In men aged 15 to 45, testicular cancer is the most common type of cancer diagnosed, and diagnosis rates are rising. Marijuana use is also rising in men within that demographic, and a new study aimed to discover whether or not there was a link between the two.
163 men living in Los Angeles, California who had been diagnosed with testicular germ cell tumors (TGCTs) between 1986 and 1991 participated in the study. Interviewers were sent to their homes to gather information relating to the participants’ personal histories, including alcohol and drug use.
According to the study, men who reported using marijuana were twice as likely to develop nonseminoma, the most severe form of testicular cancer.
“These tumors usually occur in younger men and carry a somewhat worse prognosis” than other types of testicular cancer, the study reported.
However, the research was fraught with control problems and drew only on a very small sample size. Critics point out the specious nature of the study’s other findings, including decreased nonseminoma rates in cocaine users.
