Leukemia is a type of cancer that affects the blood-forming cells in the bone marrow and lymphatic system. The symptoms of leukemia can vary depending on the type of leukemia, age, and overall health of the person, and whether the leukemia has spread to other organs or tissues. Some common symptoms of leukemia include:

• Fatigue and weakness
• Pale skin
• Excessive sweating, especially at night
• Unintended weight loss
• Fever and chills
• Frequent infections
• Tiny red, purple, or brown spots under the skin (petechiae)
• Bone pain and tenderness
• Painless lumps (swollen lymph nodes) in the neck, underarm, stomach, or groin
• Swelling and discomfort in the midsection
• Loss of appetite
• Low blood cell levels (aplastic anemia)

Leukemia symptoms tend to become more frequent and severe with time, especially with acute myeloid and acute lymphocytic leukemias, which tend to be faster-growing and more symptomatic than chronic leukemias. It is important to note that many of these symptoms are vague and can resemble symptoms of other common illnesses, such as the flu. Therefore, it is essential to see a doctor if you have any persistent signs or symptoms that worry you.
