Actor Dustin Diamond, who became a teen TV icon portraying Screech on Saved by the Bell, died Monday from cancer.

Diamonds camp announced the diagnosis just three weeks earlier.

Diamonds longtime representative Roger Paul called the illness a brutal, relentless form of malignant cancer via a statement shared with HuffPost.

In that time, it managed to spread rapidly throughout his system; the only mercy it exhibited was its sharp and swift execution, Paul added. Dustin did not suffer. He did not have to lie submerged in pain. For that, we are grateful.

NBC News reports the specific cancer was stage 4 lung cancer.
