# Acute Myeloid Leukemia
What is it
Acute myeloid leukemia (AML) is a serious blood cancer in which the bone marrow uncontrollably produces immature myeloid cells. These abnormal cells – called blast cells – multiply rapidly and crowd out healthy blood cells. This leads to shortages of normal red blood cells, white blood cells, and platelets.
The disease is called "acute" because it progresses rapidly. The bone marrow can become completely disrupted within weeks to months, which seriously threatens body functions.
AML occurs predominantly in adults, with rising incidence as people age. Younger children and adults can also be affected. The disease develops when genetic changes cause cell mutations that break normal controls on cell division.
Causes
AML develops through mutations in the DNA of bone marrow cells. These mutations weaken the natural brakes on cell multiplication, allowing immature cells to proliferate massively.
In most cases, it is unclear why these mutations occur – it happens randomly and is not caused by anything the person has done. Sometimes there are risk factors:
- **Previous chemotherapy or radiation** for another disease can increase the risk
- **Certain genetic conditions** (such as Down syndrome) are more often associated with AML
- **Smoking** is associated with a slightly higher risk
- **Certain chemicals** (very high exposure to benzene)
- **Hereditary factors**: in some families AML occurs more frequently
Most people do not develop AML because of something they have done – it is usually chance that these mutations arise.
How the disease progresses
AML typically progresses in phases:
**Diagnosis (initial stage)**
The disease is usually discovered because someone feels unwell and blood tests show abnormal values. At diagnosis, the blood usually already contains many blast cells and normal cell production is disrupted.
**Treatment phase**
This usually lasts months. The first attempt is typically intensive chemotherapy aimed at destroying leukemic cells. The goal is "complete remission": destroy as many cancer cells as possible and restore normal blood production. This comes with severe side effects because healthy cells are also damaged.
**Consolidation phase**
When remission is achieved, follow-up treatments usually follow (additional chemotherapy or stem cell transplant) to prevent the disease from returning.
**Remission or relapse**
Some patients achieve long-term remission; others see the disease return. The timing and severity of relapse vary greatly.
The exact disease courses are highly individual, also determined by the specific genetic characteristics of the cancer cells and the patient's overall health.
Symptoms by phase
**Early symptoms (before diagnosis)**
- Severe fatigue and weakness
- Pallor
- Shortness of breath, especially during exertion
- Bruising or nosebleeds without clear cause
- Frequent infections, fever
- Bone or joint pain
- Enlarged spleen or liver (detectable on examination)
- Sometimes swelling due to accumulation of blast cells (myeloid sarcoma)
**During intensive treatment**
- Severe fatigue
- Nausea and vomiting
- Oral mucositis
- Diarrhea
- Hair and nail loss
- Very low white blood cell count (major infection risk)
- Transfusion need (blood transfusions and platelets)
**In remission**
Symptoms can decrease, although fatigue often persists. Regular check-ups follow.
**With relapse**
Symptoms can return or worsen.
What it means for daily life
AML affects almost all areas of life:
**Work and activities**
Many patients cannot work during treatment. Even after remission, fatigue can limit their ability to function. Physical exertion is usually not feasible.
**Family and relationships**
The emotional burden is significant. Partners and children must adapt to hospital admissions, uncertainty, and possible grief. Conversations with loved ones can help.
**Physical wellbeing**
Infections must be strictly prevented. Many activities (teeth brushing, avoiding wounds, hygiene) become extra important. Nutrition is essential due to side effects and limited appetite.
**Mental wellbeing**
Fear, sadness, and uncertainty are normal. Psychological support or conversations with other patients can provide help.
**Financial**
Hospital costs are high; possible loss of income due to sick leave.
**Long term**
After remission, normality can gradually return, but fear of the disease often remains. Regular follow-up appointments are necessary.
Outlook
The outlook for AML is complex and depends on multiple factors:
- **Age**: younger patients tolerate intensive treatment better and generally have better remission rates
- **Genetic characteristics**: certain mutations are associated with better or worse prognosis
- **Overall health**: serious other conditions can complicate treatment
- **Response to initial treatment**: those who achieve remission quickly generally have better prospects
At population level (all ages and types combined), approximately 30–35% of patients survive at least five years (data from 2020–2024). This figure says nothing about one person – it depends on many individual factors.
For younger patients who respond well to treatment and undergo stem cell transplantation, five-year survival can approach 40–60%. For older patients who cannot tolerate intensive chemotherapy, the outlook is more cautious.
Repeated relapses generally have worse prospects, although newer treatments sometimes help.
It is important for patients to remain realistic but cautious: figures do not give the probability for one person. Much depends on how one's own body responds.
Frequently asked questions
**Is AML hereditary?**
In most cases, no. AML arises from random mutations in a single bone marrow cell that then grows uncontrollably. This can happen to anyone. Only in rare families are there hereditary genetic risks. Children of someone with AML therefore have no increased risk.
**Can AML be cured?**
AML can go into remission – meaning all detectable cancer cells disappear and the blood recovers. This happens in many patients. "Cure" for cancer usually means someone does not see the disease return for years or for life. Some people achieve this; others see the disease return. There is no guarantee.
**What is the difference between chemotherapy and stem cell transplantation?**
Chemotherapy uses toxic substances to kill cancer cells (and also damages healthy cells). Stem cell transplantation is a procedure in which stem cells are collected (from the patient themselves or a donor), then the patient receives very high doses of chemo and possibly radiation to completely shut down the sick bone marrow, after which the healthy stem cells are returned to make new blood. It is much more invasive but can give better long-term results.
**How long does treatment take?**
Intensive induction chemotherapy usually lasts 1–2 months. Consolidation treatments follow and can continue for months. Some patients receive stem cell transplantation, which means additional weeks of hospital admission. This is followed by years of regular check-ups. The total time from diagnosis to possible long-term remission can be 6–12 months or longer.
