Yes, leukemia can cause itching (pruritus) due to the abnormal blood cells affecting the skin, immune responses, or as a side effect of treatment, often alongside other symptoms like fatigue, fever, or easy bruising, though other causes of itching are more common. It's a recognized symptom, especially with certain blood cancers like acute myeloid leukemia or polycythemia vera, and can appear as generalized itchiness or a rash.
Some common areas where people with blood cancer experience itching are on the torso, back, legs and arms. The sensation can come and go in short bursts or it may last for long periods of time.
One of the earliest signs of leukemia is often persistent fatigue and weakness, stemming from anemia, alongside frequent infections, easy bruising, or unusual bleeding (like nosebleeds/gum bleeding) due to issues with blood cell production. Other common early indicators include fever, night sweats, unexplained weight loss, and swollen lymph nodes.
The itch, called pruritus, will usually go away once you treat what's causing it. But sometimes an itch can be chronic, meaning it lasts six weeks or longer. This is known as chronic pruritus. In rare cases, chronic pruritus can be a sign of cancer.
Itchy skin can signal various cancers, including skin cancers (melanoma, basal/squamous cell), blood cancers (lymphoma, polycythemia vera, leukemia), and internal organ cancers like liver, pancreatic, or bile duct cancers, often due to immune responses or bile buildup; persistent, unexplained itching, especially with other symptoms like jaundice or new skin changes, warrants medical investigation.
Examples include dry skin (xerosis), eczema (dermatitis), psoriasis, scabies, parasites, burns, scars, insect bites and hives. Internal diseases. Itching on the whole body might be a symptom of an underlying illness, such as liver disease, kidney disease, anemia, diabetes, thyroid problems and certain cancers.
With lymphoma, you can itch anywhere on your body, but it's common on the lower legs, hands, feet, torso (between waist and shoulders), or near affected lymph nodes, often worsening at night and without a typical rash, feeling deep and unrelieved by scratching. This itchiness is caused by immune chemicals (cytokines) irritating nerve endings, and can be a symptom of both Hodgkin and non-Hodgkin lymphoma.
You should worry about itchy skin if it's severe, lasts more than a couple of weeks, disrupts sleep, covers your whole body without a clear cause, or comes with other symptoms like fever, weight loss, night sweats, fatigue, jaundice, or a spreading rash that's bleeding, crusting, or has pus, as it could signal underlying issues like eczema, psoriasis, infections, liver/kidney disease, thyroid problems, nerve disorders, or even some cancers. Seek immediate care if you have trouble breathing or a swollen tongue.
Common signs and symptoms of lymphoma
Sometimes skin cancer may start as a flat discoloured patch. Cancerous patches can be a range of colours, including purple, brown and red. The patches may be darker on brown or black skin. Sometimes the patches may look crusty and feel rough or itchy.
Leukemia symptoms commonly include fatigue, breathlessness, infections, and bruising or bleeding more easily. Leukemia* symptoms vary depending on the type of leukemia. Not everyone gets the same symptoms, and you won't necessarily have all of the symptoms.
Some people with leukemia or myelodysplastic syndromes have bone or joint pain. This bone pain is most often felt in the long bones of the arms and legs, in the ribs, and in the breastbone.
Leukemia starts in the soft, inner part of the bones (bone marrow), but often moves quickly into the blood. It can then spread to other parts of the body, such as the lymph nodes, spleen, liver, central nervous system, and other organs.
A complete blood count can provide evidence of an internal condition causing your itch, such as anemia. Tests of liver and kidney function. Liver or kidney disorders and thyroid conditions, such as hyperthyroidism, can cause itching.
Symptoms of leukemia
Dry skin: Your body loses moisture at night, which can make your skin itchy. Hormonal changes: At night, your body doesn't produce as many hormones as it does during the day and certain hormones reduce inflammation (swelling). As you have fewer hormones at night, your skin could be itchy.
The most common symptom of lymphoma is a painless swelling or lump in the neck, armpit or groin. This is caused by lymphoma cells building up in the lymph nodes, which makes them bigger.
The term “B symptoms” is used to refer to fever, drenching night sweats, and loss of more than 10 percent of body weight over six months. B symptoms are important to the prognosis and staging of the disease.
Early-stage lymphomas may not cause symptoms. When they happen, symptoms of lymphoma may include: Swollen lymph nodes, which might feel like a lump under the skin. They happen most often in the neck, armpit and groin.
rashes can be caused by a low level of platelets. Some people with blood cancer experience itching, it is not understood what causes this. What you might expect: You may notice small red spots in the skin (petechiae) or a purple rash (purpura)
You may notice that itching gets worse when it's hot or at night when you're trying to sleep. Itchiness can develop when your immune system reacts to lymphoma by releasing chemicals that can irritate your skin. You could also feel a burning sensation.
Itching (pruritus) in the body can stem from several nutrient deficiencies, with iron deficiency anemia being a common culprit, causing dry, itchy skin. Other potential deficiencies linked to itching include vitamin D, essential fatty acids, B vitamins (like B12), and minerals like calcium, zinc, and copper, affecting skin health, hydration, and histamine regulation.
How patients described their first signs of lymphoma
There isn't a blood test that will show whether or not you have lymphoma. But blood tests can check your general health and can sometimes pick up problems caused by lymphoma. Blood tests can check: how well your liver and kidneys are working.
Psoriasis is an autoimmune skin condition that causes itchiness and discomfort. Plaque psoriasis is the most common type. It causes thick, scaly areas of skin. While there isn't a cure, psoriasis treatment can help manage symptoms.
