Possible risk factors
Unlike many cancers, there are few known strong risk factors for testicular cancer (unlike the link between smoking and lung cancer). Some risk factors can be traced to minority cases:
- Undescended testicle – where the testicle fails to descend into the scrotum. The testicles of a male baby form in its abdomen whilst in the mother’s womb and normally descend into the scrotum at birth or shortly afterwards.
- Pre-cancerous cells – these cells have a 50% chance of developing into testicular cancer within 5 years of being found. They may be found during a biopsy when investigating infertility.
- If a man’s brother or father has had testicular cancer.
- A man having history of testicular cancer himself.
- Caucasian men.
- Men with HIV.
- If you are taller than the average man.
- Twins, especially if identical.
- A build-up of calcium called microlithiasis in some men with other abnormalities of the testicles.
- An inactive lifestyle.
- Repeated trauma to the testicles.
- Smoking marijuana.
