISH) – A faster way to spot specific chromosome changes.
Next-generation sequencing (NGS) mutation panel – Looks for TP53, ASXL1, TET2, and other driver mutations that influence prognosis. bloodjournal.org
Electrodiagnostic studies
Electrocardiogram (ECG) – Severe anemia can strain the heart and cause arrhythmias, so doctors check the electrical rhythm base-line.
Holter monitor (24-hour ECG) – Captures intermittent rhythm problems triggered by low oxygen or electrolyte shifts.
Imaging examinations
Ultrasound or MRI of spleen and liver – Finds hidden enlargement or iron overload in patients who’ve had many blood transfusions. X-rays or CT scans are seldom needed but may be used to plan a marrow biopsy or look for other cancers. Cleveland ClinicAmerican Cancer Society
