What causes follicular lymphoma

According to the NCCN Guidelines for Patients with Follicular Lymphoma (2024), there's an important genetic/familial component to consider:

1. Family History Factor:

• The NCCN emphasizes that some cancers can run in families
• Healthcare providers specifically collect detailed family health histories from both sides of your family, including:
  • History of cancer
  • Age at diagnosis
  • Specific cancer types
  • Whether genetic testing was done
  • Other health conditions like heart disease and diabetes

According to the National Cancer Institute (NCI):

• Follicular lymphoma develops when B lymphocytes (a type of white blood cell) become abnormal
• Most cases have a specific genetic change called a translocation between chromosomes 14 and 18
• However, this genetic change alone is not enough to cause lymphoma, as other factors are involved

The American Cancer Society adds that while we know some risk factors, the exact cause often remains unclear. Risk factors include:

• Age (typically occurs in older adults)
• Exposure to certain chemicals
• Immune system problems
• Some infections

Important note: While we understand some risk factors, it's essential to remember that:

1. Having risk factors doesn't mean you'll definitely develop follicular lymphoma
2. Many people who develop follicular lymphoma have no obvious risk factors
3. You should discuss your specific case with your healthcare team for personalized information
