Leukemia Symptoms
While there are many different types of leukemia, the symptoms among these types can be similar.
Acute forms of leukemia are more aggressive, so people with one of these types of the disease are more likely to develop symptoms. Chronic leukemia patients may have no symptoms at all when they are diagnosed.
Many leukemia symptoms are due to a lack of properly functioning blood cells to carry oxygen throughout the body, fight infection and stop bleeding. Some symptoms can also be caused by low levels of hemoglobin, a protein that helps move oxygen throughout the body.
Leukemia symptoms include:
- Weakness, tiredness and fatigue. This can be caused by the leukemia itself or by the low levels of hemoglobin seen in many leukemia patients.
- Fever and frequent infections due to low counts of healthy white blood cells.
- Excessive sweating or night sweats.
- Easy bleeding and bruising, including bleeding of the gums due to low platelet levels.
- Recurrent nose bleeds
- Petechiae, a rash-like collection of pinpoint spots on the skin caused by bleeding into the skin. This is also due to low levels of platelets.
- Shortness of breath. This can be caused by low hemoglobin levels and lung infections.
- Swollen lymph nodes in the neck, underarm, stomach or groin
- Loss of appetite or a full feeling after eating very little food due to enlargement of the spleen.
- Unexplained weight loss.
- Bone and joint pain.
- For female patients, longer than normal or heavier than normal menstruation.
Some cases of leukemia can be passed down from one generation to the next. Genetic counseling may be right for you. Learn more about the risk to you and your family on our genetic testing page.
What types of cancer can cause itchy skin?
Your skin can itch for many reasons, such as allergies, insect bites and dry skin. 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. Here, I¡¯ll explain what types of cancers may cause itchy skin, what the itch feels like and when you should see a doctor.
What types of cancer can cause itchy skin?
Itching can be a sign of several types of blood cancers.
Lymphoma
- Cutaneous T cell lymphoma is a skin lymphoma that starts in the T lymphocytes.
- Hodgkin lymphoma and non-Hodgkin lymphoma?both start in the lymphatic system.
Leukemia
- Acute lymphocytic leukemia is a rare, aggressive type of blood cancer that starts in the bone marrow.
- Chronic lymphocytic leukemia and chronic myeloid leukemia are slow-growing types of blood cancer that mostly affect adults over age 55.
- Polycythemia vera is a chronic blood disorder in which the bone marrow produces too many red blood cells. People with polycythemia vera who experience itching have a higher chance of the disease developing into myelofibrosis and acute myeloid leukemia.
- Myelodysplastic syndrome is a group of diseases in which the bone marrow doesn¡¯t make enough healthy blood cells. Some cases develop into acute myeloid leukemia.
Itching can also be a sign of the following cancers:
- Liver cancer
- Bile duct cancer
- Non-small cell lung cancer
- Metastatic stomach cancer
- Pancreatic cancer
- Melanoma: Itching has been reported in 22% of primary melanoma skin lesions.
- Basal cell carcinoma
- Squamous cell carcinoma
Where on the body does the itching occur?
Itching can occur anywhere on the body, including the scalp and genitalia. The most common sites are the lower legs and the trunk ¨C that is, your chest, abdomen, pelvis and back.
How would you describe an itch that might indicate cancer?
There aren¡¯t specific characteristics to look for. What I mean is the itch can be:
- Localized (affecting one area of the body) or generalized (affecting the entire body)
- Constant or intermittent
- Mild to severe
Pruritus may be an associated symptom of cancer. That means it is often an additional symptom of the cancer itself. It¡¯s not necessarily a predictor of cancer. So, if you have itchy skin, it doesn¡¯t mean you will develop cancer.
Itching associated with pancreatic cancer
Itching can happen when pancreatic cancer causes a blockage in the bile duct, which can also lead to jaundice. In these cases, itching tends to be generalized. But I have seen pancreatic cancer patients with intense itching only on their trunk area, or/and only on the arms and legs.?
Aquagenic itch can be a sign of certain cancers
Aquagenic itch describes an itch that develops minutes after contact with water of any temperature with no visible skin rash. Aquagenic itch is commonly seen in people with polycythemia vera. Some people who have aquagenic itch develop cutaneous T cell lymphoma or myelodysplastic syndrome several years later.
How we classify pruritus and cancer
We divide cancer patients with pruritus into three categories:
- Patients who experienced itching before being diagnosed with cancer: A cancer diagnosis may come months to years after the itching begins.
- Patients who have an existing cancer and experience itching
- Patients who have itching indirectly related to cancer: This is usually due to the growth of a tumor affecting internal organs, such as invasive liver tumors.
Cancer treatment can cause itchy skin
Sometimes, cancer treatment can cause rashes and itchy skin. Chemotherapy, opioids, aspirin and antibiotics may cause itching.?
What other conditions can cause itchy skin?
Chronic pruritus can be caused by:
- Diabetes
- Chronic kidney failure
- Liver disease
- HIV infection
- Allergic reactions to food, medicine and insect bites
- Thyroid disorders
- Multiple sclerosis
- Anxiety
- Obsessive-compulsive disorder
- Depression
- Pregnancy
Remember: there are many reasons your skin may itch. Most of the time, it is not because of cancer.
When should you see a doctor for itchy skin?
See a doctor if you have itchy skin that:
- is all over the body, especially during pregnancy,
- starts suddenly,
- lasts for several weeks or longer,
- does not improve with moisturizer use,
- is persistent in the same spot,
- disrupts your sleep or distracts from your daily routine and/or
- is associated with other symptoms, such as weight loss, fever, night sweats, loss of appetite, jaundice, fatigue, cough or visible lumps.
If your doctor cannot find the reason for the itch, they may do a workup to check for other possible causes, including cancer. This workup includes a comprehensive review of your medical history and a physical examination, with particular attention to the lymph nodes. Your doctor will test your complete blood count, liver function, kidney function and thyroid function.
What else should readers know about itchy skin and cancer?
Itchy skin can be frustrating, especially if you don¡¯t know what¡¯s causing it. Itching can be a sign of internal disease, including cancer. We know that patients with certain cancers, namely lymphomas and leukemias, often have associated pruritus, but we have limited data indicating that itchy skin is a predictor of cancer. So, itchy skin alone does not mean you will get cancer.
See a doctor if you have persistent itchy skin and you develop other concerning symptoms. They can figure out what¡¯s causing the symptoms and get you the proper treatment.?
