A 45-year-old male asked:

what causes testicular cancer?

Abnormal cells: Abnormal cells in testis multiply and become tumors. They are relatively uncommon tumors. But all men should prectice scrotal self examination on a regular basis (say x1/month), ideally in the shower. Seek medical help if you feel a hard lump, or one testicle starts to grow much larger than ihe other one. Intraabdominal undescended testes are at cancer risk even after correction. Prognosis is good.

Not known: We do not have a clear understanding of what causes testicular cancer. We do know that, in general, it is a disease of younger men (generally age 30 or less).

Dumb luck: Apart from cryptorchidism, which greatly increases the risk, these seem to strike at random. There are two studies you may see that to me reek of bad science. In one, the men who had testicular cancer and wonder why were more willing to confess to having tried cannabis. In the other, men who'd lost a testis exaggerated their past athletic achievements. No, fitness doesn't cause cancer.

No: That's one more scare story by somebody who doesn't understand the difference between the natural radiation that electronic devices and everything else produce, and the ionizing radiation that causes cancer. A bad epidemiologic study can "show" anything based on recall bias. Enjoy today's technology without this fear.

A mass: Almost without exception, testicular cancer announces itself as a mass in the testis. Usually it's palpable as a lump on or within the testis; it may be deep and the testis simply larger.

Could exposure to dioxin cause testicular cancer?

I say no: Probably no chemical exposure has been more deeply studied than that of vietnam vets and i could find nothing in the nih database to support this; there was a small increase reported in gulf war vets. Claims that testicular cancer results from too much / too little exercise or cannabis seem soft to me. Unless it's from cryptorchidism, don't look for a cause.

Here are some ...: This is a good Q. Known to us, each life event always represents itself as a process of lifelong making from compiling multiple factors in the past. Electromagnetic energy has some effect to tissue and has existed everywhere we go among modern society and environments; we've nowhere to escape. But, if any, the amount of such inevitable leaking roaming energy is not clinically significant.Best wish

Can soiled or sweated underwear be cause of testicular cancer?

No: You're a young man and if your underwear didn't get sweaty, I'd urge you to go out and exercise more. Getting your underclothes dirty simply isn't a sign of testicular cancer. Practice good hygiene and check yourself -- most of us handle ourselves often and simply be aware that a new mass in the scrotum needs to be seen. Best wishes.
