CircleDNA's Premium Test includes personalised reports on Lymphoma risk. See your cancer genetic risk →
Lymphoma is a cancer of the lymphatic system. First-degree relatives of lymphoma patients have a 2–3 times higher risk of developing the disease.
How Genetic Is Lymphoma?
Genetics plays a meaningful role in Lymphoma, with heritability estimated at around 20%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Lymphoma: BCL2,MYC,BRCA2. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Lymphoma?
Family history does matter. Having close relatives with Lymphoma can increase your personal risk, though it is not deterministic. Maintaining a healthy lifestyle and regular screening remain important regardless of family background.
