Wrestling legend Bret "Hitman" Hart says he's undergoing surgery for prostate cancer -- but vows to defeat "this nemesis once and for all."

The 58-year-old made the announcement on Instagram -- saying, "I beat the odds when I suffered my stroke in 2002, but it is now yet again, that I ... stand unafraid and face the tough road ahead of me."

He continued, "I will wage my fearsome fight against cancer with one shield and one sword carrying my determination and my fury for life, emboldened by all the love that's kept me going this long already."

"My children, grandchildren, and my loving wife Steph have been and will constantly be at my side. I refuse to lose, I will never give in or give up, and I will win this battle or die trying."

Looks like it's chest day for Rob Kardashian.

His chick, Blac Chyna, documented his bench press reps -- although she conveniently kept the bar and the weights out of frame.

We don't know how much Rob's lifting, but we can say his arms are looking fit.

The Roots cut a former member out of his share of the band's success after cancer forced him to quit ... at least that's his claim in the lawsuit he's just filed.

Ex-bass player, Leonard "Hub" Hubbard, started in the Philly band in 1992 -- before they were even called The Roots ... and played with them until 2007, when he was diagnosed with multiple myeloma ... a form of blood cancer. The illness forced him to leave the band, 2 years before they started backing Jimmy Fallon on late night TV.

Hub says his deal with the band called for him to continue getting paid as a co-owner. But in his lawsuit, Hub says a former manager for the group sent him a letter in 2014 threatening he was going to lose his health insurance and his cut of the band's revenues.

He says other band members continue to get a bigger share of the pie than they deserve ... while he's left out in the cold. Hub is suing founding members Questlove and Black Thought and their current manager.

We've reached out to Questlove ... no word back yet.

Now, Lacy's people have confirmed the two sides have touched base in the hopes of working something out ... though no agreement has been struck yet.

Horton says he doesn't want to undermine Green Bay's training plan for Lacy -- but instead, he wants to work WITH the team to get Eddie where he needs to be.

"The Packers will get him ready for the season. My job will be to get the weight off and help him eat better."

Mayor Karen Weaver is rolling out a welcome mat for celebs to join water relief efforts in Flint, Michigan -- and her wish list sounds like a Hall of Fame roster!
