YouTuber Colby Brock of internet-famous duo Sam & Colby revealed that he is officially cancer-free after two challenging years of treatment.
Sam & Colby are a popular pair of YouTubers best known for exploring abandoned locales and ghost hunting in ‘haunted’ houses.
Colby was diagnosed with testicular cancer in early 2023 after noticing a “bruise-like pain” in his groin in November 2022.
In February 2023, surgeons removed the affected testicle, but admitted that there was still a 35% chance the cancer could return.
Colby Brock first opened up about his cancer treatment in spring 2023.

On May 27, 2025, Colby shared the good news — after two years of chemotherapy, he is officially cancer-free, with only a 2 – 3% chance of the cancer returning.
“The doctors told me back in May 2023 after I finished chemotherapy that if my cancer would return, it would most likely happen within a couple of years,” he explained in a post on X. “Now that I’m at the two year mark since treatment, my chances of getting the same cancer again are now only 2-3% or less.”
He went on to thank his best pal Sam Golbach for learning to cold cap his head in order to save his hair through chemo and driving through Las Vegas to find dry ice. “You were an open ear to me whenever I needed and stuck by my side through it all. Love you man,” Colby wrote.
In the end, the YouTuber urged viewers to pay attention to their bodies and take care of their physical health, saying “the biggest thing I’ve learned throughout the whole process is that health is everything. I never thought I’d get cancer at 25 years old, but it happened and was a huge wake up call that I’m not invincible.”
This latest news comes nearly two years after Colby completed his initial treatment in 2023, undergoing two rounds of chemotherapy that lasted about 21 days each in what he called the “craziest mental challenge of my life.”
Since then, Colby has been able to join Sam on their adventures across the globe in spooky places, most recently getting lost in the 300 kilometers of mass graves in the catacombs buried beneath Paris, France.
