LOS ANGELES, Sept. 11 (UPI) -- Recreational marijuana use was linked to an increased risk of subtypes of testicular cancer that tend to carry a worse prognosis, U.S. researchers say.
Victoria Cortessis, assistant professor of preventive medicine at the Keck School of Medicine of the University of Southern California in Los Angeles, and colleagues looked at the self-reported history of recreational drug use in 163 young men diagnosed with testicular cancer and compared it with that of 292 healthy men of the same age and race/ethnicity.
