Leukemia is a type of cancer that affects the blood and bone marrow. The first signs of leukemia can be vague and similar to those of other illnesses, so it is important to seek medical advice if you have concerns. The most common early symptoms of leukemia include:

• Fatigue and weakness: This can be caused by a shortage of normal blood cells, which can occur when abnormal cells crowd out healthy blood cells in the bone marrow.

• Pale skin: This can also be caused by a shortage of red blood cells.

• Excessive sweating, especially at night: This can be a symptom of leukemia, but it is also a symptom of many other conditions.

• Unintended weight loss: This can occur when abnormal cells in the body use up more energy than normal cells, leading to weight loss.

• Fever and chills: These can be caused by infections, which are more common in people with leukemia due to a weakened immune system.

• Frequent infections: This can be a sign of leukemia, as abnormal cells in the body can weaken the immune system.

• Tiny red, purple or brown spots under the skin (petechiae): These are caused by bleeding under the skin and can be a sign of low platelet counts, which can occur in leukemia.

• Bone pain and tenderness: This can be caused by abnormal cells accumulating in the bone marrow.

It is important to note that these symptoms can vary depending on the type of leukemia and the persons age and overall health. Additionally, faster-growing forms of leukemia, known as acute leukemias, may have more pronounced and identifiable symptoms. If you have any persistent signs or symptoms that worry you, make an appointment with your doctor.
