Acute myeloid leukemia (AML) and all types of acute leukemia are rapidly progressing diseases. Symptoms can appear suddenly and worsen quickly; even if recent blood tests were normal, blood count values can deteriorate and sudden symptoms can be observed within as little as a week. Therefore, it is important to pay attention to the following symptoms:

Main Symptoms of Acute Leukemia:

1. Sudden Onset of Weakness and Fatigue: The invasion of bone marrow by leukemia cells adversely affects red blood cell production. This leads to a drop in hemoglobin levels, which carry oxygen to tissues, causing anemia. Symptoms of anemia include extreme fatigue, weakness, shortness of breath while walking, palpitations, and drowsiness.
2. Bleeding Tendency: Leukemia cells can reduce the production of platelets (clotting cells), which play a critical role in blood clotting. This leads to bleeding symptoms such as gum bleeding, easy bruising on the body, and nosebleeds.
3. Infection and Inflammation: Leukemia cells in the bone marrow disrupt the production of leukocytes (white blood cells), which fight infections, and reduce their numbers. This weakening of the immune system can lead to frequent infections and associated symptoms like fever, sore throat, cough, runny nose, or skin infections.

Acute leukemias typically originate in the bone marrow and, in most cases, rapidly spread into the bloodstream. Rarely, they can also spread to other parts of the body, including lymph nodes, liver, spleen, central nervous system (brain and spinal cord), and testes. This spread can lead to additional symptoms specific to the affected organ:

Additional Symptoms Due to Organ Involvement:

* Lung and Thoracic Cavity Related Symptoms: Cough, hiccups, and shortness of breath may occur due to the spread of the disease to the lungs or enlargement of lymph nodes in the chest cavity. Shortness of breath can also be caused by severe anemia or lung infections.
* Organ Enlargement: Enlargement of the liver, spleen, or lymph nodes can be observed with the spread of leukemia cells to these organs.
* Central Nervous System Symptoms: Headache, dizziness, balance disorders, back pain, and drowsiness may indicate the spread of leukemia cells to the brain or spinal cord.
* Bone Pains: Leukemia cells invading the bone marrow can cause various bone pains.
* Gastrointestinal Symptoms: Rarely, acute leukemias can spread to the gastrointestinal system, leading to abdominal pain, constipation, nausea, and vomiting.

Important Note: The presence of one or more of the symptoms mentioned above does not confirm a diagnosis of acute leukemia. The presence of abnormalities in blood counts must also be evaluated for a definitive diagnosis.
