According to the report, she is unsure of her prognosis at this point, but is staying positive that the surgery will be a success. "I will fight every step of the way," she wrote. "My husband and children are counting on me to be there for years to come."

A representative for the family confirmed the news to Hawaii news network KITV. In a statement, the spokesperson said Beth, along with husband Duane "Dog" Chapman, are maintaining a united front during this tough time.

"Beth has been trying hard to remain strong through the worry and fear and anxiety, as she will not know her prognosis until after her surgery. At times, Duane has been inconsolable since hearing the news, but he is determined to remain strong for Beth and their family, 'and pray a lot.' […] Duane shared that people see Beth as a tough lady, but she has a big heart, he told me - and which I know from personal experience."
