Leukemia diagnosis

• • Analysis of blood sample through a complete blood count, microscopic evaluation or flow cytometry • • For people whose bone marrow may be producing abnormal blood cells • • The next step may be molecular testing to evaluate the cytogenetics (the cells' chromosomes) • • Involves Pathology, Pediatric Hematology & Oncology, and Hematology Leukemia is cancer of bone marrow stem cells – immature cells that normally would develop into either red blood cells, white blood cells or platelets. When someone has leukemia, the bone marrow produces abnormal blood cells that do not die when they become old, as normal, healthy cells do. These abnormal cells build up in the bone marrow and prevent normal blood cells from developing. Almost all leukemia begins in the bone marrow, and it usually spreads to the blood. Leukemia may also be found in other tissues, such as lymph nodes and the spleen. Diagnosing leukemia in its earliest stages can improve a patient’s prognosis, so it is important to be tested as soon as possible if leukemia is suspected. Just as there are several forms of blood cells, there are different types of leukemia. Leukemia is classified as either acute or chronic, according to which type of blood cell is improperly reproduced. “Acute leukemia is made of blasts, immature cells, while chronic leukemia is made of more mature cells,” says Yale Medicine pathologist Leukemia that affects myeloid cells, which would normally develop into red blood cells, platelets or granulo...

Leukemia starts when the DNA of a single cell in your bone marrow changes (mutates) and can’t develop and function normally. Leukemia cells often behave like abnormal white blood cells. Treatments for leukemia depend on the type of leukemia you have, your age and overall health, and if the leukemia has spread to other organs or tissues. Overview Normal blood contains red blood cells, white blood cells and platelets. Leukemia cells outnumber the normally seen healthy blood cells. What is leukemia? Leukemia is a Unlike other There are many types of leukemia. Some are more common in children, while others are more common in adults. Treatment depends on the type of leukemia and other factors. How does leukemia develop? Leukemia begins in bone marrow, the soft spongy tissue in the inner cavity of your bones, where your body’s blood cells are made. Blood cells go through multiple stages before reaching their fully mature forms. Mature, normal blood cells include: • Red blood cells : Cells that carry oxygen and other vital materials to all tissues and organs in your body. • White blood cells : Cells that fight infection. • Platelets : Cells that help your blood clot. These blood cells start as hematopoietic (hemo = blood, poiesis = make) stem cells. The • Myeloid cells develop into red blood cells, platelets and certain types of white blood cells ( • Lymphoid cells develop into certain white blood cells ( However, if you have leukemia, one of the developing blood cells begins to ...

Leukemia is a cancer of the blood cells. There are several broad categories of blood cells, including red blood cells (RBCs), white blood cells (WBCs), and platelets. Generally, leukemia refers to cancers of the WBCs. WBCs are a vital part of your immune system. They protect your body from invasion by: • bacteria • viruses • fungi • abnormal cells • foreign substances In leukemia, the WBCs do not function like normal WBCs. They can also divide too quickly and eventually crowd out normal cells. • • • Once formed, WBCs travel through your bloodstream and lymphatic vessels to fight infection in the body’s tissues. The symptoms of leukemia may • • • • • painless, • enlarged • red spots on the skin, called • • • frequent infections Leukemia can also cause symptoms in organs that have been infiltrated or affected by the cancer cells. For example, if the cancer spreads to the central nervous system, it can cause: • • • • loss of muscle control • How the cancer spreads depends on the type of leukemia and how aggressive it is. Leukemia can also spread to other • • • • • The onset of leukemia can be acute (sudden onset) or chronic (slow onset). In acute leukemia, cancer cells multiply quickly. In chronic leukemia, the disease progresses slowly and early symptoms may be very mild. Leukemia is also classified according to the type of cell that’s affected. Leukemia involving myeloid cells is called myeloid or myelogenous leukemia. Myeloid cells are immature blood cells that would norma...

