In May 2022, Bob was diagnosed with advanced liver cancer when MRI scans revealed a large tumor in the left lobe and multiple smaller ones in the right lobe. He contracted Hepatitis C at age 23 from a blood transfusion during surgery after a cycling accident, and was born with Hemochromatosis, a genetic disorder that can cause severe liver disease. Bob was successfully treated for hepatitis C in 2015, but a lifetime of chronic liver disease led to his cancer.
