Human papillomavirus (HPV) may cause bladder cancer.

Examination of tissue samples from 117 cases of bladder cancer identified DNAAbbreviation for deoxyribonucleic acid. Composed of very long strings of nucleotides, which are abbreviated as A, C, G and T. DNA is the storage form of our genetic material. All of the instructions for the production of proteins are encoded in our DNA. from the human papillomavirus (HPV) was in 15% of the samples.  The cases associated with HPV tended to be at earlier stages and were found in patients diagnosed with cancer at a younger age.  The results strongly suggest that HPV, already a known cause of cervical, and head/neck cancer is the cause of some cases of bladder cancer.
