Blood tests are not used to diagnose lymphoma, but they can sometimes help determine how advanced the lymphoma is.
Complete blood count (CBC).
This test measures the number of blood cells in a sample, including red blood cells, white blood cells, and platelets. A low level of red blood cells, white blood cells or platelets may indicate that the lymphoma is present in the bone marrow and/or blood.
To diagnose non-Hodgkin lymphoma, NYU Langone doctors perform a biopsy, in which they take a tissue sample from a swollen lymph node found during the physical exam or with imaging tests, such as CT, PET, or MRI, which doctors often use when diagnosing cancer, and evaluate it under a microscope.
Myth: A blood test can diagnose cancer on its own. Fact: Many cancers cause hormonal and metabolic changes that are detected by a blood test, known as tumour markers. But usually, a blood test on its own isn't enough for a diagnosis. The results could be caused by other conditions that aren't cancer.
The best way to find lymphoma early is to pay attention to possible signs and symptoms. One of the most common symptoms is enlargement of one or more lymph nodes, causing a lump or bump under the skin which is usually not painful. This is most often on the side of the neck, in the armpit, or in the groin.
The most common symptom of Hodgkin lymphoma is one or more enlarged (swollen) lymph nodes. The enlarged lymph node may be in the neck, upper chest, armpit, abdomen or groin. The swollen lymph node is usually painless.
Most types of lymphoma can't be diagnosed by a blood test. However, blood tests can help your medical team find out how lymphoma and its treatment are affecting your body.
While infections and inflammation are more often to blame for an increase in white blood cell counts, some cancers can increase your WBC count as well. This condition, called leukocytosis, can occur in some of the same cancers that cause WBCs to drop, like leukemia and lymphoma.
extreme tiredness – tiredness that doesn't go away even after rest or sleep (fatigue) chest pain, cough or breathlessness if there's a swelling in your chest. feeling uncomfortably full or feeling sick caused by a swelling in your stomach area. itching either widespread or in one place.
The only way to be absolutely sure of a diagnosis of lymphoma (or any other cancer) is for a doctor to conduct medical tests including performing an excisional biopsy to remove an entire lymph node or an incisional biopsy to remove a portion of the diseased tissue.
Lymphomas can start anywhere in the body where lymph tissue is found. The major sites of lymph tissue are: Lymph nodes: Lymph nodes are bean-sized collections of lymphocytes and other immune system cells throughout the body, including inside the chest, abdomen, and pelvis.
Certain areas of skin may also thicken, harden and form plaques that itch and ulcerate. Typically, these plaques develop on the face or buttocks or within skin folds. As a skin lymphoma rash progresses, papules (small bumps) may start to appear.
Certain types of cancer, including lymphoma, may lead to an abnormally high white blood cell count. A high WBC count, also known as lymphocytic leukocytosis, can also indicate an existing infection or dysfunction in the immune system.
Low-Grade Lymphoma
These grow so slowly that patients can live for many years mostly without symptoms, although some may experience pain from an enlarged lymph gland. After five to 10 years, low-grade disorders begin to progress rapidly to become aggressive or high-grade and produce more severe symptoms.
Higher-than-normal numbers of lymphocytes or monocytes can indicate the possibility of certain types of cancer. Some cancers and their treatment may cause low numbers of neutrophils, a condition called neutropenia.
The median WBC count among people with CML is 100,000/μl , but it can climb higher. Some sources note that people with acute or chronic leukemia may have a WBC count in the 100,000–400,000 range. As high WBC counts may indicate other conditions, doctors will conduct additional tests to help rule out or confirm CML.
The fatigue felt by people with cancer is different from the fatigue of daily life and different from the tired feeling people might remember having before they had cancer. People with cancer might describe it as feeling very weak, listless, drained, or “washed out” that may decrease for a while but then comes back.
Blood tests aren't used to diagnose HL, but they can help your doctor get a sense of how advanced it is and how well you might tolerate certain treatments. The complete blood count (CBC) is a test that measures the levels of different cells in the blood. People with HL can sometimes have abnormal blood counts.
NHL is a difficult disease to diagnose, therefore you may want to get a second opinion by an experienced hematopathologist before you begin treatment. Some types of NHL can be confused with one other. The appropriate treatment depends on having the correct diagnosis.
CT scans can show up swollen (enlarged) lymph nodes in your body. If you had a CT scan to help diagnose Hodgkin lymphoma, you won't need to have another one. But if you were diagnosed by lymph node biopsy alone, you'll have a CT scan to look for enlarged nodes in other parts of your body.
Common symptoms of having lymphoma include swelling of lymph nodes in your neck, in your armpits or your groin. This is often but not always painless and often could be associated with fevers, or unexplained weight loss, or drenching night sweats, sometimes chills, persistent fatigue.
Hodgkin lymphoma most commonly affects lymph nodes in the neck or in the area between the lungs and behind the breastbone, which is called the mediastinum. It can also begin in groups of lymph nodes under an arm, in the groin, or in the abdomen or pelvis.
Common symptoms of lymphoma
Some people may not have any symptoms at all, and are diagnosed accidentally when having a scan for another medical condition. If you have an aggressive (fast-growing) lymphoma, you will likely notice your symptoms as they develop over a short period of time, such as days to weeks.
