Beloved children's YouTuber 'Danny Go!' announces son, 14, has died after 'aggressive cancer diagnosis'

Danny Go! creator Daniel Coleman has announced that his teenage son, Isaac, has died following an aggressive cancer diagnosis. Isaac was 14 years old.

The children’s entertainer shared the news on Instagram on Friday, May 22, posting a photo of Isaac alongside a black-and-white picture of the pair together. Isaac died on Thursday, May 21, after being diagnosed with stage 3 mouth cancer.

"Isaac Daniel Coleman. 10/3/11 - 5/21/26," Coleman wrote. "Oh my sweet boy. There's so much I want to say, but I don't know how yet. I already miss you so much, and the pain in my heart is far more than I can process. But looking through thousands of pictures and videos this past week, I'm also filled with tremendous pride."

"Your 14 years were full of so many challenges, but you met them all with such grit…and you somehow kept your trademark joy in spite of it all. You truly had a spark like no other, Isaac!" he continued. "Remembering how loved you were and how full of life your time here was gives me great comfort. Being your dad was the honor of a lifetime. I'm so proud of you and I love you forever. Rest peacefully, son."

Coleman first revealed diagnosis in 2025

Coleman first told fans about Isaac’s diagnosis in December 2025, revealing that his son had cancer in his mouth linked to Fanconi anemia, a rare inherited condition that affects bone marrow and increases the risk of certain cancers and blood disorders.

"We found out last week that Isaac has cancer in his mouth. TBH, we always knew this day was coming, as it's a near certainty w/ Fanconi anemia," Coleman wrote at the time.

"But it's definitely hitting a little earlier than we hoped and is still just such a shocking thing to hear about your child, even if you've braced for it for years. Been getting lots of scans and we're not sure yet how much it's spread," he continued. "But for now, the plan is to try and remove the cancer surgically asap."

In February, Coleman shared another update, explaining that Isaac’s condition had worsened quickly and doctors classified the cancer as stage 3.

"On the cancer front, we've learned a bit more and it hasn't been good news. He's officially stage 3, although the docs said he's right on the edge of stage 4 because of the speed and aggression of the spread," Coleman wrote.

"So even though the visible cancer has been removed, there's a very high chance that it's still present microscopically & we'll have a tough decision to make soon."

Family canceled 2026 tour plans

Coleman also explained that Fanconi anemia complicated Isaac’s treatment options and limited what doctors could safely do.

"Because of several Fanconi-related complexities, Isaac's treatment options are much more limited than in typical pediatric cancer," he wrote. "Our main options right now are to either start low-dose targeted radiation therapy OR continue to just address the cancer surgically as it shows up."

The entertainer later announced he was canceling Danny Go!’s planned 2026 tour so he could remain home with his family.

"As some of you may know, my oldest son Isaac was diagnosed with stage 3 cancer this past month. As a result, we've made the decision to cancel our tour plans for 2026," the statement read.

"Dancing with so many of you in person over the last 18 months has been a true joy & we hope to get another tour rolling when the time is right."

Isaac’s cancer later spread aggressively

In April, Coleman shared another difficult update, revealing that Isaac’s cancer had continued spreading and that the family had shifted to palliative care focused on comfort.

"Haven't updated on Isaac's cancer in a bit and it's still difficult for me to process and talk about," Coleman wrote. "But the high-level update is that his cancer has continued to spread aggressively and his energy levels have dropped very low."

"He has a hospice team onboard now to help manage the pain & we are just doing our best to make each day as enjoyable and restful as possible for him," he continued. "Mindy and I are heartbroken watching him decline, knowing how frustrating and scary this must be for him. But we're trying to hold it all together & keep soaking up the time we still have with our boy."

Coleman and his wife Mindy are also parents to their younger son Levi, who was born in 2015.
