Bruce Arians had a rough year health-wise in 2016. There was a scare in San Diego in the preseason (Arians had diverticulitis), and then another hospital check after "discomfort" in late November. Now, in his new book released today called "The Quarterback Whisperer," Arians acknowledges there was third health concern that had to be taken care of after the season.

Arians writes that he was out to dinner with his wife, Chris, in December when he got a call from his doctor. Arians had just been to the doctor to get a hernia checked, and his ultrasound revealed a small spot on his kidney -- renal cell carcinoma. Amazingly, Arians coached the remainder of the season before having surgery to remove a "small portion" of the kidney in February.

"Now I feel great," Arians writes. "My energy has returned. I'm told I'm cancer-free again. I'm ready for at least one more season of NFL football–maybe more." Arians had to deal with a lot of heartbreak around that time. Both his brother-in-law and his longtime agent passed away from cancer. Arians also has a history with the disease. He battled prostate cancer in 2007, and had to have some cancerous cells scraped off his nose during his first summer work with the Cardinals in 2013. "I now realize more than ever nothing is guaranteed in life," Arians writes. "Every day needs to 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."
