Causes and Risk Factors for Hodgkin Lymphoma
Hodgkin lymphoma is a type of cancer that originates in the lymphatic system, which is a part of the body's immune system. It primarily affects B lymphocytes, a type of white blood cell that produces antibodies to help fight infections.
Changes in the DNA of lymphocytes can cause them to replicate uncontrollably, leading to Hodgkin lymphoma. The exact cause of Hodgkin lymphoma is unknown, but there are some factors that may contribute to its development. Genetics and environmental factors are thought to contribute to the development of Hodgkin lymphoma. Certain genes, such as SGK1, DUSP2, and JUNB, may play a role in the development of Hodgkin lymphoma. Environmental factors, such as viral infections, may also play a role.
It's important to note that more research is needed to fully understand why some people develop Hodgkin lymphoma while others do not.
People with the following non-modifiable risk factors for Hodgkin lymphoma have a high risk of developing the disease, compared to people who do not have the factor:
- Age: People in their 20s and 30s, or over age 65 years.
- Sex: People assigned male at birth.
- Genetics:
- Family history (parent, child or sibling) of Hodgkin lymphoma can increase the risk.
- Certain genes, such as SGK1, DUSP2, and JUNB.
- Immunosuppression: A weakened immune system, such as from medications, organ transplant, or an autoimmune condition.
- Certain viral infections:
- Past infection with Epstein-Barr virus (EBV): EBV is a virus that causes mononucleosis. Infection with EBV may lead to changes in DNA and the development of Hodgkin lymphoma cancer cells.
- HIV infection.
It's important to note that having these risk factors doesn't mean a person will definitely develop Hodgkin lymphoma. They simply indicate a higher likelihood of developing the condition.
In general, Hodgkin lymphoma is considered to not be preventable.
Because HIV infection may increase the risk of developing Hodgkin lymphoma, preventing HIV infection may possibly reduce a person’s risk. Reducing the risk of HIV infection includes:
- Practicing safe sex: Limiting unprotected sexual activity can help lower the risk of infection with HIV.
- Limiting intravenous drug use: Avoiding or reducing the use of intravenous drugs can lower the risk of HIV infection.
People with risk factors for Hodgkin lymphoma can work with their healthcare professionals to get regular check-ups and maintain a healthy immune system.
It's important to note that these actions are general recommendations and may not guarantee complete prevention. It's always a good idea to consult with a healthcare provider for personalized advice and guidance on reducing individual risk factors.
