The most common solid tumour in young men. Heritability ~49%. Affected brothers increase relative risk ~8–10 fold.
How Genetic Is Testicular Cancer?
Testicular Cancer involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 49%, though no single gene determines outcome on its own.
Key genes associated with Testicular Cancer: KITLG SPRY4 BAK1. 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 Testicular Cancer?
Family history can be informative for Testicular Cancer, but its predictive power is limited because many genes — each with small effects — combine with environmental influences. A family history of the condition may prompt earlier or more frequent screening.
