In a report in the journal Cancer, a study at the University of Southern California has revealed that the use of marijuana, a drug that is also used in cancer therapy, may provoke the development of testicular cancer cells.
Victoria Cortessis, assistant professor of preventive medicine at the Keck School of Medicine of USC in Los Angeles, and her colleagues looked at the self-reported history of recreational drug use in 163 young men diagnosed with testicular cancer.
They then compared those findings with 292 healthy men of the same age and ethnicity.
Marijuana appeared to cause two subtypes of testicular cancer in the marijuana-smoking men.
The (USC) findings suggest the potential cancer-causing effects of marijuana on testicular cells should be considered not only in personal decisions regarding recreational drug use, but also when marijuana and its derivatives are used for therapeutic purposes in young male patients.
