Berry said he became aware of his latest health issue in November before his latest tour, the magazine reported.
"I had a little catch in my throat, it felt like, it felt exactly like, the skin of a Spanish peanut was stuck in my throat," Berry said in the video.
After examining his tonsils Berry noticed they were swollen. Despite going to a doctor and receiving steroids and antibiotics, the problem persisted, Berry said.
He completed his tour and then saw a doctor Jan. 4, Rolling Stone reported. A CT scan revealed two tumors in his tonsils, so he had surgery to remove them, the magazine reported. After receiving biopsy results, doctors told Berry he had tonsil cancer.
Berry will begin a five-week chemotherapy and radiation treatment plan this week, Rolling Stone reported.
“This particular cancer is one of the most highly treatable, and has an incredible cure rate,” Berry said in his video.
According to his website, Berry had 20 singles on the country charts during the 1990s, six of which were Top 5 songs. He won a Grammy Award in 1996 for his participation in "Amazing Grace: A Country Salute to Gospel, Vol. 1."
