In a classic case of putting your money where your mouth is, new UFC signee Brock Lesnar - who has made no bones about wanting to fight the best the heavyweight division has to offer - will make his Octagon debut at UFC 81 on February 2nd against none other than former UFC Heavyweight Champion Frank Mir.

The bout will be held at the Mandalay Bay Events Center in Las Vegas, Nevada on the eve of Super Bowl XLII.



"It's an interesting matchup," said UFC President Dana White. "Lesnar is a great wrestler, a good athlete, and this is definitely gonna be a big test for him. Frank Mir is a former world champion who is coming off a big win over Antoni Hardonk, and he's looking to get his career back on track while Lesnar's looking to walk into the UFC and prove what type of fighter he's gonna be by trying to knock him off."

LONDON (Reuters) - Natural levels of a man's testosterone do not affect his prostate cancer risk as some had thought, a finding that should spur scientists to rethink their approach to the disease, researchers said on Tuesday.

Nearly two dozen studies have examined a potential link between testosterone and prostate cancer risk but so far results have been inconclusive, said Andrew Roddam, an epidemiologist at the University of Oxford who led the study.

Writing in the Journal of the National Cancer Institute, Roddam and colleagues said they found no such relationship after collecting worldwide data on hormone levels of 3,886 men who eventually developed prostate cancer and 6,438 men who did not.

Prostate cancer, which usually occurs in older men, is the second most common cause of cancer death among men after lung cancer. The prostate is a walnut-sized gland that makes fluid for semen.

"We looked at blood samples of men before they had cancer and men who didn't develop cancer to see if their hormone levels were different," Roddam said in a telephone interview.
