Jake “The Snake” Roberts underwent emergency surgery today to remove a lump on the back of his knee which doctors diagnosed as skin cancer.

The soon-to-be WWE Hall of Famer said he is scared in a video posted by his friend Diamond Dallas Page yesterday and said that whenever you hear the word cancer it shakes you up and he would be lying if he said he’s not scared.

He said doctors don’t know yet how bad it is and they will take some layers of flash from underneath it because the lump has “little fingers” growing out of it and going into his muscle tissue.

In a message on Twitter a few hours ago, Roberts said that the surgery went well but won’t know if the growth is all removed or spread until tests come back. “Doc optimistic and so am I,” he said.
