Non-Hodgkin’s Lymphoma
Non-Hodgkin’s Lymphoma or NHL is the cancer affecting the lymph nodes that constitute the lymphatic system. The lymphatic system dons crucial role in the immune system and is present all through the body. NHL leads to the cells present in the lymphatic system growing uninhibitedly or the cells fail to have normal fatality as that of the other normal cells.
NHL is non-communicable and is not the outcome of any injury. In case of slow-proliferating lymphoma, long-standing survival rates are prevalent, however they cannot be treated. The more belligerent forms of tumors are more lethal, though a long-standing cure is doable. The kind, its outcome and its rate of proliferation ascertain the ideal course of its treatment.
The prevalent forms of NHL are:
- The generally, slow-spreading follicular lymphoma.
- The prevalent, increasingly belligerent diffuse large B-cell lymphoma.
The less prevalent forms of NHL are:
- Mantle cell lymphoma
- Small lymphocytic lymphoma
- Burkitt’s lymphoma.
Causes of NHL:
- The causes leading to non-Hodgkin’s lymphoma are unclear with surmounting cases of NHL surfacing. Anomalous cell proliferation generally happens as a consequence of NHL that could be elicited due to some reasons like an infection or being exposed to some environmental substance.
- Lymphomas are the consequence of particular blood cells known as lymphocytes which burgeon and repudiate adhering to regular signals – particularly the orders to have a normal death. There is eventual accumulation of lymphocytes in the lymph nodes and could lead to grave conditions due to their size and their inefficacy in combating infections, that is their routine task.
Symptoms of NHL:
The symptoms of NHL are dependent on which part of the body the ailment has affected. The widespread symptom is a swell up of the lymph nodes present in the regions of the neck, armpits or groin that cause no pain. Other signs comprise of:
- Inexplicable fever.
- Night sweating.
- Intense exhaustion.
- Inexplicable weight reduction.
- Scratchy skin.
- Reddish blotches on the skin.
- Coughing or succinctness in breathing.
- Abdominal or back pain.
Risk Factors:
As the risk factors leading to NHL are still unclear the below mentioned might raise the likelihood of developing the condition. However, many individuals having these risk factors are never detected with NHL, and there are several others who in spite of not having any of these risk factors do have NHL.
- Male gender
NHL is prevalent among males as compared to females. - Age
The probability of contracting NHL rises in accordance with age. - Impeded Immune system
NHL is prevalent amongst those having an impeded immune system such as autoimmune diseases, HIV or AIDS. It is additionally prevalent in those individuals having immunosuppressant drugs like medications subsequent to an organ transplantation surgery. - Having a viral or bacterial infection
Being infected with the virus like Epstein-Barr or with the bacteria Heliobacter pylori raises the chances of developing NHL. The Heliobacter pylori induced infection could involve the stomach. - Being exposed to certain elements in the environment
Being exposed to fertilizers or insect repellents meant for farming purposes, solvents, other kinds of chemicals, asbestos, arsenic, other types of chemicals could raise the chances of getting NHL.
Diagnosis & Tests:
- In case NHL has been doubted, then the doctor would carry out a comprehensive physical exam of the patient and inquire about the medical history. The physical exam comprises of looking out for enlargement in the lymph nodes in the neck, arm pits and groin.
- A biopsy procedure is conducted wherein a sample of tissue is drawn from the lymph node, though the other tissues could also be taken for analysis purposes.
- A bone marrow aspiration and biopsy also known as bone marrow biopsy would be carried out for finding whether the lymph nodes are found in the bone marrow. In bone marrow aspiration, a miniscule quantity of fluid and cells from the bone marrow are withdrawn with the assistance of a fine needle inserted into a bone. A bone marrow biopsy involves the removal of the bone along with the marrow present in it for microscopic evaluation. Generally, aspiration is generally performed initially followed by biopsy.
The doctor could additionally advice to undergo other kinds of tests which comprise of:
- Blood analysis like a chemistry screen for the measurement of the quantities of numerous substances present in the blood and a CBC (complete blood count) for getting data on the types and number of cells present in the blood.
- An X-ray done of the chest region for capturing imagery of the internal organs inclusive of the heart and lungs, the blood vessels and the diaphragm (the fine muscle sheet) separating the chest from the abdomen.
- A CAT or CT scan (computed tomography) or MRI (magnetic resonance imaging) for getting explicit images of the internal organs of the chest, abdominal and pelvic region.
- A positron emission tomography or PET for viewing locations of enhanced metabolic activities for instance the varied chemical activities in the body like sugars being utilised for producing energy. Metabolic activity is usually observed to be elevated in case of cancerous cells.
- Flow cytometry that analyses the kinds of cells present in the tissue sample taken during biopsy. Such test aids in detecting the kind of lymphoma.
- Spinal Tap or Lumbar puncture for checking if there is presence of lymphoma cells in the CSF (cerebrospinal fluid) that encases the brain and the spinal cord.
- MUGA scan – Multigated acquisition scan is a form of cardiac blood pool scan that offers information about how ably the heart is delivering blood to the other areas of the body. A MUGA scan could reveal if the heart could endure particular forms of chemotherapy such as doxorubicin.
Early Diagnosis
Presently, there are no specialised tests suggested for early diagnosis of non-Hodgkin’s lymphoma. However, the ideal approach for early diagnosis is visiting the doctor when one starts developing signs of NHL.
