Leukemia is a cancer of the blood that begins in the bone marrow, where the body's blood cells are made. It causes the bone marrow to produce abnormal white blood cells that grow and divide uncontrollably, crowding out healthy blood cells. This can affect many parts of the body, including the blood, bones, heart, muscles, digestive system, and immune system. While leukemia does not directly eat muscle, it can lead to muscle weakness and wasting, especially during cancer treatment. Additionally, leukemia treatments such as chemotherapy and radiation can cause side effects like nausea, vomiting, and loss of appetite, which can contribute to weight and muscle loss. Maintaining proper nutrition and engaging in regular physical activity, including strength training exercises, can help mitigate muscle wasting in people with leukemia.

What You'll Learn
Leukemia affects the blood, bone marrow, and immune system
Leukemia is a cancer that affects the blood, bone marrow, and immune system. It starts when the DNA of a single cell in the bone marrow mutates and can't develop or function normally. This uncontrolled growth takes place in the bone marrow, where most of the body's blood is made.
As a result, the body begins producing too many immature white blood cells, which are cancerous and overwhelm the other cells in the bloodstream. Over time, this can affect red blood cells, platelets, and healthy white blood cells, leading to conditions such as anemia. Leukemia cells can also gather in the liver and spleen, causing bloating and a feeling of fullness, making it hard to eat. Additionally, treatments like chemotherapy and radiation can cause nausea and vomiting, leading to a loss of appetite.
Leukemia can cause a range of symptoms, including weakness, dizziness, nausea, easy bruising, and pale skin. These symptoms occur because leukemia affects different body parts. Some symptoms only appear if the cancer spreads beyond the blood or bone marrow, but others may be present early on. For example, leukemia can impact the digestive system, causing gum bleeding, mouth discomfort, and difficulty eating. It can also damage blood vessels and cause capillaries to burst, leading to small red or purple dots on the skin (petechiae).
Leukemia also affects the immune system, as most types originate inside the lymphocytes, which are white blood cells that play a crucial role in immune function. Chronic lymphocytic leukemia (CLL) disrupts the normal functioning of lymphocytes, leading to a weakened immune system. This leaves patients more susceptible to secondary illnesses and a higher risk of other cancers, especially skin cancers. CLL also affects the functioning of T cells, which are responsible for the autoimmune response, and patients may develop autoimmune phenomena where their immune system attacks its own red blood cells and platelets.

Treatments for leukemia can cause muscle wasting
Leukemia is a cancer of the blood that can affect many parts of the body, including the blood, bones, heart, muscles, digestive system, and brain. The disease causes the bone marrow to produce abnormal white blood cells (WBCs), which are cancerous and overwhelm the other cells in the bloodstream. This can lead to a range of symptoms, including weakness, dizziness, nausea, easy bruising, and a pale skin complexion.
While leukemia itself can cause muscle weakness, treatments for leukemia can also cause muscle wasting, known as cachexia. Cachexia is a severe and disabling clinical condition that frequently accompanies the development of many types of cancer, including leukemia. It is characterised by muscle wasting, which can lead to physical impairment, poor quality of life, reduced tolerance to treatments, and shorter survival. Cachexia affects 50-80% of cancer patients, and up to 80% of those who develop cachexia will die.
The intense treatments for leukemia, such as chemotherapy and radiation, can contribute to muscle wasting. Chemotherapy, in particular, can extirpate blood cells, causing hypoxia and suppressing the immune response. This can lead to incapacitation due to fatigue and an increased risk of infection. Additionally, the processes that maintain muscle mass and function are compromised, leading to muscle damage and wasting.
The impact of chemotherapy on skeletal muscle has become increasingly recognised. Anthracyclines, a class of chemotherapy drugs used to treat acute lymphocytic leukemia and acute myeloid leukemia, have been linked to cardiomyopathy, a key risk factor associated with their limited clinical utility in leukemia treatment. Furthermore, the induction regimen and HCT conditioning programme for acute myeloid leukemia can enhance the risk of multi-organ toxicity, promoting morbidity and mortality, especially in older patients.
To mitigate the risk of muscle wasting during leukemia treatment, patient stratification is used to consider factors such as body mass and skeletal muscle mass when determining a patient's suitability for treatment options. Additionally, maintaining proper nutrition and engaging in moderate-intensity physical activity can help prevent or slow down muscle wasting. Working closely with a registered dietitian can ensure that individuals with leukemia receive adequate nutrition during their treatment and recovery.

