There was a recent study released about the effect of cannabis on males under age 35. The results? The risk of testicular cancer doubles. Why? I dunno. I stopped recreational use of it over 25 years ago. (when I became a Dad). I never presented with symptoms that made me consider it as a treatment or treatment supplement, but I have no bias for or against. Just thought, in case someone (esp. males <35) is considering it, that this info needed to be shared.
Here is a study from 2009 showing an increase in Testicular Cancer with Marijuana use.
Testicular Cancer and Marijuana
A couple of things make this study of interest.
1. The increased Cancer rates were specifically found with Nonseminoma and Mixed Histology types of Testicular Cancer.
1a. Cigarette smoking also causes an increase in Cancer rates (including Testicular Cancer). Check out the increased risk for smoking cigarettes
HERE. Could this increased risk in Marijuana use differ by mode of ingestion? For example, is there a lower risk of Vaporizer use or oral ingestion versus Smoking? I would also be interested if there is a higher risk in persons who smoke rolled Marijuana cigarettes "joints" versus those who smoke a Water Pipe (Bong).
1b. The increased Cancer rates were specifically found with Nonseminoma and Mixed Histology types of Testicular Cancer. These types of Testicular Cancer have a poorer prognosis than Seminoma Testicular Cancer
(ref).
Are men who are facing a more difficult prognosis more apt to report anything and everything that they have come into contact with that is a potential cancer causing agent? It is natural to think about current and past exposures regarding their role in a cancer diagnosis. Healthy men, when asked the "have you ever smoked marijuana" question are less likely to report an uneventful marijuana smoking experience from the distant past than men who have been wracking their brain over past exposures.
However, this idea does not explain the increase in Nonseminoma and Mixed Histology Testicular Cancers over Seminoma types.
2. Marijuana exerts a significant Immune System "quieting" effect. Although this can be helpful in patients using Medicinal Marijuana for Inflammatory reduction, an Immune Suppressant medication does increase the risk of certain types of Cancer. As a general rule, an Immunosuppressant increases Cancer risk. Some Immunosuppressants carry a greater risk than others.
Other Immunosuppressants that increase Cancer Risk (the increase in cancer risk varies by dosage and drug type):
[wiki]Prednisone[/wiki]
[wiki]Remicade[/wiki]
[wiki]Imuran[/wiki]
[wiki]6-MP[/wiki]
I do not aim to deter anyone from therapy using Immunosuppressant medication. But, knowing your increased risk, and what type of cancer typically presents with each drug, should be combined with a vigilant approach to cancer screening. As with any new lump or bump - bring it to the attention of your doctor. Cancer caught in the early stages have a much higher cure rate than those diagnosed later.
