Causes and Risks

There is no single cause of testicular cancer however, the number of men who develop it is on the increase and research is being done to find out how to prevent this, but some factors seem to increase the risk of developing itLump-Unhappy

The following factors are known to increase the risk of developing testicular cancer:

Cryptorchidism (undescended testicle)

Men with a history of undescended testicles have a higher risk of testicular cancer. Normally, the testicles form in the abdomen of the foetus and descend into the scrotum before birth. Males can be born with an undescended testicle on one or both sides because of a failure of this process. The exact cause of this developmental abnormality is still unclear. Surgery to bring the testicle into the scrotum (orchiopexy) is performed if the testicle does not descend on its own, usually during the first year of life.

Family history of testicular cancer 
The brothers and sons of a male diagnosed with testicular cancer have a higher risk of developing testicular cancer themselves. Genetics may play a role in the development of testicular cancer.

History of testicular cancer

Having testicular cancer or carcinoma in situ (CIS) in one testicle increases the chances of testicular cancer developing in the other testicle.
But remember some men develop testicular cancer without any of these risk factors.
