What Are the Types of Lymphoma?



What Are the Types of Lymphoma?

Lymphomas fall into one of two major categories: Hodgkin's lymphoma (HL, previously called Hodgkin's disease) and all other lymphomas (non-Hodgkin's lymphomas or NHLs).
  • These two types occur in the same places, may be associated with the same symptoms, and often have similar appearance on physical examination (for example, swollen lymph nodes). However, they are readily distinhttp://lymphomacancers.blogspot.com.tr/guishable via microscopic examination of a tissue biopsy sample because of their distinct appearance under the microscope and their cell surface markers.
  • Hodgkin's disease develops from a specific abnormal B lymphocyte lineage. NHL may derive from either abnormal B or T cells and are distinguished by unique genetic markers.
  • There are five subtypes of Hodgkin's disease and about 30 subtypes of non-Hodgkin's lymphoma (not all experts agree on the numbers and names of these NHL subtypes).
  • Because there are so many different subtypes of lymphoma, the classification of lymphomas is complicated (it includes both the microscopic appearance as well as genetic and molecular markers).
  • Many of the NHL subtypes look similar, but they are functionally quite different and respond to different therapies with different probabilities of cure. For example, the subtype plasmablastic lymphoma is an aggressive cancer that arises in the oral cavity of HIV-infected patients, the follicular subtype is composed of abnormal B lymphocytes, while anaplastic subtype is comprised of abnormal T cells and cutaneous lymphomas localize abnormal T cells in the skin. As previously mentioned, there are over 30 subtypes of NHL with unusual names such as Mantle cell lymphoma, mucosa associated lymphoid tissue (MALT) lymphoma, hepatosplenic lymphoma and hereditary lymphomas. However, the World Health Organization (WHO) suggests there at least 61 types of NHL; subtyping is still a work in progress. However, no matter how many subtypes experts suggest exist, there are too many to discuss in detail in this article. HL subtypes are microscopically distinct, and typing is based upon the microscopic differences as well as extent of disease.
Lymphoma is the most common type of blood cancer in the United States. It is the seventh most common cancer in adults and the third most common in children. Non-Hodgkin's lymphoma is far more common than Hodgkin's lymphoma.
  • In the United States, about 72,580 new cases of NHL and 8,500 new cases of HL were expected to be diagnosed in 2016, and the overall incidence is increasing each year.
  • About 20,150 deaths due to NHL were expected in 2016as well as 1,120 deaths due to HL, with the survival rate of all but the most advanced cases of HL greater than that of other lymphomas.
  • Lymphoma can occur at any age, including childhood. Hodgkin's disease is most common in two age groups: young adults 16-34 years of age and in older people 55 years of age and older. Non-Hodgkin's lymphoma is more likely to occur in older people. Continue Reading

Lymphoma Cancer Signs & Symptoms

Lymphoma Cancer Signs & Symptoms


Symptoms of lymphoma are similar to those of other diseases and afflictions. The most common symptom is a painless swelling in a lymph node (called lymphadenopathy). People often first go to the doctor because they think they have a cold or respiratory infection that will not go away. The neck or armpits are common places noticed first, but the swelling can occur in other parts of the body including the groin (that may cause swelling in the legs or ankles) or the abdomen (that can cause cramping and bloating). Some lymphoma patients notice no swelling at all while others may complain of night sweats, weight loss, chills, a lack of energy or itching. There is usually no pain involved, especially when the lymphoma is in the early stage of development.

Most people who have nonspecific complaints such as these will not have lymphoma. However, it is important that any person who has symptoms that persist see a doctor to confirm that no lymphoma or serious illness are present. The doctor will perform a complete physical examination and look for swollen lymph nodes under the chin, in the neck and tonsil area, on the shoulders and elbows, armpits, and in the groin. The doctor will also examine other parts of the body to see whether there is swelling or fluid in your chest or abdomen that could be caused by swollen lymph nodes.


You will be asked about pain and examined for any weakness or paralysis that could be an enlarged lymph node pressing against nerves or the spinal cord. Your abdomen will be examined to see whether any internal organs are enlarged, especially the spleen. If the doctor suspects lymphoma, he or she will likely order further tests including a biopsy, blood tests, x-rays and perhaps a bone marrow evaluation.

The symptoms of lymphoma are commonly seen in other, less serious illnesses, such as influenza or other viral infection. These symptoms are often overlooked, but in cases of less serious illnesses they would not last very long. With lymphoma, these symptoms persist over time and cannot be explained by an infection or another disease. The checklist below lists the most common symptoms of lymphoma.

Because of the common nature of these symptoms and because lymphoma symptoms do not appear in all cases, diagnosis is often problematic.

If you suspect that you, a family member, friend or loved one may have lymphoma, see your doctor or qualified medical professional as soon as possible. Early diagnosis makes an impact on treatment and outcome.

