Cardinals coach Bruce Arians stayed on the team's sideline for the final month of the 2016 season despite being diagnosed with cancer, according to his new book, "The Quarterback Whisperer."
In the book, which was released Tuesday, Arians reveals that his doctor called him in December to let him know that a small spot had been found on his kidney. The spot was a form of cancer known as renal cell carcinoma.
Instead of taking the final month off, Arians finished the season and underwent surgery in February. During the successful operation, doctors removed a small portion of Arians' kidney.
"Now I feel great," Arians wrote in the book, via the Cardinals' official website. "My energy has returned. I'm told I'm cancer-free again."
The cancer diagnosis was Arians' third health scare of the 2016 season. The Cardinals coach was, and then again in November . In both instances, Arians was released from the hospital within days.
Arians wrote in his book that he might only coach for one more year because of his health issues.
"I'm ready for at least one more season of NFL football -- maybe more," Arians wrote.
The cancer diagnosis in December was the third one of Arians' lifetime. The Cards' coach was also diagnosed with prostate cancer in 2007 and he had several cancerous cells scraped off his nose in 2013.
After all the health scares, Arians is definitely more appreciative of everything he's been given in life.
"I now realize more than ever nothing is guaranteed in life," Arians writes. "Every day needs to be enjoyed and celebrated to the fullest. Roses need to be smelled, sunsets savored, time with family cherished. Moving forward, I want to be a beacon of hope for others struggling with cancer. My fight is their fight. I'm not coaching for myself in 2017. I'm coaching for everyone who's dealing with cancer. This is my charge."
