Because many types of leukemia show no obvious symptoms early in the disease, leukemia may be diagnosed incidentally during a physical exam or as a result of routine blood testing.
Chronic leukemia involves more-mature blood cells. These blood cells replicate or accumulate more slowly and can function normally for a period of time. Some forms of chronic leukemia initially produce no early symptoms and can go unnoticed or undiagnosed for years.
The white cells in the blood grow very quickly, over a matter of days to weeks. Sometimes a patient with acute leukemia has no symptoms or has normal blood work even a few weeks or months before the diagnosis. The change can be quite dramatic.
Leukemia Misdiagnosis
Physicians often fail to diagnose chronic leukemia, as it often shows no symptoms until the disease has begun to progress. Many of the symptoms of leukemia may also be symptoms of other illnesses, which results in a high number of misdiagnoses.
Leukemia can produce a variety of symptoms, although most are not often apparent in the earliest stages of the malignancy. The most common symptoms of leukemia—fatigue, pale skin, weight loss and night sweats—are often attributed to other less serious conditions, such as the flu.
How is leukemia diagnosed? A diagnosis of leukemia is usually made by analyzing a patient's blood sample through a complete blood count (CBC) or microscopic evaluation of the blood, or by using flow cytometry.
Unlike symptoms of the flu, which generally subside as patients get better, leukemia symptoms generally last longer than two weeks, and may include sudden weight loss, bone and joint pain and easy bleeding or bruising. Other early warning signs of leukemia include: Fever, chills. Fatigue, weakness.
In CLL, the leukemia cells grow out of control and crowd out normal blood cells. These cells often build up slowly over time. Many people don't have any symptoms for at least a few years.
Blood tests.
By looking at a sample of your blood, your doctor can determine if you have abnormal levels of red or white blood cells or platelets — which may suggest leukemia. A blood test may also show the presence of leukemia cells, though not all types of leukemia cause the leukemia cells to circulate in the blood.
Often referred to as a “silent disease,” CLL can be difficult to diagnose, because people often don't have any symptoms until later in the disease, and others have symptoms that resemble signs of other conditions, such as a cold.
Myelodysplastic syndrome refers to a group of related disorders in which abnormal blood-forming cells develop in the bone marrow. At first, these cells interfere with the production of normal blood cells. Later, these cells may become cancerous, turning into a form of leukemia .
Stage 1 – A patient has high levels of white blood cells and enlarged lymph nodes. Stage 2 – A patient has high levels of white blood cells and is anemic. He or she may also have enlarged lymph nodes. Stage 3 – A patient has high levels of white blood cells and is anemic.
During the progression of leukemia, white blood cells (neoplastic leukocytes) found in bone marrow may begin to filter into the layers of the skin, resulting in skin lesions. “It looks like red-brown to purple firm bumps or nodules and represents the leukemia cells depositing in the skin,” Forrestel says.
Chronic myeloid leukaemia (CML) is a type of cancer that affects the white blood cells and tends to progress slowly over many years. It can occur at any age, but is most common in older adults around 60-65 years of age.
People in stages 0 to II may live for 5 to 20 years without treatment. CLL has a very high incidence rate in people older than 60 years. CLL affects men more than women. If the disease has affected the B cells, the person's life expectancy can range from 10 to 20 years.
In fact, up to 1 in 5 cases of cancer may be initially misdiagnosed, according to ABCNews. Our attorneys have heard numerous horror stories from leukemia patients who describe traveling from specialist to specialist, often at great expense, only to have their disease misdiagnosed at every turn.
If you have acute leukemia, you'll feel sick within weeks of the leukemia cells forming. Acute leukemia is life-threatening and requires immediate initiation of therapy. Acute leukemia is the most common cancer in children.
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.
Doctors sometimes use imaging tests including chest x-rays, ultrasound, CT scans, MRI, and PET scans to determine whether leukemia cells have affected the bones or organs such as the kidneys, the brain, or the lymph nodes. In addition, a physical exam is an important part of diagnosis for leukemia.
CT scans help reveal swelling in the lymph nodes and organs. While these scans aren't typically necessary for diagnosing leukemia, doctors sometimes use them to find out whether there's cancer in an organ, such as the spleen.
Chronic leukemia often causes only a few symptoms or none at all. Signs and symptoms usually develop gradually. People with a chronic leukemia often complain that they just do not feel well. The disease is often found during a routine blood test.
