Testicular Cancer & Cycling: Is There a Link?

Testicular Cancer & Cycling: Is There a Link?

Cyclist Ivan Basso's announcement today that he has testicular cancer comes decades after Lance Armstrong famously battled the disease. Could two cases of testicular cancer in the world's top cyclists be a coincidence, or does something approximately competitive cycling increase men's risk of the disease?

Basso said at a news conference today (July 13) that he is withdrawing from the Tour de France after being diagnosed with testicular cancer during the race, according to BBC News. Doctors found the cancer after Basso complained of pain in the area following a crash. He will now return to his native Italy to undergo surgery, the BBC said.

Like Armstrong, Basso has previously finished in the top 10 during the Tour de France. Also, like Armstrong, Basso has admitted to doping, & was banned from the sport for several years.

p> Despite these similarities, experts say that the most likely reason for the two cases is the men's age: Testicular cancer mostly affects men between ages 20 & 39, according to the National Institutes of Health. Armstrong was 25 when he was diagnosed, & Basso is 37.

"The main usual denominator is there age," said Dr. Thomas Schwaab, an associate professor of oncology at Roswell Park Cancer Institute in Buffalo, New York. "There's no link between athletic sports in general & biking in particular with regard to the incidence of testicular cancer," Schwaab said. [10 Do's & Don'ts to Reduce Your Risk of Cancer]

Although some people might think that sitting on a bike for hours at a time might have some effect on testicular cancer risk, Schwaab noted that a bicyclist's weight rests on the perineum (the area between the genitals & the anus), rather than the testes.

In addition, there's no link between the drugs used by cyclists & testicular cancer. Most of the drugs that cyclists take are aimed at increasing the amount of red blood cells in the body, rather than affecting hormone production, Schwaab said.

The satisfactory news is that testicular cancer has a very satisfactory prognosis if it's caught early. "Most testes cancers are diagnosed early enough so that timely removal of the testicle will lead to a compete cure," Schwaab said.

Even when the cancer is diagnosed in the after stages, the disease is often curable, as Armstrong's case shows, Schwaabsaid.

A 2014 study, published in the Journal of Men's Health, suggested a possible link between cycling & men’s risk of prostate cancer. But the researchers said more research is needed to know for sure whether cycling caused the men's increased cancer risk.
