Leukemia is a type of cancer that affects the blood and bone marrow. It can develop in both children and adults, and it is the most common type of cancer in children.

The disease originates from the abnormal growth of blood cells, which can lead to a range of symptoms. While leukemia is typically associated with bone and joint pain, and fatigue, there are other early warning signs of the disease that are just as important to look out for.

Recognizing these signs and seeking medical treatment early on can increase the chances of success in treatment.

1. Unexplained Fever

One of the early warning signs of leukemia is an unexplained fever that lasts for more than a few days. The fever can be accompanied by other flu-like symptoms, such as chills and fatigue.

A fever can indicate that the body’s immune system is trying to fight off an infection, but it can also be a sign that the blood is not functioning properly.

2. Fatigue

Another early warning sign of leukemia is fatigue. This is different from normal tiredness, and can be so severe that it affects the ability to carry out daily tasks.

Fatigue is caused by the buildup of abnormal blood cells in the body, which can also cause weakness and shortness of breath.

3. Frequent Infections

People with leukemia are more susceptible to infections, which can be caused by the body’s weakened immune system.

Frequent infections can be a sign that the disease is progressing, and they can also be a side effect of treatments such as chemotherapy.

4. Bruising and Bleeding

Leukemia can cause low levels of platelets in the blood, which can lead to excessive bruising and bleeding. Even small cuts or injuries can cause significant bleeding, and bruises may appear without an apparent cause.

This symptom can be a sign that the disease is affecting the body’s ability to control bleeding.

5. Abnormal Weight Loss

Unexplained weight loss can be a sign of many different medical conditions, including leukemia.

This symptom is caused by the abnormal growth of blood cells, which can lead to a loss of appetite and a decrease in the body’s ability to absorb nutrients.

6. Joint and Bone Pain

Leukemia can cause pain in the bones and joints, especially in the hips and spine. This pain is caused by the buildup of abnormal blood cells in the bone marrow, which can put pressure on the bones and joints.

The pain may be constant or intermittent, and can be mistaken for other conditions such as arthritis.

7. Enlarged Lymph Nodes

Leukemia can cause the lymph nodes to become enlarged, which can be felt as lumps under the skin. The lymph nodes can be found in different parts of the body, including the neck, armpits, and groin.

Enlarged lymph nodes are a sign that the body is trying to fight off an infection or disease.

8. Abdominal Discomfort

Leukemia can cause a feeling of fullness in the abdomen, which can be mistaken for indigestion or bloating. This symptom is caused by the buildup of abnormal blood cells in the spleen, liver, or lymph nodes in the abdomen.

9. Skin Rashes

Leukemia can cause skin rashes and itching, which are caused by the abnormal growth of blood cells in the skin. The rashes are typically red or purple, and may be accompanied by itching or burning.

If you are experiencing any of these warning signs, it is important to speak to your healthcare provider. Early treatment can improve outcomes, and there are many treatment options available for people with leukemia.
