Nick Cannon Hits The Club ... After Giant Cyst Removed From Face

Nick Cannon refused to let minor surgery on his face keep him from the party scene -- 'cause the host/rapper/actor/producer hit the clubs this weekend after doctors removed a massive cyst from his cheek.

Cannon had been tweeting about the growth for the past couple of days -- explaining how he went to a skin doctor last week to treat a "cyst on my face the size of a grape!!"

The "America's Got Talent" host says doctors decided to remove the cyst but it wasn't pretty -- "I want to show y’all the pics of the removal but its too disgusting! #weakstomach."

But after the procedure, Cannon threw a band-aid on his face and hit up Hyde in Hollywood -- telling us he refuses to let the whole thing slow him down.

Nick told us doctors had to take a culture of the cyst for further examination -- but he's confident it's all good.
