Mark Kendall, the founding guitarist of hard rock band Great White, says his cancer treatment is showing encouraging progress, offering fans a hopeful update after revealing his stage four kidney cancer diagnosis late last year.
Kendall, 68, shared the news in a recent social media post, writing that scans show his tumor has steadily decreased in size since he began treatment. The update marks a positive moment in a battle he first made public in November 2025, after months of privately undergoing medical care.
A Measured Response to a Serious Diagnosis
Kendall said doctors initially found a 13-centimeter tumor, prompting an aggressive treatment plan that includes immunotherapy and limited radiation. According to Kendall, subsequent scans showed the tumor shrinking to 11 centimeters, then 8 centimeters, and most recently to about 5 centimeters, with no evidence that the cancer has spread elsewhere in his body.
“I’m not out of the woods,” Kendall wrote, noting that while cancer does not come with guarantees, his doctors believe the disease is manageable at this stage. He credited his medical team for their expertise and pointed out that one of his doctors helped develop the immunotherapy treatment he is receiving.
Immunotherapy has become a common option for advanced cancers, using the immune system to target cancer cells rather than relying solely on chemotherapy. Kendall said he only required three radiation sessions, a detail he described as encouraging.
Kendall also made it clear that he is not seeking financial assistance. Instead, he asked fans for prayers, positive thoughts, and continued support as he moves forward with treatment.
Fans Rally Behind the Rock Veteran
The update drew an immediate response from fans and fellow musicians, many of whom flooded the comments with messages of relief and encouragement. Supporters praised Kendall for his transparency and resilience, with several noting how meaningful the news felt after a difficult year for Great White fans.
The band has endured a recent loss with the death of former lead singer Jack Russell in 2024. Russell had stepped away from touring after health issues of his own, making Kendall’s health update resonate even more deeply within the rock community.
Great White formed in Los Angeles in 1977 and rose to prominence in the 1980s with hits such as “Once Bitten, Twice Shy,” “Rock Me,” and “Save Your Love.” Kendall’s blues-driven guitar work has long been central to the band’s sound and success.
While Kendall has not announced any immediate plans to return to touring or recording, his latest update signals cautious optimism. For fans who grew up with Great White’s music, the shrinking tumor measurements feel like more than medical data. They represent the possibility that one of rock’s enduring figures still has more chapters left to write, both on and off the stage.
