Overview of Non-Hodgkin's Lymphoma
Definition and Classification
Non-Hodgkin lymphoma (NHL) is a type of cancer that originates in the lymphatic system, which is crucial for the immune system. This cancer can develop in various parts of the body, including lymph nodes, spleen, and bone marrow. There are over 60 subtypes of NHL, primarily classified into B-cell and T-cell lymphomas. B-cell lymphomas account for about 85% of cases, while T-cell lymphomas are less common but often more challenging to treat.
Prevalence and Incidence
In the United States, approximately 70,000 new cases of non-Hodgkin lymphoma are diagnosed each year. The incidence of NHL has been rising, particularly among older adults. The following table summarizes the estimated incidence rates by age group:
Comparison with Hodgkin's Lymphoma
Unlike Hodgkin lymphoma, which has a distinct set of characteristics and a better prognosis, non-Hodgkin lymphoma presents a wider variety of symptoms and outcomes. Understanding these differences is essential for effective diagnosis and treatment. While both types affect the lymphatic system, NHL is more common and can be more aggressive, depending on the subtype.
Causes and Risk Factors of Non-Hodgkin's Lymphoma
Genetic Mutations
Non-Hodgkin's lymphoma (NHL) can arise from genetic mutations in lymphocytes, the white blood cells that play a crucial role in the immune system. These mutations can lead to uncontrolled cell growth, resulting in cancer. While the exact cause of these mutations is often unclear, certain inherited conditions may increase the risk of developing NHL.
Environmental Exposures
Exposure to certain environmental factors can also elevate the risk of NHL. For instance, individuals who work with pesticides or other chemicals may have a higher likelihood of developing this type of cancer. Research indicates that agricultural workers exposed to high levels of pesticides are particularly at risk. Additionally, infections from viruses such as HIV and Epstein-Barr have been linked to an increased risk of NHL.
Medical Conditions and Treatments
Certain medical conditions can predispose individuals to NHL. Autoimmune diseases, such as rheumatoid arthritis and lupus, have been associated with a higher risk. Moreover, individuals who have undergone treatments that suppress the immune system, such as organ transplants or chemotherapy for other cancers, may also be at increased risk. For example, patients who have received radiation therapy for previous cancers may develop NHL later in life.
In summary, while the exact causes of non-Hodgkin's lymphoma remain complex and multifactorial, understanding these risk factors can aid in early detection and prevention strategies.
Symptoms and Early Signs of Non-Hodgkin's Lymphoma
Common Symptoms
Non-Hodgkin's lymphoma (NHL) can show various signs and symptoms that depend on the type and location of the lymphoma in the body. One of the most noticeable signs is painless swelling of lymph nodes, which can often be felt in areas like the neck, armpits, or groin. Other common symptoms include unexplained fever, excessive sweating—especially at night—and loss of appetite. These symptoms can sometimes be mistaken for other illnesses, so it is important to consult a healthcare provider if they occur.
Symptoms by Lymphoma Type
Different types of non-Hodgkin's lymphoma may present unique symptoms. For instance, lymphomas affecting the abdomen can lead to abdominal pain or swelling, while those in the chest may cause coughing or difficulty breathing.

B-Cell Lymphomas
B-cell lymphomas include several types:
Follicular lymphoma is the most common type of indolent non-Hodgkin lymphoma. It grows slowly and typically forms in lymph nodes.
Diffuse large B-cell lymphoma (DLBCL) is a fast-growing type and accounts for approximately 30% of all NHL cases. It can start in lymph nodes or other body parts.
Small lymphocytic lymphoma is similar to chronic lymphocytic leukemia and grows slowly.
Mantle cell lymphoma arises from B cells in the mantle zone of lymph nodes and is considered aggressive.
T-Cell Lymphomas
T-cell lymphomas are generally less common and harder to treat. They include:
Peripheral T-cell lymphoma, which often presents as enlarged lymph nodes in various body areas.
Precursor T-lymphoblastic lymphoma, which starts in immature T-cells.
Cutaneous T-cell lymphoma, primarily affecting the skin and can manifest as red, scaly patches.
