Did Kevin Garnett really trash-talk Charlie Villanueva by calling him a "cancer patient?"

A couple folks have sent this along. From ESPN.com:

The Boston Celtics pounded the Detroit Pistons on Tuesday, and Charlie Villanueva posted messages on his Twitter account that indicate Kevin Garnett may have made it personal.

One of the tweets says: "KG called me a cancer patient, I'm pissed because, u know how many people died from cancer, and he's tossing it like it's a joke."

Garnett is known for his trash talking on the court. Villanueva suffers from alopecia universalis, a medical condition that results in hair loss. The Detroit forward does not have hair on his head.

The Pistons confirmed that Villanueva posted the tweets but had no further comment.

Another tweet from Villanueva says that Garnett's alleged comments hit home.

"I wouldn't even trip about that, but a cancer patient, I know way 2 many people who passed away from it, and I have a special place 4 those," the tweet reads.

Here's the link to Villanueva's Twitter page. Obviously, if KG made that comment, it's way out of line -- even in the context of talking trash.
