Researchers also found that men who smoked marijuana are doubling their risk of testicular tumors compared with men who passed on grass. In addition, their tumors grow at a more rapid pace than normal as well as being more resilient to fight. She also found that the use of marijuana affects their fertility and general health. As a matter of fact, Cortessis also found that the risk of testicular cancer was much greater among men who smoked less than once a week and for fewer than 10 years (2012). On the other hand, Cortessis found men who used cocaine were actually less likely to develop testicular cancer, which contradicts the use of other drugs leading to testicular cancer (2012). In conclusion, there has been a study done on the usage of marijuana and testicular cancer in 2009, so this is not happening by chance. The article states, “The National Cancer Institute estimates more than 8,500 men will be diagnosed with testicular cancer in 2012 and about 360 of them will die from it (Cortessis, 2012). Meanwhile, Cortessis brings up a point that marijuana smoke and how cannabis chemical, tetrahydrocannabinol reduces testosterone and may play be a factor with disrupting the maturity of the testes (2012). In the end, there is still a lot of research …show more content…
This is a dose response relationship for this article because of those who smoked marijuana, their risk of developing testicular tumors doubled compared to those who did not. This shows that the more a man would smoke, the higher his chances of developing testicular cancer would be. The second casual guideline is replication of findings, and that is when the association is consistent in different studies. This can be seen when an epidemiologist at the Fred Hutchinson Cancer Center in Seattle reveals that there have been three studies connecting marijuana use to testicular cancer, and no studies that contradict them. The third casual guideline that can be seen is the cessation of exposure, which states that the risk of disease should decline when exposure to the factor is reduced or eliminated. If you remove smoking marijuana than the outcome of testicular cancer will decrease. This is because testicular cancer cases are more prevalent in men younger than 35 because at that age younger men are more likely to engage in such activity. If smoking were to be eliminated, then the amount of testicular cancer would also decrease as
