Some factors that may increase a man’s risk of testicular cancer include:
Undescended testicle (when an infant)
Family history (having a father or brother who has had testicular cancer).
There is no known link between testicular cancer and injury to the testicles, sporting strains, hot baths or wearing tight clothes.
Researchers are learning how certain changes in a cell’s DNA can cause the cell to become cancerous. DNA is the chemical in each of our cells that makes up our genes. Genes tell our cells how to function. They are packaged in chromosomes, which are long strands of DNA in each cell. Scientists are studying DNA and chromosome changes to learn more about which genes are affected and how this might lead to testicular cancer.
