Country singer Doug Supernaw has been diagnosed with Stage IV lung and bladder cancer. The '90s country artist is in the hospital and working with doctors to determine a course of treatment, according to a post on his official Facebook page.

According to Facebook, Supernaw was suffering from a cough when he was admitted to a hospital in the Houston, Texas, area and diagnosed with pneumonia. A round of tests found fluid on the artist's heart and lungs, and a "suspicious mass" in his right lung; Supernaw was transferred to another local hospital, where doctors "confirmed several masses in his lungs, lymph nodes, bones and bladder."

"The official diagnoses as of now is advanced, stage four, lung and bladder cancer," the Facebook statement adds. "At this time, Doug remains in the hospital, awaiting more testing, while determining a treatment path."

The post on Supernaw's Facebook page credits his team of doctors "for working so diligently in both the care, and treatment, of our beloved Doug," as well as his family, friends and fans for their prayers and well-wishes. While the statement asks for privacy, it does note that updated will be provided "as necessary."

Supernaw, now 58, is a Texas native who, after spending a few years in Nashville as a songwriter in the late 1980s and early '90s, moved back to the Lone Star State and was signed to BNA Records in 1993. His two albums with the label, 1993's Red and Rio Grande and 1994's Deep Thoughts From a Shallow Mind, produced four Top 30 singles, including the No. 1 "I Don't Call Him Daddy."

Supernaw released two more albums, one in 1996 and one in 1999, with Giant Records and Tack Records, respectively. His most recent release was a greatest hits project, which dropped in the spring of 2017 and included two new songs.
