This comes after Diamond, known for his character Screech from the show from when he was 10-years-old to when he was 23-years-old, was hospitalized earlier in January. A message on his Facebook page read, âAt this time we can confirm that Dustin does have cancer. Dustin Will disclose more information once it is available and a plan moving forward is made." At the time, several of his fans and co-stars wished him well on social media. However, after his death, tributes have poured in for him. Mario Lopez on Instagram said, âDustin, you will be missed my man. The fragility of this life is something never to be taken for granted. Prayers for your family will continue on..." Later, during the February 1 episode of Access Hollywood, Lopez added: âHe was like a little brother to me. We always remained in contact over the years, and I actually just spoke with him a couple of weeks ago after he got his diagnosis. Even then, he was full of energy, and he was optimistic.â
