The White House is explaining that scar on President Bush's forehead today. It turns out the president had a benign lesion removed over the weekend.

A dermatologist "froze" the lesion in a typical procedure that destroys the cells and forms a scab as the skin repairs itself.

The president has had lesions removed before, including two noncancerous moles from his left temple last year, a precancerous lesion on his left arm in 2006 and a noncancerous skin growth on his neck in 2005.

While none of the growths has been cancerous, the president has regular checkups to guard against any lesions advancing to a more dangerous stage.