Chronic myelomonocytic leukemia (CMML) is a kind of You may have heard of the Most of the time, leukemia affects leukocytes, or white blood cells. CMML is a rarer type of leukemia that affects myeloid stem cells in your blood marrow. Keep reading to learn more about what CMML is, which symptoms to look out for, and how it’s diagnosed and treated. CMML affects myeloid stem cells in your bone marrow. These are stem cells that produce blood cells like: • Red blood cells (RBCs). These cells carry oxygen and other nutrients to your body’s organs and tissues. • White blood cells (WBCs). Called granulocytes and monocytes, these cells respond to infections and disease. • Platelets. These cells form blood clots to help stop bleeding. When you have CMML, you have an increased number of monocytes in your blood ( The overabundance of monocytes and blasts crowds out healthy blood cells like RBCs, platelets, and granulocytes. This leads to the symptoms of CMML. CMML is classified as a myelodysplastic/myeloproliferative neoplasm. This is because, while CMML is its own distinct condition, it shares features of two other conditions: • Myelodysplastic syndromes (MDS). • Myeloproliferative neoplasms (MPNs). MPNs are abnormal growths where your myeloid stem cells produce higher-than-normal levels of RBCs, WBCs, or platelets. These RBCs, WBCs, or platelets don’t function like they usually do. MPNs can also progress to AML. How common is CMML? CMML is a rare type of leukemia. The The majority o...

You’ll probably have a • White blood cells (leukocytes). White blood cells help fight infection. If your white blood cell count is low, your risk of infections grows. • Red blood cells (erythrocytes). Red blood cells carry oxygen from the lungs to the rest of your body and return with carbon dioxide. If your red blood cell count is low, your tissues may lack oxygen, which can lead to fatigue, weakness, dizziness, and headaches. • Platelets. Platelets help your blood clot and control bleeding. If your platelet count is low, it can lead to excessive bleeding and easy bruising, even from minor cuts and bumps. The CBC will also include measurements of: • Hemoglobin. This is a protein that red blood cells need to distribute oxygen. • Hematocrit. Hematocrit is the amount of blood taken up by red blood cells.

Leukemia is a type of cancer that harms the body's ability to make healthy blood cells. It starts in the bone marrow, the soft center of various bones. This is where new blood cells are made. There are three main types of blood cells: • red blood cells carry oxygen from the lungs to the body's tissues and take carbon dioxide to the lungs • platelets help blood to clot • white blood cells fight infections, viruses, and diseases Leukemia usually refers to cancer of the white blood cells. It tends to affect one of the two major types of white blood cells: lymphocytes and granulocytes. These cells circulate through the bloodstream and the lymph system to help the body fight off viruses, infections, and other invading organisms. Leukemia arising from cancerous lymphocytes is called lymphocytic leukemia; leukemia from cancerous granulocytes is called myeloid or myelogenous leukemia. Leukemia is either acute (comes on suddenly) or chronic (lasts a long time). Acute leukemia affects adults and children. Chronic leukemia rarely affects children. Leukemia can occur due to • genetic abnormalities • exposure to radiation and chemicals such as benzene (found in unleaded gasoline) and other hydrocarbons • exposure to agents used to cure or control other cancers, including radiation Leukemia is usually not inherited. It tends to happen to people without any family history of the disease. Some forms of leukemia, though, such as chronic lymphocytic leukemia, strike close relatives in the s...

AML is classified by subtypes, while CML is classified by phases. In AML, the disease comes on quickly, and without treatment, the affected person tends to decline rapidly. With CML, the condition comes on slowly and worsens over time. AML is far more common, affecting both kids and adults, while CML primarily affects older people. AML subtypes depend on the specific system used to classify them. A 2016 study of 1,540 people with AML identified at least 11 major types based on their genetic changes. Chronic Myeloid Leukemia In many cases of chronic myeloid leukemia, some DNA between chromosomes 9 and 22 is partially swapped in a process known as translocation. In almost all CML patients, this makes chromosome 22 shorter than usual—something dubbed the • Chronic phase, which can last for years. During that time, the makeup of blood and bone marrow contains less than 10% blast cells. • Accelerated phase, with higher counts of blasts and often with new genetic changes. • Blast phase, with a fever, enlarged spleen, and other symptoms due to high blast counts. CML • Slower disease progression • Accounts for just 15% of leukemias, more often affecting older adults • Symptoms include night sweats, unexplained weight loss • May appear on routine blood tests due to lack of symptoms • Treated with targeted therapy before other options • Classified by CML phases AML • Rapid disease progression • Second most common leukemia, affecting both adults and children • Symptoms include bone p...
