Mark Kendall, guitarist for Great White, announced on social media that he has been diagnosed with stage four kidney cancer. In a Facebook post, Kendall revealed he received the diagnosis a few months ago but chose to wait before sharing the news publicly until he had more information about his condition.
“Just to give you an update, the tumor has shrunk from 13 centimeters to eight, so I’m going in the right direction with my first scan,” he wrote on Saturday. “There isn’t a cure for cancer, but what I have is manageable. I have the best doctors in the world, and one of them invented immunotherapy, which is the treatment I’m on. I only had to do three radiation treatments, which is a good thing!

Kendall, 68, shared a photo of himself with several members of his medical team alongside the update.
“To be clear, I don’t need any financial help,” the rockstar added, “but I’ll take prayers and encouragement! I’m gonna fight this thing and be okay. People in my support group were diagnosed with my exact issue up to 20 years ago, so that is encouraging! Blessings All!”