Nutritional support can help prevent muscle wasting
Leukemia is a cancer of the blood that begins with the body producing too many immature white blood cells. Over time, this affects the red blood cells, platelets, and healthy white blood cells, leading to conditions such as anaemia. The disease can spread to other parts of the body, including the bones, heart, digestive system, and brain.
Leukemia and its treatment can cause muscle weakness, which can be an early contributor to a poor quality of life. The disease and its treatment can also cause a loss of appetite, nausea, and vomiting, which can lead to a lack of nutrition. This can cause weight loss and muscle wasting.
It is also important to prioritize nutrient-dense, high-calorie foods to maintain weight and preserve lean muscle mass. This can include nutrient-rich foods like flaxseed meal, chia seeds, nut butters, beans, and vegetables. Increasing meal frequency by eating small snacks throughout the day can also help obtain adequate calories.
In addition to nutritional support, strength training exercises can help prevent or slow down muscle wasting. It is important to consult with a clinician before starting a new exercise program to ensure it is safe based on the individual's condition and treatment plan.

Leukemia can cause muscle pain and tenderness
Leukemia is a cancer of the blood that begins in the bone marrow, where the body's blood cells are made. It causes the bone marrow to produce abnormal white blood cells that grow and divide uncontrollably, crowding out healthy blood cells. This can affect many parts of the body, including blood, bones, the heart and other muscles, the digestive system, and the immune system.
The nature of muscle discomfort in individuals with leukemia can vary. Some patients report sharp pain, while others experience a dull, continuous ache. This pain tends to linger during rest and can be a distinguishing factor from typical muscle aches that usually come and go, flaring after physical activity.
It is important to note that muscle weakness and pain are also side effects of certain medications used to treat leukemia. Drugs called anthracyclines, which are the standard therapy for acute types of leukemia, can increase the risk of heart failure when administered in high doses over a short period due to their toxicity. This can indirectly impact muscle health and function.
To manage muscle pain and tenderness associated with leukemia, individuals may find relief through moderate-intensity physical activity, such as strength training exercises. These activities can help prevent or slow down muscle wasting during cancer treatment. However, it is crucial to listen to your body and only engage in physical activities that feel comfortable and do not cause pain or discomfort. Consulting with a clinician before starting an exercise program is advisable to ensure safety.

Leukemia does not directly eat muscle but causes muscle weakness
Leukemia is a cancer of the blood that begins in the bone marrow, where the body's blood cells are made. It causes the bone marrow to produce abnormal white blood cells that grow and divide uncontrollably, crowding out healthy blood cells. This can affect many parts of the body, including blood, bones, the heart and other muscles, and the digestive system. Leukemia also affects the immune system, increasing the risk of infections.
While leukemia does not directly eat muscle, it can cause muscle weakness, which is often one of the earliest contributors to a poor quality of life in children with leukemia. This muscle weakness can be a result of the cancer itself or the treatment, which can include chemotherapy and radiation. Chemotherapy and radiation can cause nausea and vomiting, leading to a lack of appetite and decreased food intake. Additionally, certain medications used to treat leukemia, such as anthracyclines, may increase the risk of heart failure, which can indirectly impact muscle health.
Furthermore, leukemia can lead to anemia, a blood disorder that occurs when the body does not produce enough healthy red blood cells. Anemia can cause a reduction in red blood cells, resulting in low iron levels and a decrease in oxygen supply to the tissues, which can lead to body aches and muscle pain. Leukemia-related anemia can also contribute to joint pain and inflammation, as abnormal white blood cells accumulate in the joints and bone marrow.
To manage muscle weakness and maintain muscle mass during leukemia treatment, a nutrient-rich diet and regular physical activity are recommended. Eating a nutritious diet can help ensure that the body is getting the energy and nutrients it needs to support the immune system and maintain muscle health. Moderate-intensity physical activity, such as strength training exercises, can help prevent or slow down muscle wasting and improve energy levels and mood. However, it is important to listen to your body and only engage in physical activities that feel comfortable and do not cause pain or discomfort.
