The Doping Science Behind the Lance Armstrong SagaWhat are those and what do they do to the body. Armstrong admits to using EPO, blood transfusions, testosterone and corticosteroids. Testosterone Enanthate is a long. Testosterone inhibits gonadotropin secretion from the pituitary gland and. Disgraced cyclist Lance Armstrong says tren ace veins used an array of performance enhancing drugs.
Doping Linked to Testicular Cancer?

I believe what the Sports Digest article says about doping. Doping is part of the pro cycling culture, same as Pro Wresting. I cannot watch the Tour without realizing the doping throughout. It's best to accept that fact and enjoy the competition.
I think all this hand-wringing over doping is just sideline gossip that many fans enjoy as much as the races. It is human nature to risk one's life for victory.

It seems likely that the preferred or undetectable drugs would change over time.
I looked up the stats for the incidence of testicular cancer: What are the key statistics about testicular cancer? Not saying there's not a connection, but I don't think two guys that we know of in 20 years is a smoking gun either.
Doping Part of Professional Cycling? Again, it initially sounds suspicious, and I wouldn't bet against it, but at this point the connection would be tenuous. Blows your hair back. When Armstrong was diagnosed, the initial reaction from his doping doc was that it was caused by the dope. I have not seen any reason to suspect that testicular cancer in the pro peloton is related to doping, or occurs at a higher incidence rate than in the comparable male population.
Like other cancers it has been widely studied, and there are no known external risk factors that lead to an increased risk. A causal connection with any cancer and environmental exposure is very difficult to demonstrate. With lung cancer, it was quite difficult, but since smoking is legal and at the time socially acceptable and very common, and lung cancer is a common cancer, the preponderance of evidence was compelling.
Use of testosterone or other steroids is definitely suspect. I would be surprised if it didn't increase the incidence of various cancers. But establishing definitive causation is another story. In Lance Armstrong's case, it seems like a particularly idiotic thing for him to do.

He was the doctor who supervised LA's doping. He knows drugs and he knows what they can do to the human body. I think his reaction was more legit than anything.
Lance had a testicle removed so would he have had less testosterone than normal? I've never heard of him having a TUE for hormone replacement. Just wondering, as sometimes he looked a bit more muscular than most stage racers. A rational assessment, based on what's known, from City of Hope here. Specifically for testicular cancer, any association with doping practices in cycling is pure speculation. That said, there's rational reason for the hypothesis.

An article out today addressing the question of a relationship with cycling broadly, citing Dr. Thomas Schwaab, an associate professor of oncology at Roswell Park Cancer Institute in Buffalo, New York, who basically suggests there is no known link. If you want to find a link to PEDs and testicular cancer look to creatine, and possibly androstenedione. There is a pretty clear link between cancers and the common doping regimens Epo, HGH so it seems plausible that the risk of testicular cancer would also be increased.
The professional doping club is probably too small to ever come up with a statistically significant test, but maybe more people will dope in the future and we'll get a chance to find out Anthony "Cycling and ethical bankruptcy have always gone together. If doping increases testicular cancer, then a shitload of male pro athletes should be getting it! Originally Posted by BacDoc. Similar Threads Ivan Basso out of Tour due to testicular cancer.

Certainly suspicion is warranted, but nothing born out in epidemiology. Join Date Jul Posts 19, Originally Posted by ibericb reactions, like opinions, are often misleading. I have no idea what that means. He may be the most knowledgeable MD in doping and human performance in the world, and as "legit" as you may feel his reaction to be, doesn't mean it's valid.
I'd ask him to show the data to support a reasonable conclusion that there is a cause and effect relationship between what Armstrong used and testicular cancer. In my career I launched and sponsored a number of cancer "hot spot" investigations and studies, and I can assure you establishing meaningful causation above appropriate general population levels is not simple or trivial. As noted separately, there is certainly reason to have concern, and to suspect that there could be a relationship given the agents commonly used for doping in cycling, but nothing beyond that even now, years later.

As several other posters have pointed out, obtaining the data for it is essentially hopeless and thus this discussion is essentially moot in the first place.

You bet they are hard to establish Years ago when I was doing worker safety and health advocacy I worked on a project trying to get testicular cancer a job related illness for LEOs. Hand held radar units were very common and LEOs rested them on their laps. We tried with a host of cancers in firefighters cases Smoldering furniture and carpet is pretty toxic stuff.
But we were unsuccessful in all cases in convincing courts of causation. And our experts were every bit as good as their experts. Maybe that landscape has changed over the years, I'm not sure, but convincing folks of cause is steep climb.
