Chronic fatigue or unexplained bruising is often the first sign of leukemia due to the disease's impact on blood cell production. In leukemia, the bone marrow produces abnormal white blood cells that can crowd out healthy cells, leading to a decrease in red blood cells and platelets. This decrease can result in chronic fatigue, as the body struggles to deliver enough oxygen to tissues, causing a feeling of constant tiredness. Additionally, the reduced platelets can lead to easy bruising or bleeding, as these cells are crucial for proper blood clotting.

Frequent headaches might be a symptom associated with other conditions affecting the blood or nervous system but are not specifically indicative of leukemia. Severe abdominal pain could occur if leukemia spreads to organs in the abdominal cavity but is not a common initial symptom. Persistent coughing could suggest respiratory involvement or infection, but it doesn't relate specifically to the early signs of leukemia either. Understanding these distinctions helps in recognizing leukemia symptoms early on and acting promptly.
