Bullshit. Testicular cancer is common in those ages because those ages are the ages that men's testicles are over-active
And produce a lot of testosterone.. Well, perhaps. But one can probably safely assume that even if the increased testicular activity is the cause, for instance if the increased spermogenesis has a role, and may contribute to the DNA damage of tubuli seminiferi, then endogenous testosterone (or some of it's compounds) may very well be a contributing factor.

I've heard reports of decreased risk of testicular cancer associated with testosterone use.
Then cite them, please. On the other hand, if this is true, then perhaps the exogenous testosterone, wich is known to suppress testicular function (many HRT users report shrinkage of testicles), may be shutting down one of the several other androgenic chemicals usually produced by testicles, wich otherwise may have been contributing to the cancer risk.

The same with women taking estrogen having a decreased risk of ovarian cancer.
Uh, hello?
Postmenopausal women who use estrogen replacement therapy (ERT) for more than 10 years may be have twice the risk of dying from ovarian cancer as their peers who did not take ERT.

The testes become dormant when their function is suppressed (from using testosterone shots, for example) resulting in a decrease in function and also decrease in cancer risk.
This, however, may be a plausible explanation, and merits further research. However, I still believe testosterone, like estrogen, has a role in the process.

Also, to clear up another myth, testosterone boosts the immune system. It's one benefit AIDS sufferers have from testosterone therapy.
This is absolute non-sense. All of the major studies on animals as well as evolutionary theories and epidemiological observations are in firm agreement that males, under the influence of male hormones, suffer from a weaker immune system, and are susceptible to more parasites and diseases.
In addition to the link of CNN's coverage that actually suggested anti-androgen therapy for AIDS patients (an assertion that was based on laboratory research, btw), here's some more data to review:
Testosterone may impede immunity
When testosterone is removed, the immune cells come back strong and aggressive, ready to attack. Says Dr. Kwon, "They become twitchy, very reactive, and in this state they can, in fact, mediate a strong immune response -- which, as physicians, is just what we want."

The only one there is truth to is the prostate cancer. But even then, I've read studies showing the role of testosterone in prostate cancer to be minimal.
It may be minimal because the largest study on male HRT and prostate cancer ever done, was a 3 year follow up only. However, consider this recent study (2005), wich actually shows testosterone use increses the risk:
Testosterone treatment linked with prostate cancer

We have seen that studies on estrogen and ovarian cancer revealed that the cancer risk actually doubles - but only after 10 years of use. Untill this time, the risk is almost non-existant. This is how hormones work; it takes time, sometimes many years, before all of the effects set in. Individual and genetic variation further regulate and influence these changes; that's why some males never develop prostate cancer or go bald, without being hypogonadal.
Btw, as to the other effects, just because you dislike the possibility of their reality, and are unwilling to read my post, doesn't make them untrue. As I have cited, studies done both in vivo and in vitro revealed that testosterone stimulates certain parts of melanoma and laryngeal cancer cells. It's a fact - that's why men are more prone to these cancers; that's why men develop later and more malignant forms, and are more likely to die of it.
