The reality TV star went under the knife on Friday after doctors biopsied a suspicious mark on his face and determined it to be cancerous, according to TMZ.
Surgery: Olympic athlete Bruce Jenner revealed a fresh scar on the side of his face as he watched Lamar Odom play with the Dallas Mavericks at the Staples Center last night
Cheering him on: He was joined by wife Kris Jenner who watched the Los Angeles Lakers defeat the Mavericks by a final score of 73-70 at the Staples CenterA large chunk of his right cheek was removed and he has been ordered to stay out of the sun.
Of course, Jenner has had surgery on his face before - but usually on a voluntary basis.
He most recently had a facelift in 2009 to correct previous cosmetic work he'd had done during the 1980s.
Bruce was joined at the basketball by his wife Kris Jenner and stepdaughter Khloe Kardashian, who all watched the Laker's beat the Mavericks 73-70.
Quick recovery: Bruce is said to have had surgery on Friday
Looking away: Kris looked more interested in the scantily-clad cheerleaders than her husband
He received a standing ovation as he returned to the Staples Center for the first time since he was traded away to the Mavericks.
Khloe was in good spirits during the game, despite rumours that Odom, who she has been married to for two years - enjoyed a wild time at a notorious Washington D.C. strip club.
According to RadarOnline.com, the forward spent hundreds of dollars on strippers according to one eyewitness who spoke to the website.
They said at one point Lamar was seen sprawled out in a dimly lit corner of the Stadium Club strip club, which bills itself as a five star dining and premier gentleman's club experience, and was joined by Mavericks teammates Shawn Marion and Delonte West.
And if that wasn't all Khloe had to deal with, she also found out last week that the man she thought was her father may not be.
Her mother Kris apparently wrote in her latest book that she had an affair that led to her divorce from Robert Kardshian.
But she didn't reveal how long the affair lasted which raised questions over whether her lover is Khloe's father.
