Leukemia is a type of cancer that affects the blood and bone marrow, and its symptoms can vary depending on the type of leukemia. Some common signs and symptoms of leukemia include:

• Fever or chills
• Persistent fatigue, weakness
• Frequent or severe infections
• Losing weight without trying
• Swollen lymph nodes, enlarged liver or spleen
• Easy bleeding or bruising
• Recurrent nosebleeds
• Tiny red spots in your skin (petechiae)
• Excessive sweating, especially at night
• Bone pain or tenderness
• Tiredness and/or anemia (pale complexion, weakness, and breathlessness)
• Repeated infections (mouth sores, sore throat, fevers, sweats, coughing, frequent passing of urine with irritation, infected cuts and scratches, and boils)
• Increased bruising and bleeding
• Night sweats
• Discomfort in bones or joints
• Enlarged spleen, liver, or lymph nodes
• Pain or feeling of fullness below the ribs
• Unexplained weight loss or loss of appetite
• Wheezing, coughing, or painful breathing

It is important to note that leukemia symptoms are often vague and not specific, and they may resemble symptoms of the flu and other common illnesses. Sometimes leukemia is discovered during blood tests for some other condition. If you have any persistent signs or symptoms that worry you, make an appointment with your doctor.