Painless swelling in the upper body lymph nodes, i.e., the neck, collarbone region, armpits or groin. (A swollen lymph node is normally NOT as painful as an infected lymph node, which is common and can be painful.) This checklist lists the most common symptoms of lymphoma:

Chills/temperature swings
Fevers (especially at night)
Unexplained weight loss
Loss of appetite
Unusual tiredness/lack of energy
Persistent coughing
Breathlessness
Persistent itch all over the body without an apparent cause or rash
General fatigue
Enlarged tonsils
Headache.
Symptoms of Advanced Lymphoma
More advanced lymphoma may present with the following symptoms:

In certain instances, people feel pain in the lymph nodes after drinking alcohol.
If the lymphoma involves lymphatic tissue within the abdomen, bowel or stomach, fluid may build up causing swelling near the intestines, potentially leading to sensations of abdominal pressure, pain, diarrhea and/or indigestion.
The enlarged lymph node sometimes causes other symptoms by pressing against a vein (causing swelling of an arm or leg), or against a nerve (causing pain, numbness, or tingling in an arm or leg).
Some people experience lower back pain that is unexplained. It is thought that this may be caused by expanding lymph nodes pressing on nerves.
As lymphomas progress and cancerous lymphocytes spread beyond the lymphatic system, the body loses its ability to fight infection. The generalized symptoms that develop may be confused with signs of influenza, tuberculosis, other infections such as infectious mononucleosis or other cancers.

Lymphoma Cancer ,Risk Factors

Lymphoma Cancer

Lymphomas are an uncommon group of malignancies that are often quite sensitive to treatment. Depending on the extent of the disease and the type of lymphoma, a hopeful outcome is often expected.

Lymphomas are malignancies of the lymphatic system; they are categorized as being Hodgkin or Non-Hodgkin in variety. There are many Non- Hodgkin lymphoma types and these are categorized as either being low, intermediate or high grade. Lymphomas of higher grade act more aggressively. Treatment depends on the type and stage of the disease.

Most lymphomas are treated with intravenous chemotherapy. Radiation therapy may be added after chemotherapy to "consolidate" the treatment – to help maximize local control. For early disease, radiation can be used definitively, without chemotherapy.

Risk Factors

For most lymphomas, patients have no known risk factor. Known risk factors:

Immunosuppression – i.e. HIV
Epstein Bar Virus
Helicobacter Pylori (bacteria that causes stomach ulcers)
Human T-cell Leukemia/Lymphoma virus type-1
Hepatitis C virus

Symptoms

High fevers, weight loss, and night sweats are classic symptoms of lymphoma. Lymphoma may be diagnosed after testing has been completed on swollen lymph nodes or abnormal growths. Lymph node swelling can cause local symptoms including pressure on adjacent tissues and organs.

Diagnosis

Biopsy is necessary to prove the diagnosis of lymphoma. Often an enlarged lymph node is biopsied.

Staging

Tests are performed to evaluate the extent of the disease, meaning how far it has spread. Staging exams utilized in the management of lymphoma include bone marrow biopsy, a CT scan of chest/Abdomen/Pelvis, and PET/CT scan.

What is Lymphoma ?





What is Lymphoma

Lymphoma is simply defined as a type of cancer in the lymph system. British physician Thomas Hodgkin was the first to publish initial descriptions of the condition in 1832. Thus, the specific type of lymphoma he described (Hodgkin’s lymphoma) was appropriately named after him. After his initial description, many other studies looked at several other forms or types of the cancerous disease.


cancer appears when several of our bodies’ cells begin behaving abnormally. The body is comprised of various kinds of cells found in different organs like the nerves of blood. At times, normal cells cease getting usual biological signals that make them stop growing. When that happens, the cells abnormally continue to multiply and grow. This is the formation of cancer cells. When the cancer cells grow, the affected organ stops working normally. Several of the cancer cells also start to break off from the original site, spreading into many other body parts and affecting many other organs.
The lymph system comprises an interconnected network with thin nodes and tubes carrying white blood cells. Such cells are responsible for fighting off infections. This way, they are vitally significant to the body’s overall well-being. When a lymphocyte (a specific kind of white blood cell) in the lymph system starts to become cancerous, it would tend to multiply and grow leading to formation of lymphoma.

Which part of the body is usually affected by lymphoma? The cancer could affect any part of the lymph system. Usually, patients initially notice abnormal enlargement of the lymph nodes, specifically in the areas of the groin, the neck, and the armpits. However, lymphoma could also manifest in several other organs of the body. This is because minimal amounts of lymph tissue pass into practically every organ in the body as white blood cells reach out to different areas to perform control of infections.
This type of cancer is currently the most usual form of blood cancer or hematological malignancy especially in the developed countries. Lymphoma comprises about 5.3% of overall forms of cancers in the United States alone. It comprises of up to 55.6% of blood cancers diagnosed. According to data released by the US National Institute of Health, Hodgkin’s lymphoma is accounting for about 1% of total cases of cancer across the country. Patients with HIV infection and exposure to certain medications and drugs have higher incidences of lymphoma for obvious reasons.
Many forms of lymphoma are indolent (occurring lifelong even without medication or treatment) or aggressive (causing fast deterioration of health and eventually death). However, most incidences of aggressive lymphomas are responding ideally to treatment. In other words, they are curable. This condition is not a single type of cancer because it comprises of a group of several related forms of cancers. There are about 30 various types of identified lymphoma. In a broad sense, lymphoma could be categorized as either Hodgkin or Non-Hodgkin lymphoma. Of course, each type has its own features and manifestations and results to different outcomes in the long term.
